Abstract

It was found that the molecular weights of adducts in the acid-catalyzed reactions of epichlorohydrin with alcohols obey the Weibull-Nycander distribution but not the Flory distribution. The distribution constants (C= ki⁄ k 0) were found to be smaller than 1, indicating that the reaction rate of the initial stage (k 0), ie, the reaction of epichlorohydrin with a starting alcohol, is greater than the rates of the later stages (ki), ie, the reactions of ...
