Abstract
In an improved process for preparing chlorinated phenol by the reaction of molten phenol with chlorine in the presence of a Friedel-Crafts catalyst, the improvement comprises adding to the molten chlorinated phenol product, immediately on completion of the chlorination process, at least 0.5 weight percent of a glycol ether thereby inhibiting dioxin formation, inhibiting decomposition of the technical grade chlorinated phenol and most importantly, imparting mold release properties to the final product which is cast in corrosion-resistant molds, preferably stainless steel or plastic-lined steel molds.
