Epoxidation of bio-derived plant oils is a sustainable route to manufacturing plasticizers, additives in lubricants, and other chemicals. The traditional synthetic approaches suffer from the employment corrosive mineral acid or expensive peroxides (e.g., H2O2). In this work, we report epoxidation using O2 as terminal oxidant catalyzed by Co-N-C/SiO2 single-atom catalyst. dispersion cobalt confi...

The 1,2-(CH2 P(1-adamantyl)2 )2 C6 H4 (dadpx) coordinated palladium complex [(dadpx)Pd(OTf)2 ] (1) is a catalyst precursor for the isomerizing methoxycarbonylation of the internal double bond of methyl oleate, with an unprecedented selectivity (96 %) for the linear diester 1,19-dimethyl nonadecanedioate. Rapid formation of the catalytically active solvent-coordinated hydride species [(dadpx)PdH...

Reactions of ozone with oleic acid or methyl oleate were carried out in presence of hexane, carbon tetrachloride, ethanol or water. All the reaction mixtures were studied by H Nuclear Magnetic Resonance Spectroscopy (H-NMR). Differences in the composition of the reaction mixture of the samples by 1H-NMR analysis were found. During the ozonation of oleic acid, the acyl-oxy-alquil-hydroperoxides ...

The induction of fatty acid synthetase activity in rat liver is markedly reduced by feeding a diet containing a source of linoleate. Within 48 h after changing from a fat-free, high carbohydrate diet to one containing 15% by weight of safflower oil, the specific activity of rat liver fatty acid synthetase is approximately 2-fold lower than that from rats fed a fat-free diet througout. In contra...

The synthesis of sugar fatty acid esters (SFAEs) from lignocellulosic biomass and oleic (C18:1) was catalyzed by immobilized-stabilized derivatives Candida antarctica lipase B in a methyl ethyl ketone medium. After steam-explosion pretreatment mixed hardwoods enzymatic hydrolysis at 15%wt solids, xylose glucose were purified/concentrated to mass ratio ~3 1. These sugars superior commercial as t...

The temnporal changes in oleate oxidation, lipogenesis, malonyl-CoA concentration and sensitivity of carnitine palmitoyjtransferase I (CPT 1) to malonyl-CoA inhibition were studied in isolated rabbit hepatocytes and mitochondria as a function of time after birth of the animal or time in culture after exposure to glucagon, cyclic AMP or insulin. (1) Oleate oxidation was very low during the first...
