Study of the reaction of olefins with acetic acid
Abstract
The purpose of this work is to study the esterification of liquid olefins with acetic acid in the presence of catalysts and to study the structure and properties of the synthesized saturated esters. 1-Hexene, 2-methyl-1-pentene, 2-ethyl-1-pentene, 3-methyl-1-pentene, and 3-methyl-2-pentene were used as liquid olefins and acid catalysts were used as catalysts for the esterification reaction: H2SO4 and HCl. The influence of various factors (the nature of the catalysts, the relative activity of olefins and temperature a) on the rate of the esterification reaction was studied. It has been shown that the reaction rate is much higher in the presence of sulfuric acid than in HCl. It has been established that in the esterification of olefins with acetic acid, with an increase in the length of the side aliphatic substituent of 2-methyl-1-pentene olefins on 2-ethyl-1-pentene, the rate of the ester formation reaction decreases. The mechanisms of esterification reactions are presented. A basic technological scheme for the production of esters was proposed.
