摘要:This invention relates to a process for preparing phenylacetic acid. In particular, the present invention relates to a catalytic process for the synthesis of the alkaline salts of phenylacetic acid by carbonylation of benzyl halides in a diphase system in the presence of cobalt carbonyl complexes. More particularly, the present invention relates to a process for preparing alkaline salts of phenylacetic acid by reacting a benzyl halide selected from chloride and bromide with carbon monoxide in the presence of a catalyst consisting in a salt of cobalt hydrocarbonyl, characterized in that the reaction is conducted in an aqueous/organic diphase system consisting of (a) an aqueous solution of an inorganic alkaline base, and (b) the benzyl halide in an organic solvent, in the presence of a catalyst system composed by a quaternary alkylammonium salt and by a cobalt hydrocarbonyl salt, at atmospheric pressure and at a temperature ranging from 20 DEG to 70 DEG C about.

摘要:PROCESS FOR THE SYNTHESIS OF PHENYLACETIC ACID BY CARBONYLATION OF BENZYL CHLORIDE. THE PROCESS COMPRISES REACTING BENZYL CHLORIDE AND CARBON MONOXIDE UNDER ATMOSPHERIC PRESSURE, AT TEMPERATURES FROM 20* TO 80*C. IN A WATER-METHANOL MEDIUM CONTAINING UP TO 35% WATER, USING A CATALYST MIXTURE CONSISTING OF A COBALT SALT, IN IRON-MANGANESE ALLOY AND A SUPLPHURATED PROMOTING AGENT. CALCIUM OXIDE IS USED AS A NEUTRALIZING AGENT. THE CALCIUM SALT OBTAINED IS TREATED WITH A STRONG MINERAL ACID TO FREE THE PHENYLACETIC ACID.
