Flow activation quantities of trimethylolpropane ester.
Journal of The Japan Petroleum Institute, 1982 The flow activation quantities of eight trimethylolpropane esters and two mixtures were experimentally determined at 313.2K. The relation between activation quantities and molecular structures of these esters was discussed. The activation quantities of the physical mixtures were compared with those of the corresponding "chemical" mixtures of the same ...

Synthesis of trimethylolpropane esters of oleic acid by Lipoprime 50T
Journal of Industrial Microbiology & Biotechnology, 2011 The ability of the commercial lipolytic enzyme Lipoprime 50T to catalyze the biotechnologically important synthesis of the biodegradable and environmentally acceptable trimethylolpropane (2-ethyl-2-(hydroxymethyl)-1,3-propanediol) ester of oleic acid was investigated. Simple and accurate thin-layer chromatography and computer analysis methods were used
