Modeling of reaction kinetics for transesterification of palm-based methyl esters with trimethylolpropane

Bioresour. Technol. 101(15) , 5877-84, (2010)

A mathematical model describing chemical kinetics of transesterification of palm-based methyl esters with trimethylolpropane has been developed. The model was developed by utilizing nonlinear regression method, which is an efficient and powerful way to determ...

Neurotoxin formation from pilot-scale incineration of synthetic ester turbine lubricants with a triaryl phosphate additive.

Arch. Toxicol. 70(8) , 508-9, (1996)

The high-temperature combustion of synthetic ester turbine engine lubricants has been performed by diluting the lubricant 5, 15, or 25% in diesel fuel and burning the mixture in a pilot-scale boiler facility. The effluent gas from this combustion system was c...

Biodegradation of a synthetic lubricant by Micrococcus roseus.

Appl. Environ. Microbiol. 59(4) , 1072-6, (1993)

A bacterium that was able to utilize Emkarate 1550 (E1550), a synthetic lubricant ester, as the sole source of carbon was isolated. The isolate was tentatively identified as Micrococcus roseus. The components of the E1550 ester, octanoate, decanoate, and 1,1,...

Long-term changes in rat social behavior following treatment with trimethylolpropane.

Neurotoxicol. Teratol. 20(3) , 307-16, (1998)

A potent convulsant, trimethylolpropane phosphate (TMPP), was evaluated for long-term effects on measures of social behaviors and anxiety in Long-Evans rats. Animals received three to four daily treatments of TMPP (0.1 mg/kg/ml) beginning at age 23 days in Ex...

Synthesis of X(Y)-(EO)(n)-OCH₃ type heterobifunctional and X(Y)-(EO)(n)-Z type heterotrifunctional poly(ethylene glycol)s.

Bioconjug. Chem. 22(3) , 518-22, (2011)

A synthetic route to prepare acetal-protected heterobifunctional poly(ethylene glycol), allyl(1-ethoxyethoxy)-PEG-OH (allyl(EE)-PEG-OH), was successfully established using a newly synthesized initiator, trimethylolpropane allyl (1-ethoxyethoxy) ether (TMPAEEE...

Synthesis of trimethylolpropane esters of oleic acid by Lipoprime 50T.

J. Ind. Microbiol. Biotechnol. 38(9) , 1561-6, (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 inve...

Dissociation constants for GABA(A) receptor antagonists determined with neuronal networks on microelectrode arrays.

J. Neurosci. Methods 173(2) , 183-92, (2008)

Changes in spontaneous spike activities from murine frontal cortex networks grown on microelectrode arrays were used to determine the dissociation constants of three GABA(A) antagonists: gabazine, bicuculline, and trimethylolpropane phosphate (TMPP). Networks...
