Utility of nicotinoyl derivatives in structural studies of mono- and diacylglycerols by gas chromatography/mass spectrometry. Part 3 - Application to acylglycerols with methyl branchings and epoxy and cyclopropyl rings

Mono- and diacylglycerols with methyl branches and epoxy and cyclopropyl rings were synthesized and, subsequently converted into their nicotinoyl derivatives by reaction with nicotinic acid and N,N'-dicyclohexylcarbodiimide in the presence of N,N-dimethyl-4-aminopyridine. The resulting nicotinoyl derivatives were examined by gas chromatography/mass spectrometry (GC/MS). Their electron impact mass spectra reveal the structures of mono- and diacylglycerols in greater detail than the mass spectra of other acylglycerol derivatives. The positions of methyl branches and epoxy and cyclopropyl rings in mono- and diacylglycerols can be determined from characteristic features in the fragmentation patterns, which are caused by radical-induced cleavage of the alkyl chains following random hydrogen abstraction by the pyridine nucleus. These results offer a promising; approach to the structural analysis of glycerophospholipids by means of GC/MS.

Cellulose fatty acid esters as sustainable film materials-effect of side chain structure on barrier and mechanical properties

Cellulose is mainly utilized by industry for paper and packaging materials. Due to ecological awareness this biopolymer has recently received an increasing amount of attention as a renewable alternative for replacing traditional oil based products. In this work, hydrophobic cellulose based materials were prepared by acylation of cellulose with tall oil fatty acid based saturated, unsaturated and branched fatty acids. Films were prepared by casting, and their oxygen and water vapour permeabilities as well as mechanical and thermal properties were characterized. Unsaturation and branching had a significant effect on the properties of the films. Comparing these materials with already existing commercial products showed that fatty acid modification of cellulose yields films with increased thermal stability, low water vapour transmission rates and enhanced tensile and elastic properties.

personal care products incorporating cellulosic fatty acid esters

A personal care product composition containing a long chain fatty acid cellulose ester (LCCE) having a degree of substitution greater than about 1.0 of an ester substituent or residue from fatty acids having from 6 to 18 carbon atoms wherein the LCCE is soluble in at least one cosmetically acceptable solvent selected from the group consisting of hydrocarbons, alkyl esters, fats and oils, fatty acids, fatty alcohols, and silicone oils.
