A study of the hydrochlorination of glycerol. In the current conditions, the development of alternative technologies for the synthesis of epochlorohydrin has become very relevant. Such technologies include a process based on the hydrochlorination of glycerol, especially since in recent years the chemical products market has been saturated with glycerol, a waste product of biodiesel production. However, the development of such technology requires the solution of a number of physico-chemical problems related to the hydrochlorination of glycerin and its chlorohydrides, dehydrochlorination of highly concentrated solutions of glycerin dichlorohydrins, as well as the establishment of the kinetics of the reactions of glycerol and esterification of acetic acid. In particular, we can talk about the effect of water as a solvent on the rate of reactions. This is all the more important because the data presented in the literature on the kinetics of hydrochlorination reactions of glycerin and its chlorohydrins are contradictory and inadequately describe the process over the operating temperature and concentration ranges. It can be assumed that understanding the physical chemistry of such processes and determining the characteristics of the kinetics of the reactions occurring during the production of epichlorohydrin from glycerin will provide an opportunity to choose the optimal conditions for the implementation of the process, including the type of reactors, operating temperatures, initial concentrations, proportions of reagents, etc. Keywords: Glycerin, hydrochlorination, chlorohydrides, epichlorohydrin.
