Abstract
In this paper, kinetic of esterification reaction of tetrahydric alcohols(pentaerythritol) with branched-chain fatty acid(2-ethyl-heonoic acid) was studied. The kinetic model of the reaction was established, and the data-fitting curve carried out according to the experimental data. The order of the complex reaction was concluded by trial method and overall reaction model was established as well as the analytical solution, which provided a theoretical basis for further industrial application.
