- 摘要：
- The present invention relates to a process for the preparation of phosphoric acid, phosphorous acid and phosphonic acid aryl esters with alpha -methylbenzylphenoxy radicals, in which the reaction of phenols optionally substituted by C1 to C4-alkyl groups or of a phenol with styrene is carried out by addition of a phosphorus chloride intended for the further reaction as a catalyst and the further reaction is carried out with a phosphorus chloride, if appropriate in the presence of phosphorus pentachloride and if appropriate with the addition of a further phenol, at temperatures from 20 to 350 DEG C.
