Characterization of Esters of fatty Acids and Dicarboxylic Acids with Guerbet Alcohols
نویسنده
چکیده
Esters oi some common iatty acids and diacids with Guerbet alcohols were prepared by p-toluenesulionic acidcat~lyzed esteriiication. Such materials are oi interest in applications such as additives in various industrial products. Gas chromatography-mass spectrometry with chemical ionization using methane as ionization gas is an efficient characterization method ior these Guerbet esters and diesters. Under these conditions, structural ieatures such as molecular weight and site oi branching are easily determined. The spectra oi the present compounds were compared to those oi di-Guerbet esters reported earlier and differences noted. The compounds were also characterized by l3e nuclear magnetic resonance spectroscopy. Paper no. )9769 in JADeS 78,537-540 (May 2001).

Synthesis of neopentyl glycol and ethylene glycol esters by fatty acids in the presence of acidic ion exchange resin catalyst
A most effective and less energy demanding method of producing fatty esters, diol esters, by esterifying fatty acids, with neopentyl and ethylenglycol alcohols in the presence of an acidic ion exchange resin catalyst(polyestyrendivinylbenzensulfated) was investigated at elevated temperature. In this process an azeotroping agent, toluene, was used to facilitate continuous removal of water by dis...
متن کاملDesign and synthesis of new esters of terpenoid alcohols as 15-lipoxygenase inhibitors
Objective(s): 15-Lipoxygenases are one of the iron-containing proteins capable of performing peroxidation of unsaturated fatty acids in animals and plants. The critical role of enzymes in the formation of inflammations, sensitivities, and some cancers has been demonstrated in mammals. The importance of enzymes has led to the development of mechanistic studies, product analysis, and synthesis of ...
متن کاملRegioselective oxygenation of fatty acids, fatty alcohols and other aliphatic compounds by a basidiomycete heme-thiolate peroxidase.
Reaction of fatty acids, fatty alcohols, alkanes, sterols, sterol esters and triglycerides with the so-called aromatic peroxygenase from Agrocybe aegerita was investigated using GC-MS. Regioselective hydroxylation of C(12)-C(20) saturated/unsaturated fatty acids was observed at the ω-1 and ω-2 positions (except myristoleic acid only forming the ω-2 derivative). Minor hydroxylation at ω and ω-3 ...
متن کاملExpansion of the ω‐oxidation system AlkBGTL of Pseudomonas putida GPo1 with AlkJ and AlkH results in exclusive mono‐esterified dicarboxylic acid production in E. coli
The AlkBGTL proteins coded on the alk operon from Pseudomonas putida GPo1 can selectively ω-oxidize ethyl esters of C6 to C10 fatty acids in whole-cell conversions with Escherichia coli. The major product in these conversions is the ω-alcohol. However, AlkB also has the capacity to overoxidize the substrate to the ω-aldehyde and ω-acid. In this study, we show that alcohol dehydrogenase AlkJ and...
