Abstract

Procédé de préparation de l'acide méthacrylique, de son nitrile et de ses esters, à partir respectivement de l'acide propionique, de son nitrile et de ses esters, par réaction avec le méthylal en présence d'un catalyseur, conformément au brevet principal. On effectue la réaction en présence de bioxyde de zirconium. L'utilisation de bioxyde de zirconium comme catalyseur a permis d'abaisser les températures de réaction d'environ 150 à 200 degrés C par rapport à l'emploi de l'alumine.
