摘要
Abstract
In a stirred tank reactor,solid acid catalyst was used to catalyze the esterification of glycerol and butyric acid to prepare monoglyceride.The effects of reaction temperature,reaction time,and catalyst dosage on the reac-tion process were investigated.We studied the chemical equilibrium and reaction rate of glycerol and butyric acid esterification to produce monoglyceride butyrate.A kinetic model for second-order reversible reactions was estab-lished based on experimental results.The results showed that the chemical equilibrium constant for synthesizing monoglycerides increased with temperature,and the variation followed the Van't Hoff equation.The reaction was endothermic.The reaction rate constants for esterification,hydrolysis,and esterification of butyric acid glycerides with 2％catalyst by mass of butyric acid satisfied the Arrhenius equation,and the corresponding activation energies were 60.1,51.2,and 63.3 kJ·mol-1,respectively.关键词
