Carbonnier, Maxime published the artcileAn experimental and modeling study of the oxidation of 3-pentanol at high pressure, Safety of 3-Pentanol, the main research area is pentanol oxidation high pressure.

High pressure oxidation of 3-pentanol is investigated in a jet-stirred reactor and in a shock tube. Experiments in the reactor were carried out at 10 atm, between 730 and 1180 K, for equivalence ratios of 0.35, 0.5, 1, 2, 4 and 1000 ppm fuel, at a constant residence time of 0.7 s. Reactant, product and intermediate species mole fractions were recorded using Fourier transform IR spectroscopy (FTIR) and gas chromatog. (GC). Ignition delay times were measured for 3-pentanol/O2 mixtures in argon in a shock tube at 20 and 40 bar, in a temperature range of 1000-1470 K and for equivalence ratios of 0.5, 1 and 2. The fuel did not show any low-temperature reactivity under these conditions in neither exptl. set-up and produced various aldehydes and ketones as well as the olefin 2-pentene as intermediates. A kinetic sub-mechanism is developed in order to represent the present data and analyze the reaction pathways.

Zhang, Hong published the artcileImproved Process for the Palladium-Catalyzed C-O Cross-Coupling of Secondary Alcohols, Application of 3-Pentanol, the main research area is aromatic ether preparation; aryl halide secondary alc coupling reaction palladium catalyst.

An improved protocol for the Pd-catalyzed I C-O cross-coupling of secondary alcs. ROH (R = butan-2-yl, 2,2,2-trifluoro-1-phenylethyl, cyclopropyl(phenyl)methyl, etc.) is described. The use of biaryl phosphine as the ligand was key to achieving efficient cross-coupling of (hetero)aryl halides ArX (X = Cl, Br; Ar = 4-tert-butylphenyl, naphthalen-1-yl, 4-methylpyridin-2-yl, etc.) with only a 20% molar excess of the alc. Addnl., an unusual reactivity difference between an electron-rich aryl bromide and the analogus aryl chloride, and deuterium-labeling suggested that currently unidentified pathways for reduction play an important role in explaining this disparity were observed

Ramos-Escudero, Fernando published the artcileAssessment of phenolic and volatile compounds of commercial Sacha inchi oils and sensory evaluation, Recommanded Product: 3-Pentanol, the main research area is sacha inchi oil phenolic volatile compound sensory property; Authentication; Oil; Phenolic profile; Plukenetia volubilis seed; Sensory properties; Volatile profiles.

Sacha inchi is a super seed primarily grown in the Amazon rainforest of Peru. One of the main products obtained from seeds is oil. This product is rich in polyunsaturated fatty acids, tocopherols, and sterols. The objective of this work was to authenticity evaluate of the Sacha inchi oil by means of characterization of phenols, volatile compounds, and sensory profile. The phenolic and volatile compounds were analyzed using liquid chromatog.-electrospray ionization-time of flight/mass spectrometry (HPLC-ESI-TOF/MS) and headspace solid phase microextraction combined with gas chromatog. and mass spectrometry (HS-SPME/GC-MS), resp. A total of 16 phenolic compounds were detected in com. Sacha inchi oils, while 54 compounds have been found in the volatile fraction. These compounds mainly correspond to notes generated by alcs., aldehydes, acids, ketones, and terpenoids. Principal component anal. (PCA) showed that the first two PCs account for 71.13% of total variance. Statistical anal. was used to observe the relationships between phenolic and volatile compounds; therefore, consequently, it has been found that 16 volatile compounds may have a significant influence upon overall perceived flavor and odor of the com. Sacha inchi oils. According to the odor and flavor, the Sacha inchi oil is characterized by “”green”” odor notes, seed, dried fruit and rough.

Fokin, Igor published the artcileChemoselective Electrochemical Hydrogenation of Ketones and Aldehydes with a Well-Defined Base-Metal Catalyst, COA of Formula: C5H12O, the main research area is alc preparation chemoselective green chem; ketone electrochem hydrogenation manganese complex catalyst; aldehyde electrochem hydrogenation manganese complex catalyst; catalysis; homogeneous catalysis; molecular electrochemistry; reaction mechanisms; spectroelectrochemistry.

An electrochem. method for the hydrogenation of ketones RC(O)R1 [R = Me, Et; R1 = CH3, CH2CH3, (CH2)2CH3, (CH2)2CH=C(CH3)2, (CH2)2CH=CH2] and aldehydes R2CHO [R2 = (CH2)3CH3, (CH2)4CH3, (CH2)2CH=CH2] by in situ formation of a Mn-H species has been described. The protons and elec. current as surrogate for H2 and a base-metal complex to form selectively the alcs. RCH(OH)R1 and R2CH2OH have been described. The method is chemoselective for the hydrogenation of C=O bonds over C=C bonds. Mechanistic studies revealed initial 3 e- reduction of the catalyst forming the steady state species [Mn2(H-1L)(CO)6]-. Subsequently, the protonation, reduction and internal proton shift forming the hydride species has been described. Finally, the transfer of the hydride and a proton to the ketone yields the alc. and the steady state species is regenerated via reduction The interplay of two manganese centers and the internal proton relay represent the key features for ketone and aldehyde reduction as the resp. mononuclear complex and the complex without the proton relay are barely active.

Tian, Huaixiang published the artcileScreening of aroma-producing lactic acid bacteria and their application in improving the aromatic profile of yogurt, Formula: C5H12O, the main research area is aroma lactic acid bacteria yogurt aromatic profile; Lactobacillus plantarum ; adjunct culture; aroma profile; yogurt.

The development of yogurt flavor is a complicated and dynamic biochem. process. In addition to traditional starter cultures, adjunct cultures could also make significant contributions to the flavor profiles of yogurt. In the current study, two Lactobacillus plantarumstrains (1-33 and 1-34) were isolated based on their abilities to produce acetaldehyde and diacetyl. In co-fermentation with traditional starters, these isolated strains were able to maintain viability without affecting the yogurt’s acidification profiles. Furthermore, they pos. influenced the aroma quality of the yogurt samples. They promoted the formation of volatile metabolites, especially acetaldehyde, diacetyl, and acetoin, which are recognized as characteristic compounds The results of this work provide novel knowledge about the contributions of isolated strains on the flavor profiles of yogurt, which will help to improve the organoleptic properties of the final products. Practical applications : Using lactic acid bacteria (LAB) as adjunct cultures co-fermented with traditional yogurt starter cultures can increase the quantities of flavor compounds in yogurt. This study enriches our understanding of the effects of adjunct cultures on yogurt flavor. Researchers and manufacturers that specialize in yogurt making can use the results of this study to improve the aromatic profile and organoleptic quality of yogurt.

Mohanta, Nirmala published the artcileRapid and Multigram Synthesis of Vinylogous Esters under Continuous Flow: An Access to Transetherification and Reverse Reaction of Vinylogous Esters, Safety of 3-Pentanol, the main research area is vinylogous ester multigram preparation transetherification.

An environmentally benign approach for the synthesis of vinylogous esters from 1,3-diketone and its reverse reaction under continuous-flow was developed with alcs. in the presence of inexpensive Amberlyst-15 as a catalyst. This methodol. is highly selective and general for a range of cyclic 1,3-dicarbonyl compounds which gives a library of linear alkylated and arylated vinylogous esters in good to excellent yield under solvent and metal free condition. Furthermore, the long-time experiment in a continuous-flow up to 40 h afforded 8.0 g of the vinylogous ester with turnover number (TON) = 28.6 and turnover frequency (TOF) = 0.715 h-1 using Amberlyst-15 as a catalyst. Furthermore, a continuous-flow sequential transetherification of vinylogous esters with various alcs. was achieved in high yield. Reversibly, this vinylogous ester was deprotected or hydrolyzed into ketone using environmentally benign water as a solvent and Amberlyst-15 as a catalyst under continuous-flow process.
