Title
(DE) VERBESSERTES VERFAHREN ZUR HERSTELLUNG VON CHLORESSIGSÄURE PHENYLESTER
(EN) IMPROVED PROCESS FOR PREPARING PHENYL CHLOROACETATE
(FR) PROCEDE AMELIORE DE PREPARATION DE CHLOROACETATE DE PHENYLE
Abstract
(EN)
An improved solvent-free process for preparing phenyl chloroacetate in which chloroacetyl chloride is reacted with phenol in the presence of a catalytic amount of an organic ammonium salt, phosphonium salt, amine, phosphine or amide, is described.

(FR)
L'invention décrit un procédé amélioré exempt de solvant, servant à préparer du chloroacétate de phényle, selon lequel on soumet un chlorure de chloroacétyle à une réaction avec du phénol en présence d'une quantité catalytique d'un sel d'ammonium organique, d'un sel de phosphonium, d'une amine, d'une phosphine ou d'un amide.
