This study was to evaluate the effects of microwave and conventional processing methods on the aroma profiles of fenugreek seeds and flours. The volatiles of raw, sprouted, boiled, roasted, and micro-waved fenugreek grains were evaluated using headspace-solid phase micro-extraction (HS-SPME) coupled to gas chromatog.-mass spectrometry (GC-MS). 51 and 60 volatiles were detected in the emission bouquets of raw and processed seeds and flours, resp. Volatiles were divided into seven chem. classes, including monoterpenes hydrocarbons, sesquiterpenes hydrocarbons, phenylpropanoids, non-terpenes derivatives, apocarotenes, nitrogen/sulfur derivative and oxygenated monoterpenes. The data showed that volatiles were significantly affected by the type of processing. All treatments increase the amounts of volatiles including aldehydes, alcs., esters, and alkanes except for the microwave heating. Indeed, the dominant volatiles in microwaved fenugreek were pyrazines, with chocolate aroma like flavor. The microwave heating is based on an energy-efficient and water-saving technol.; it is an interesting and more sustainable technique to be employed in the legume processing. The findings of this study demonstrate that microwave technol. has potential for fenugreek processing. This study involved multiple reactions and reactants, such as 3,7-Dimethyloctan-1-ol (cas: 106-21-8Electric Literature of C10H22O).

3,7-Dimethyloctan-1-ol (cas: 106-21-8) belongs to alcohols. A strong base can deprotonate an alcohol to yield an alkoxide ion (R―O−). For example, sodamide (NaNH2), a very strong base, abstracts the hydrogen atom of an alcohol. 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.Electric Literature of C10H22O

Production and Characterization of Odorless Antioxidative Hydrolyzed Collagen from Seabass (Lates calcarifer) Skin Without Descaling was written by Benjakul, Soottawat;Karnjanapratum, Supatra;Visessanguan, Wonnop. And the article was included in Waste and Biomass Valorization in 2018.Recommanded Product: 106-21-8 The following contents are mentioned in the article:

Odorless hydrolyzed collagen (HC) powder from fish skin with antioxidative activity has gained increasing demand. This investigation aimed to compare the impacts of different hydrolysis processes of seabass skin without descaling as well as spray-drying conditions on characteristics and antioxidative activities of resulting HC. For one-step hydrolysis, 3% papain at 40 °C for 3 h (P) or 2% alcalase at 50 °C for 2 h (A) were used. Two-step hydrolysis, conducted as stepwise process using the combination of both processes, included P + A and A + P. P + A process rendered the HC with higher yield, hydroxyproline recovery, α-amino group content and antioxidative activities, compared to one-step process and A + P process (P < 0.05). HC powder obtained from spray-drying with inlet temperature of 200 °C showed the lower abundance of odorous compounds, compared with that using 150 °C. Nevertheless, no differences in antioxidative activity were obtained between both HCs (P > 0.05). The odorless antioxidative HC powder possessed high pH and thermal stability. Therefore, the combination of appropriate processes including hydrolysis and drying could yield the odorless antioxidative HC powder, which could widen the applications in food or pharmaceutical products. This study involved multiple reactions and reactants, such as 3,7-Dimethyloctan-1-ol (cas: 106-21-8Recommanded Product: 106-21-8).

3,7-Dimethyloctan-1-ol (cas: 106-21-8) belongs to alcohols. Because alcohols are easily synthesized and easily transformed into other compounds, they serve as important intermediates in organic synthesis. The most common reactions of alcohols can be classified as oxidation, dehydration, substitution, esterification, and reactions of alkoxides.Recommanded Product: 106-21-8

Synthesis of “Nereid”, new phenol-free detergent to replace triton X-100 in virus inactivation was written by Farcet, Jean-Baptiste;Kindermann, Johanna;Karbiener, Michael;Scheinecker, Richard;Kostner, Otto;Kreil, Thomas R.. And the article was included in Journal of Medical Virology in 2021.SDS of cas: 106-21-8 The following contents are mentioned in the article:

In the 1980s, virus inactivation steps were implemented into the manufacturing of biopharmaceuticals in response to earlier unforeseen virus transmissions. The most effective inactivation process for lipid-enveloped viruses is the treatment by a combination of detergents, often including Triton X-100 (TX-100). Based on recent environmental concerns, the use of TX-100 in Europe will be ultimately banned, which forces the pharmaceutical industry, among others, to switch to an environmentally friendly alternative detergent with fully equivalent virus inactivation performance such as TX-100. In this study, a structure-activity relationship study was conducted that ultimately led to the synthesis of several new detergents. One of them, named “Nereid”, displayed inactivation activity fully equivalent to TX-100. The synthesis of this replacement candidate has been optimized to allow for the production of several kg of detergent at lab scale, to enable the required feasibility and comparison virus inactivation studies needed to support a potential future transition. The 3-step, chromatog.-free synthesis process described herein uses inexpensive starting materials, has a robust and simple work-up, and allows production in a standard organic laboratory to deliver batches of several hundred grams with >99% purity. This study involved multiple reactions and reactants, such as 3,7-Dimethyloctan-1-ol (cas: 106-21-8SDS of cas: 106-21-8).

3,7-Dimethyloctan-1-ol (cas: 106-21-8) belongs to alcohols. A strong base can deprotonate an alcohol to yield an alkoxide ion (R―O−). For example, sodamide (NaNH2), a very strong base, abstracts the hydrogen atom of an alcohol. Alcohols may be oxidized to give ketones, aldehydes, and carboxylic acids. These functional groups are useful for further reactions. Oxidation of organic compounds generally increases the number of bonds from carbon to oxygen (or another electronegative element, such as a halogen), and it may decrease the number of bonds to hydrogen.SDS of cas: 106-21-8

Prediction of the Normal Boiling Points and Enthalpy of Vaporizations of Alcohols and Phenols Using Topological Indices was written by Arjmand, F.;Shafiei, F.. And the article was included in Journal of Structural Chemistry in 2018.Related Products of 106-21-8 The following contents are mentioned in the article:

Establishing quant. correlations between various mol. properties and chem. structures is of great technol. importance for environmental and medical aspects. These approaches are referred to as Quant. Structure-Property Relationships (QSPR), which relate the physico-chem. or thermodn. properties of compounds to their structures. The main goal of QSPR studies is to find a math. relationship between the property of interest and a number of mol. descriptors derived from the structure of the mol. The current study presents the relationship between the Randic’ (¹χ), Balaban (J),Wiener polarity (W_p), Hyper Wiener (WW), Szeged (Sz), Harary (H) and Wiener (W) indexes to the normal b.ps. (T_bp, K) and the standard enthalpies of vaporization (ΔH⁰_vap, kJ/mol^-1) of 227 alcs. and phenols. The multiple linear regression (MLR) and backward methods were employed to give the QSPR models. After MLR anal., we studied the validation of linearity between the mol. descriptors in the best models for used properties. The results have shown that three descriptors (W, ¹χ, J) could be efficiently used for estimating the normal b.ps., and two descriptors (¹χ, J) could be used for modeling and predicting the standard enthalpies of vaporization of considered compounds This study involved multiple reactions and reactants, such as 3,7-Dimethyloctan-1-ol (cas: 106-21-8Related Products of 106-21-8).

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.Related Products of 106-21-8

Paving the Way to Sustainable Waterborne Pressure-Sensitive Adhesives Using Terpene-Based Triblock Copolymers was written by Noppalit, Sayrung;Simula, Alexandre;Billon, Laurent;Asua, Jose M.. And the article was included in ACS Sustainable Chemistry & Engineering in 2019.Safety of 3,7-Dimethyloctan-1-ol The following contents are mentioned in the article:

Emerging pressure-sensitive adhesives (PSAs) formulations based on triblock copolymers typically rely on solvent-borne or bulk processes and are mostly composed of petroleum-derived monomers. Herein, we aim to go beyond the status quo and synthesize hard-soft-hard and soft-hard-soft triblock copolymers using tetrahydrogeraniol acrylate (THGA) and cyclademol acrylate (CDMA) as biosourced monomers. Great care is taken on the synthesis of the monomers and polymers thereof to minimize the environmental impact of the entire process. Hence, the copolymers are obtained by reversible addition-fragmentation chain transfer (RAFT) miniemulsion polymerization as a waterborne process. The process is readily scalable, as no intermediate purification of the first block is required. Good control is achieved for the triblock copolymers with high mol. weight, with M_n ≈ 105 500 g·mol^-1 and D ≈ 1.6 for the PTHGA-b-PCDMA-b-PTHGA. The nanophase segregation of the copolymers is later evidenced by at. force microscopy (AFM) and rheol. measurements. Finally, the formulations show good adhesive performance, in comparison to triblock copolymers partially based on styrene. Readily scalable triblock copolymer features based on terpene derivatives are paving the way to sustainable waterborne pressure-sensitive adhesives.

Cascade transformations of (±)-citronellal to menthol over extruded Ru-MCM-41 catalysts in a continuous reactor was written by Vajglova, Zuzana;Kumar, Narendra;Peurla, Markus;Eranen, Kari;Maki-Arvela, Paivi;Murzin, Dmitry Yu. And the article was included in Catalysis Science & Technology in 2020.Name: 3,7-Dimethyloctan-1-ol The following contents are mentioned in the article:

Cascade transformations of (±)-citronellal in a continuous mode were investigated over a bifunctional shaped ruthenium catalyst bearing metal clusters of the size 7-13 nm. Four types of Ru/H-MCM-41 extrudates (1.5 x 10 mm) containing 30% of Bindzil-50/80 colloidal silica binder were prepared varying in metal location and metal-to-acid ratio, while the concentration of Bronsted and Lewis acid sites and textural properties of the final extrudates were comparable. Catalytic tests were performed in the trickle-bed reactor under 70°C, 10 bar of H₂, and the initial reactant concentration in cyclohexane 0.086 mol L^-1 for the liquid residence time of 12.5 min. As a reactant, isopulegol, citronellol or (±)-citronellal was used. Metal location in extrudates has a significant effect on the catalytic activity and selectivity especially in terms of isopulegol isomers which content correlated with the metal-to-acid site ratio. Stereoselectivity to the desired (±)-menthol was 68-70%. The highest amount of the desired menthol, 32% yield, was obtained over extrudates where Ru was deposited on the catalytic support, i.e. with the shortest distance between the acid and metal sites, the lowest Bronsted acidity, the lowest Bronsted-Lewis acid sites ratio, the highest sp. surface area and the narrowest range of the Ru particle size distribution.

Menthol synthesis is possible through citral and citronellal hydrogenations via following multistage chem. reactions such as hydrogenation and cyclization. This research mainly focuses on a design of selective, active and cost-effective metal-acid (bifunctional) catalysts for menthol production via citral and citronellal hydrogenations. More specifically, Pd and Ni metals were impregnated over acidic support (e.g., hetero-poly acid supported montmorillonite, HPA_MM). The prepared catalysts were characterized by BET, pyridine adsorption and amine titration methods. Some of the most important parameters such as metal type and loading; applied pressure and reaction time have been investigated throughout this work. The obtained results reveals that the 8 wt% Ni-HPA-MM catalyst (Cat-5) has produced 63% menthols (initial reaction rate 0.126 mmol/min) from citral hydrogenation (80°C, 1.0 MPa) within 24 h. Similarly, during lower applied pressure (0.5 MPa), the production of menthol was significantly improved (approx. 98% of menthol, initial reaction rate ~0.138 mmol/min) with the application of 8 wt% Ni-HPA-MM catalyst (Cat-5) in citronellal hydrogenation. Higher menthol selectivity was achieved from both reactions (citral and citronellal hydrogenation) which might be due to the presence of strong Lewis and medium Bronsted acid sites.
