Multiphase Equilibria Modeling with GCA-EoS. Part II: Carbon Dioxide with the Homologous Series of Alcohols was written by Gonzalez Prieto, Mariana;Sanchez, Francisco Adrian;Pereda, Selva. And the article was included in Journal of Chemical & Engineering Data in 2018.Formula: C10H22O The following contents are mentioned in the article:

Modeling multiphase equilibrium of mixtures comprising carbon dioxide (CO₂) and organic compounds is a challenge for any equation of state. CO₂ shows a highly nonideal phase behavior with most organic compounds, which is even more pronounced with hydrogen-bonding compounds In this work, we have extended the Group-Contribution with Association equation of state (GCA-EOS) to represent vapor-liquid, liquid-liquid, and vapor-liquid-liquid equilibrium of CO₂ mixtures with primary alcs. The final set of parameters has been challenged against an exptl. database covering C₁-C₁₆ primary alcs., temperatures from 230 to 573 K, and pressures up to 400 bar. Particular attention has been given to describe the critical curves for each binary system correctly, which means attaining the phase equilibrium transformation of the CO₂ + 1-alc. homologous series as the alc. alkyl chain length increases. This parametrization strategy allows reducing the risk of incorrect liquid-liquid split predictions. In addition, using a single set of parameters, fitted to binary data of CO₂ with normal alcs., the model is able to predict the phase behavior of binary mixtures not included in the parametrization procedure, comprising normal and branched alcs. The GCA-EOS predicts properly the overall phase behavior, i.e., the binary critical curves, without losing accuracy in the prediction of saturation points. This study involved multiple reactions and reactants, such as 3,7-Dimethyloctan-1-ol (cas: 106-21-8Formula: C10H22O).

3,7-Dimethyloctan-1-ol (cas: 106-21-8) belongs to alcohols. Under appropriate conditions, inorganic acids also react with alcohols to form esters. To form these esters, a wide variety of specialized reagents and conditions can be used. Grignard and organolithium reagents are powerful tools for organic synthesis, and the most common products of their reactions are alcohols.Formula: C10H22O

Characterisation of taste-active compositions, umami attributes and aroma compounds in Chinese shrimp was written by Chen, Lihua;Zeng, Wenhua;Rong, Yuzhi;Lou, Bao. And the article was included in International Journal of Food Science and Technology in 2021.Category: alcohols-buliding-blocks The following contents are mentioned in the article:

Chinese shrimp is one of the most important aquatic resource in China due to its unique flavor and high nutritional value. In this study, the taste-active components including free amino acids (FAAs), 5′-nucleotides, organic acids, inorganic ions, trimethylamine oxide (TMAO) and betaine were analyzed. The synergistic effect between amino acids and 5′-nucleotides was determined by partial least squares (PLS) anal. The taste activity value (TAV) and equivalent umami concentration (EUC) were calculated to analyze the major taste-active components and umami attributes. Then, the aroma compounds were extracted by simultaneous distillation extraction (SDE), head-space solid-phase microextraction (HS-SPME) and supercritical fluid extraction (SFE) methods, resp., and identified by gas chromatog.-mass spectrometry (GC-MS). Arginine (Arg), glycine (Gly), GMP (5′-GMP), inosine-5′-monophosphate (5′-IMP), de-nosine-5′-monophosphate (5′;-AMP), succinic acid, lactic acid and inorganic ions with TAV higher than 1 contributed greatly to the taste. The umami intensity for 100 g of Chinese shrimp was equivalent to 4.58 g monosodium glutamate (MSG), indicating that Chinese shrimp had relatively high umami taste value. Ninety-seven volatile compounds including esters, alcs., acids, aldehydes, ketones, heterocycles, aromatics and alkanes were identified. This research might help consumers to understand the flavor compositions and promote the development of flavor products of Chinese shrimp. This study involved multiple reactions and reactants, such as 3,7-Dimethyloctan-1-ol (cas: 106-21-8Category: alcohols-buliding-blocks).

3,7-Dimethyloctan-1-ol (cas: 106-21-8) belongs to alcohols. Alcohols are weak acids. The most acidic simple alcohols (methanol and ethanol) are about as acidic as water, and most other alcohols are somewhat less acidic. Converting an alcohol to an alkene requires removal of the hydroxyl group and a hydrogen atom on the neighbouring carbon atom. Dehydrations are most commonly carried out by warming the alcohol in the presence of a strong dehydrating acid, such as concentrated sulfuric acid.Category: alcohols-buliding-blocks

Two novel low band gap donor-acceptor (D-A) copolymers, poly[9,10-bis(4-(dodecyloxy)phenyl)-2,6-anthracene-alt-5,5-(4′,7′-bis(2-thienyl)-2′,1′,3′-benzothiadiazole-N-5,6-(3,7-dimethyloctyl)dicarboxylic imide)] (PPADTBTDI-DMO) and poly[9,10-bis(4-(dodecyloxy)phenyl)-2,6-anthracene-alt-5,5-(4′,7′-bis(2-thienyl)-2′,1′,3′-benzothiadiazole-5,6-N-octyl-dicarboxylic imide)] (PPADTBTDI-8) were synthesized in the present work by copolymerising the bis-boronate ester of 9,10-phenylsubstituted anthracene flanked by thienyl groups as electron-donor units with benzothiadiazole dicarboxylic imide (BTDI) as electron-acceptor units. Both polymers were synthesized in good yields via Suzuki polymerization Two different solubilizing alkyl chains were anchored to the BTDI units in order to investigate the impact upon their solubilities, mol. weights, optical and electrochem. properties, structural properties and thermal stability of the resulting polymers. Both polymers have comparable mol. weights and have a low optical band gap (Eg) of 1.66 eV. The polymers have low-lying HOMO (HOMO) levels of about -5.5 eV as well as the similar LUMO (LUMO) energy levels of -3.56 eV. Thermogravimetric analyses (TGA) of PPADTBTDI-DMO and PPADTBTDI-8 did not prove instability with decomposition temperatures at 354 and 313°C, resp. Powder X-ray diffraction (XRD) studies have shown that both polymers have an amorphous nature in the solid state, which could be used as electrolytes in optoelectronic devices.

3,7-Dimethyloctan-1-ol (cas: 106-21-8) belongs to alcohols. The oxygen atom of the strongly polarized O―H bond of an alcohol pulls electron density away from the hydrogen atom. This polarized hydrogen, which bears a partial positive charge, can form a hydrogen bond with a pair of nonbonding electrons on another oxygen atom. Secondary alcohols are easily oxidized without breaking carbon-carbon bonds only as far as the ketone stage. No further oxidation is seen except under very stringent conditions.Reference of 106-21-8

And the article was included in Food Control in 2018.Recommanded Product: 106-21-8 The following contents are mentioned in the article:

The effect of six salts of different geog. areas on the quality of salted anchovies was evaluated. The crude salts were chem. characterized by determination of inorganic and volatile organic compounds (VOCs). Salted anchovies, corresponding to six exptl. trials, were subjected to microbiol., chem. (including histamine content) and sensory anal. during the entire period of ripening (150 days). The salts were characterized by marked differences in terms of major cations and trace element amounts Among the 27 VOCs detected, octadecane was the most abundant compound and the main differences of the salts were registered for alkanes and alcs. During maturation, significant microbiol. differences between the salts were found for the levels of total aerobic mesophilic microorganisms, lactic acid bacteria, Staphylococcaceae and Enterobacteriaceae counts. All salted anchovies contained histamine below the thresholds allowed by current regulations, but statistical differences were registered for the concentrations of the different trials. Consistent differences were also revealed for their sensory profiles, in particular concerning odor and taste and overall acceptability. Several differences were also detected for dryness, brown color, putrid odor, rancid and raw blood taste sensory attributes. Especially the differences in the composition (chem. and VOC’s) of the raw salts used for the production of salted anchovies has a significant effect on the sensory characteristics of the final product.

The role of halogens in the catalyst transfer polycondensation for π-conjugated polymers was written by Ye, Shuyang;Foster, Scott M.;Pollit, Adam A.;Cheng, Susan;Seferos, Dwight S.. And the article was included in Chemical Science in 2019.Category: alcohols-buliding-blocks The following contents are mentioned in the article:

Catalyst transfer polycondensation is the only method to prepare π-conjugated polymers in a chain-growth manner, yet several aspects that underlie this polymerization are not fully understood. Here, we investigate the nickel-catalyzed polymerization mechanisms of a series of thiophene monomers bearing different halogen functionalities (Cl, Br, I). We have discovered the significant role that halogens and magnesium salts play in this polymerization More specifically, the catalyst resting state changes depending on the type of halogenated monomer. For chlorinated monomers a mixture of Ni(II)-dithienyl and dissociated Ni(phosphine) complexes are the resting states, which results in uncontrolled polymerization For brominated monomers, a Ni(II)-dithienyl complex is the resting state, which leads to controlled polymerization For iodinated monomers, a Ni(II)-thienyl iodide complex is the resting state, and notable inhibition by magnesium salt byproducts is observed The catalyst resting state changes to a Ni(II)-dithienyl complex when a turbo Grignard reagent (i-PrMgCl.LiCl) is used. These findings are used to guide the design of a new monomer, 2-bromo-3-(2-ethylhexyl)-5-iodotellurophene, which enables the first controlled polymerization of a tellurophene monomer containing a sterically encumbered 2-ethylhexyl side chain. These insights are crucial for deepening the mechanistic understanding of Kumada cross coupling reactions and the controlled synthesis of π-conjugated polymers.

New dendrimers containing ruthenium nanoparticles as catalysts for hydrogenation of citral to 3,7-dimethyloctanol was written by Keshtiara, Parastoo;Hadadzadeh, Hassan;Daryanavard, Marzieh;Mousavi, Negin;Dinari, Mohammad. And the article was included in Materials Chemistry and Physics in 2020.HPLC of Formula: 106-21-8 The following contents are mentioned in the article:

Two silica-supported dendrimers containing ruthenium nanoparticles (S-D/RuNPs) have been synthesized through the divergent method and characterized by the attenuated total reflectance-IR (ATR-IR), field-emission SEM (FE-SEM), transmission electron microscopy (TEM), Brunauer-Emmett-Teller (BET), X-ray diffraction (XRD), and inductively coupled plasma (ICP) techniques. To prepare S-D/RuNPs, a first-generation dendrimer was synthesized from hexakis(bromomethyl)benzene (hex) core and vanillin branches. In the next step, second-generation dendrimers, hexpyD and hexbzaD, were synthesized by the reaction of the first-generation dendrimer with ortho-aminopyridine (py) and para-aminobenzoic acid (bza), resp. The second-generation dendrimers, hexpyD and hexbzaD, were then reacted with ruthenium(III) chloride to form the hexanuclear Ru(III) complexes which were immobilized on a silica support and reduced by NaBH₄ in 2-methoxyethanol as the solvent. The mean size of the ruthenium nanoparticles encapsulated within the dendrimers was found to be 2 and 6 nm in hexpyD and hexbzaD, resp. In addition, the catalytic activity of the synthesized nanoparticles were investigated on the hydrogenation of citral (3,7-dimethyl-2,6-octadienal) to 3,7-dimethyloctanol. The effect of S-D/RuNPs catalysts on the hydrogenation reaction was monitored by gas chromatog.-mass spectrometry (GC/MS). The results revealed that the increase of the reaction temperature and reaction time leads to a higher reaction yield at a constant pressure.

Effect of Biocompatible Esters and Alcohols as Cosurfactants on Structure and Solubilization Behavior of the Zwitterionic Surfactant Tetradecyldimethylamine Oxide was written by Gradzielski, Michael;Horbaschek, Klaus;Deme, Bruno. And the article was included in Industrial & Engineering Chemistry Research in 2019.Computed Properties of C10H22O The following contents are mentioned in the article:

In this work, we compare the effect of different monoterpenoid alcs. that differ with respect to their number of double bonds and simple aromatic esters of variable mol. architecture as cosurfactants on the phase behavior of the zwitterionic surfactant tetradecyldimethylamine oxide (TDMAO) and its solubilization behavior, with respect to decane as a model paraffin oil. The esters are shown to be potent cosurfactants but require higher concentrations to achieve similar effects, with respect to structural changes and solubilization enhancement. Compared to the alcs., they solubilize somewhat smaller amounts of decane, do reduce the interfacial tension substantially less, and also do not form an isotropic phase of unilamellar vesicles (L₄) but directly multilamellar vesicles (L_αl). A very interesting effect is the significance of the detailed mol. architecture of the esters, as Et benzoate and benzyl acetate, both having the same sum formula, differ significantly, with respect to their cosurfactant properties. However, all systems allow one to incorporate relatively large amounts of the oil. For the case of the esters, this always leads to the formation of oil-in-water (O/W) microemulsion droplets while the alcs. can build in relatively large amounts of oil within their vesicular structures. These findings show that these biofriendly cosurfactants allow to formulate structurally rather versatile systems and efficiently enhance oil solubility for the given surfactant system. This study involved multiple reactions and reactants, such as 3,7-Dimethyloctan-1-ol (cas: 106-21-8Computed Properties of C10H22O).

Renewable Terpene Derivative as a Biosourced Elastomeric Building Block in the Design of Functional Acrylic Copolymers was written by Noppalit, Sayrung;Simula, Alexandre;Ballard, Nicholas;Callies, Xavier;Asua, Jose M.;Billon, Laurent. And the article was included in Biomacromolecules in 2019.Related Products of 106-21-8 The following contents are mentioned in the article:

In order to move away from traditional petrochem.-based polymer materials, it is imperative that new monomer systems be sought out based on renewable resources. In this work, the synthesis of a functional terpene-containing acrylate monomer (tetrahydrogeraniol acrylate, THGA) is reported. This monomer was polymerized in toluene and bulk via free-radical polymerizations, achieving high conversion and mol. weights up to 278 kg·mol^-1. The synthesized poly(THGA) shows a relatively low T_g (-46 °C), making it useful as a replacement for low T_g acrylic monomers, such as the widely used Bu acrylate. RAFT polymerization in toluene ([M]₀ = 3.6 mol·L^-1) allowed for the well-controlled polymerization of THGA with ds.p. (DP_n) from 25 to 500, achieving narrow mol. weight distributions (D ≈ 1.2) even up to high conversions. At lower monomer concentrations ([M]₀ = 1.8 mol·L^-1), some evidence of intramol. chain transfer to polymer was seen by the detection of branching (arising from propagation of midchain radicals) and terminal double bonds (arising from β-scission of midchain radicals). Poly(THGA) was subsequently utilized for the synthesis of poly(THGA)-b-poly(styrene)-b-poly(THGA) and poly(styrene)-b-poly(THGA)-b-poly(styrene) triblock copolymers, demonstrating its potential as a component of thermoplastic elastomers. The phase separation and mech. properties of the resulting triblock copolymer were studied by at. force microscopy and rheol.

Synthesis and Characterization of Partially and Fully Saturated Menaquinone Derivatives was written by Koehn, Jordan T.;Crick, Dean C.;Crans, Debbie C.. And the article was included in ACS Omega in 2018.COA of Formula: C10H22O The following contents are mentioned in the article:

Menaquinones (MK) contain both a redox active quinone moiety and a hydrophobic repeating isoprenyl side-chain of varying length and degrees of saturation This characteristic structure allows MKs to play a key role in the respiratory electron transport system of some prokaryotes by shuttling electrons and protons between membrane-bound protein complexes, which act as electron acceptors and donors. Hydrophobic MK mols. with partially and fully saturated isoprenyl side-chains are found in a wide range of eubacteria and Archaea and the structural variations of the MK analogs are evolutionarily conserved but poorly understood. For example, Mycobacterium tuberculosis, the causative agent of tuberculosis, uses predominantly MK-9(II-H₂) (saturated at the second isoprene unit) as its electron carrier and depends on the synthesis of MK-9(II-H₂) for survival in host macrophages. Thus, MKs with partially saturated isoprenyl side-chains may represent a novel virulence factor. Naturally occurring longer MKs are very hydrophobic, while MK analogs that have a truncated (i.e., 1-3 isoprenes) isoprenyl side-chain are less hydrophobic. This improves their solubility in aqueous solutions allowing rigorous study of their structure and biol. activity. We present the synthesis and characterization of two partially saturated MK analogs, MK-2(II-H₂) I and MK-3(II-H₂) II, and two novel fully saturated MK derivatives, MK-2(I,II-H₄) III and MK-3(I,II,III-H₆) IV.
