Abstract

La présente invention a pour objet un procédé de préparation de l'acide difluoroacétique, ses sels ou ses esters. Le procédé de l'invention, de préparation de l'acide difluoroacétique, ses sels ou ses esters est caractérisé par le fait qu'il comprend la réaction en présence d'eau, d'un sel apportant un anion fluorure et de l'acide acétique mono- ou dihalogéné, sous forme acide, salifiée ou estérifiée ; au moins un atome d'halogène étant différent de l'atome de fluor.
