Characterization of Esters of fatty Acids and Dicarboxylic Acids with Guerbet Alcohols
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 dies...
متن کاملSeparation and quantitation of free fatty acids and fatty acid methyl esters by reverse phase high pressure liquid chromatography.
Reverse phase high pressure liquid chromatography (HPLC) on octadecylsilyl columns separates mixtures of either free fatty acids or fatty acid methyl esters prepared from mammalian tissue phospholipids. Acetonitrile-water mixtures are used for the elution of esters. Aqueous phosphoric acid is substituted for water for the separation of the free acids. Unsaturated compounds are detected and quan...
متن کاملSynthesis 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 کاملSemi-automated micro-scale extraction apparatus for assay of free fatty acids in plasma.
We describe the use of a semi-automated micro-scale extraction apparatus as applied to the assay of free fatty acids in plasma. With it, a smaller plasma sample is required, disposable glassware can replace acid-washed glassware, and the number of samples that one technican can assay per day is increased fivefold. Theroretically, this apparatus can be applied to all assay procedures requiring o...
