Lipase-Mediated Syntheses of Trimethylolpropane-Based Biolubricant and Cyclic Carbonate

Biocatalysis is considered as benign and efficient alternative to chemical catalysis for organic syntheses. Lipases are the most versatile biological catalysts implemented so far with great potential for production of different chemicals and materials in nonconventional reaction media. This thesis presents investigations on lipase catalyzed esterification and transesterification reactions in so...

Tissue distribution, metabolism, and clearance of the convulsant trimethylolpropane phosphate in rats.

The distribution, metabolism, and clearance of trimethylolpropane phosphate (TMPP), a potent, bicyclophosphate, gamma-aminobutyric acid-ergic convulsant, were studied in male Fischer-344 rats. Intraperitoneal administration of TMPP was compared with oral gavage with respect to rates of absorption, distribution, and clearance. Distribution of TMPP to major body tissues was evaluated for the firs...

Repeated exposure to trimethylolpropane phosphate induces central nervous system sensitization and facilitates electrical kindling.

Trimethylolpropane phosphate (TMPP), pentylenetetrazol (PTZ) and N-methyl-beta-carboline-3-carboxamide (FG-7142) were evaluated and compared for facilitation of electrical kindling in freely moving rats. Stimulating/recording electrodes were implanted in the left amygdala (LAD), right amygdala (RAD) and left bed nucleus (LBN) of the stria terminalis. TMPP (0.275 mg/kg), PTZ (20 mg/kg), FG-7142 ...

Tribological Characteristics of Calophyllum inophyllum–Based TMP (Trimethylolpropane) Ester as Energy-Saving and Biodegradable Lubricant

Palm oil derived trimethylolpropane triesters synthetic lubricants and usage in industrial metalworking fluid.

Trimethylolpropane triesters are biodegradable synthetic lubricant base oil alternative to mineral oils, polyalphaolefins and diesters. These oils can be produced from trimethylolpropane (TMP) and fatty acid methyl esters via chemical or enzymatic catalyzed synthesis methods. In the present study, a commercial palm oil derived winter grade biodiesel (ME18) was evaluated as a viable and sustaina...
