Reaction Conditions

Reaction Steps

P-phenoxybenzotrichloride (288 parts) was added to 182 parts of p-phenoxybenzoic acid, with mixing. The mixture was allowed to stand at ambient temperature for about 16 hours, then heated, over a period of about 4 hours, to a temperature of about 140° C., at which point HCl evolution was detected. The mixture was maintained at a temperature of between about 112° and 140° C. for an additional 21 hours, then cooled and analyzed by gas chromatographic techniques. Analysis indicated a 73% yield of p-phenoxybenzoylchloride based on the starting materials.
