The kinetics of addition of acetic acid to epichlorohydrin carried out in the presence of both the reaction product and chromium(III) acetate catalyst have been studied. At an equimolar ratio of reagents the dilution of the reacting mixture with the reaction product has been found not to affect the reaction order. The presence of product in the starting mixture, as well as temperature increase, considerably reduces the selectivity of reaction. Side reactions of epichlorohydrin are activated. Activation energy, enthalpy and entropy of the reaction all decrease in the presence of reaction product. © 2001 Society of Chemical Industry
