Abstract: The present invention discloses a process for the production of a fatty acid/L-carnitine derivative, whereby the educts are reacted in the presence of monochloroacetic acid.

Abstract: There are provided novel thermally stable surfactants for use with fillers in the preparation of polymer composites and nanocomposites. Typically, surfactants of the invention are urethanes, ureas or esters of thiocarbamic acid having a hydrocarbyl group of from 10 to 50 carbons and optionally including an ionizable or charged group (e.g., carboxyl group or quaternary amine). Thus, there are provided surfactants having Formula I: wherein the variables are as defined herein. Further provided are methods of making thermally stable surfactants and compositions, including composites and nanocomposites, using fillers coated with the surfactants.

Abstract: A process for the production of esters, comprising allowing an olefin, carbon monoxide and an alcohol to react in the presence of hydrogen fluoride, in which the esters can be produced at high yields at a low temperature for a short period of time, the esters can be easily separated from a reaction solution, hydrogen fluoride can be recycled, the esters can be produced at a low cost, a mixture of esters can be easily produced, the kinetic viscosity of the mixture of the esters can be easily adjusted and the coloring of, and an increase in the viscosity of, the esters can be prevented.

Abstract: Hydrocarboxyalkylation of .alpha.,.omega.-dienes with carbon monoxide and an alcohol in the presence of a cobalt compound and a tertiary amine gives .omega.-enecarboxylic acid esters with high selectivity and in good yields.

Abstract: A method for preparing .alpha., .beta.-unsaturated carboxylic acids of the formulaR.sub.1 (R.sub.2)C.dbd.C(R.sub.3)CO.sub.2 Hwhere R.sub.1 to R.sub.3 can be hydrogen, fluorine, alkyl, or alkyl containing fluorine, but at least one of R.sub.1 to R.sub.3 is fluorine or alkyl containing fluorine. The method involves reacting an alkenyl halide containing fluorine having the general formulaR.sub.1 (R.sub.2)C.dbd.C(R.sub.3)Xwhere R.sub.1 to R.sub.3 are the same as above, and X is chlorine, bromine, or iodine with carbon dioxide in an aprotic polar organic solvent and in the presence of activated zinc. The activated zinc is activated by pretreatment with a mineral acid or acetic acid. At least one cation is present during the reaction which is an alkali metal ion, alkaline earth metal ion or ammonium ion. The cation is present in an amount of 0.01 to 50 gram atoms per one mol of alkenyl halide containig fluorine. The resulting product is hydrolyzed.
