摘要：The reactions involved in the industrial production of epichlorohydrin from dichloro-propanols (DCP, including 1,3-dichloro-2-propanol and 2-3-dichloro-1-propanlol) have been kinetically investigated. The kinetics of dehydrochlorination of DCP has been studied in the presence of caustic soda, by potentiometric techniques. The kinetic parameters of the reactions have been determined. The epichlorohydrin hydrolysis has been studied by measuring the decrease of the reagents during the time using titration. The whole study indicate that both dehydrochlorination and hydrolysis reaction can be considered as second order kinetic reaction. It is also indicated that the kinetic constant for dehydrochlorination reaction is far bigger than that for hydrolysis reaction in the same conditions.
