Catalytic epoxidation of a technical mixture of methyl oleate and methyl linoleate in ionic liquids using MoO(O2)2.2QOH (QOH = 8-quinilinol) as catalyst and NaHCO3 as co-catalyst.

Shuang-Fei Cai et al.

Molecules (Basel, Switzerland), 14(8), 2935-2946 (2009-08-25)

The oxo-diperoxo molybdenum(VI) complex MoO(O(2))(2).2QOH (QOH = 8-quinilinol) was prepared and characterized by elemental analysis, IR and UV-Vis spectra. The ionic liquids (ILs) [bmim][BF(4)], [hydemim][BF(4)], and [bmim][PF(6)] were characterized by (1)H-NMR and UV-Vis spectra. The epoxidation of a technical mixture

We describe a new class of biomaterials with potential for a variety of applications in tissue engineering, wound healing, and transdermal drug delivery. These materials are based on oleic methyl ester (OME), which is derived from various plant oils including

Solvent-modulated nucleation and crystallization kinetics of 12-hydroxystearic acid: a nonisothermal approach.

Michael A Rogers et al.

Langmuir : the ACS journal of surfaces and colloids, 25(15), 8556-8566 (2009-03-31)

The solvent type strongly affects the nucleation behavior of 12HSA and therefore strongly influences the peak nucleation rate, fiber length, spatial distribution of mass, and degree of branching. Using nonisothermal kinetic models, a correlation was established among the activation energy

Quantitative analysis of pheromone-binding protein specificity.

S Katti et al.

Insect molecular biology, 22(1), 31-40 (2012-11-06)

Many pheromones have very low water solubility, posing experimental difficulties for quantitative binding measurements. A new method is presented for determining thermodynamically valid dissociation constants for ligands binding to pheromone-binding proteins, using β-cyclodextrin as a solubilizer and transfer agent. The

Highly selective ruthenium metathesis catalysts for ethenolysis.

Renee M Thomas et al.

Journal of the American Chemical Society, 133(19), 7490-7496 (2011-04-23)

N-Aryl,N-alkyl N-heterocyclic carbene (NHC) ruthenium metathesis catalysts are highly selective toward the ethenolysis of methyl oleate, giving selectivity as high as 95% for the kinetic ethenolysis products over the thermodynamic self-metathesis products. The examples described herein represent some of the

A single-host fermentation process for the production of flavor lactones from non-hydroxylated fatty acids.

Eko Roy Marella et al.

Metabolic engineering, 61, 427-436 (2019-08-14)

Lactone flavors with fruity, milky, coconut, and other aromas are widely used in the food and fragrance industries. Lactones are produced by chemical synthesis or by biotransformation of plant-sourced hydroxy fatty acids. We established a novel method to produce flavor

High-level production of extracellular lipase by Yarrowia lipolytica mutants from methyl oleate.

Farshad Darvishi et al.

New biotechnology, 28(6), 756-760 (2011-02-18)

The yeast Yarrowia lipolytica degrades efficiently low-cost hydrophobic substrates for the production of various added-value products such as lipases. To obtain yeast strains producing high levels of extracellular lipase, Y. lipolytica DSM3286 was subjected to mutation using ethyl methanesulfonate (EMS)

Candida parapsilosis produces prostaglandins from exogenous arachidonic acid and OLE2 is not required for their synthesis.

Zsuzsanna Grózer et al.

Virulence, 6(1), 85-92 (2015-02-06)

Prostaglandins are C20 fatty acid metabolites with diverse biological functions. In mammalian cells, prostaglandins are produced from arachidonic acid (AA) via cyclooxygenases (COX1 and COX2). Although fungi do not possess cyclooxygenase homologues, several pathogenic species are able to produce prostaglandins from

[Effect of lecithin on the inhibitory efficiency of alpha-tocopherol during methyl oleate oxidation].

L I Mazaletskaia et al.

Biofizika, 55(1), 25-31 (2010-02-27)

It has been established that the effect of lecithin on the oxidation of methyl oleate depends on the rate of the free radical initiation: lecithin does not affect the reaction rate at high rates of radical initiation (the initiated oxidation)

Biodiesel synthesis from oil palm empty fruit bunch biochar derived heterogeneous solid catalyst using 4-benzenediazonium sulfonate.

Steven Lim et al.

Journal of hazardous materials, 390, 121532-121532 (2019-12-18)

In this research, biomass from oil palm empty fruit bunch was used as the carbon precursor and sulfonated by 4-benzenediazonium sulfonate (4-BDS) to produce solid acid catalyst. The as-synthesized catalysts were characterized and the performances were tested in esterification of

Synthesis of an amine-oleate derivative using an ionic liquid catalyst.

Atanu Biswas et al.

Journal of agricultural and food chemistry, 57(18), 8136-8141 (2009-09-02)

A facile (and environmentally friendly) reaction between epoxidized methyl oleate and aniline to produce an oleate-aniline adduct, without the formation of fatty amide, was discovered. This reaction was carried out neat, with a catalytic amount of an ionic liquid. No

A detailed identification study on high-temperature degradation products of oleic and linoleic acid methyl esters by GC-MS and GC-FTIR.

Olivier Berdeaux et al.

Chemistry and physics of lipids, 165(3), 338-347 (2012-03-20)

GC-MS and GC-FTIR were complementarily applied to identify oxidation compounds formed under frying conditions in methyl oleate and linoleate heated at 180°C. The study was focused on the compounds that originated through hydroperoxide scission that remain attached to the glyceridic

Satomi Hirano et al.

Colloids and surfaces. B, Biointerfaces, 94, 1-6 (2012-03-07)

Phospholipase D (PLD)-mediated hydrolysis of phosphatidylcholine (PC) in large unilamellar vesicles (LUVs) consisting of PC and either glycerol monooleate (GMO) or methyl oleate (MeO) were monitored in situ and in real time by using a choline oxidase-immobilized oxygen electrode. This

Ozonolysis of methyl oleate monolayers at the air-water interface: oxidation kinetics, reaction products and atmospheric implications.

Christian Pfrang et al.

Physical chemistry chemical physics : PCCP, 16(26), 13220-13228 (2014-05-30)

Ozonolysis of methyl oleate monolayers at the air-water interface results in surprisingly rapid loss of material through cleavage of the C=C bond and evaporation/dissolution of reaction products. We determine using neutron reflectometry a rate coefficient of (5.7 ± 0.9) ×

Extrudate versus powder silica alumina as support for Re₂O₇ catalyst in the metathesis of seed oil-derivatives - a comparison.

Bassie B Marvey

International journal of molecular sciences, 10(1), 213-220 (2009-04-01)

Self- and cross-metathesis of fatty acid methyl esters (FAMEs) was investigated using a silica alumina supported Re(2)O(7) catalyst. Although a 3 wt% Re(2)O(7)/SiO(2)-Al(2)O(3)/SnBu(4) is already active for the metathesis of unsaturated FAMEs, the results have shown that particle size of

Synthesis of renewable heterogeneous acid catalyst from oil palm empty fruit bunch for glycerol-free biodiesel production.

Wan-Ying Wong et al.

The Science of the total environment, 727, 138534-138534 (2020-04-26)

Interest in biodiesel research has escalated over the years due to dwindling fossil fuel reserves. The implementation of a carbon-based solid acid catalyst in biodiesel production eradicates the separation problems associated with homogeneous catalysis. However, its application in the glycerol-free
