<p>Two-step process for the preparation of glycidyl compounds having a low proportion of hydrolysable halogen by reacting chlorine- or bromine-substituted bisphenols, mono- or dicarboxylic acids, mono- or diamines or cyanuric acid with an epihalohydrin, more than 1 and at most 1.8 equivalents of epihalohydrin being used per equivalent of reactive H atom, the halohydrin compounds obtained in the first step being freed from excess epihalohydrin by means of azeotropic distillation and then being washed by stripping with water, and in a second step dehydrohalogenation of the halohydrin compounds being carried out in an inert, substantially water-immiscible organic solvent.</p> |
