Process for the preparation of compounds of the formula (A) wherein Hal represents chlorine, bromine or iodine and preferably chlorine, wherein Ra represents a residue comprising one or more additional groups of the formula (A') from compounds (III) wherein R2 represents a residue comprising one or more additional groups of the formula (VI) by reaction with gaseous hydrogen halide in the presence of a catalytic amount of an organic acid; process for the preparation of epoxy compounds starting from the reaction (I), and epoxy resins obtained via this process showing a significantly lower content of intermingled halogen.

On décrit un procédé de préparation de composés de formule (A). Dans cette formule Hal représente chlore, brome ou iode, de préférence chlore et R¿a? représente un reste comprenant un ou plusieurs groupes additionnels de formule (A'), provenant des composés de formule (III) dans laquelle R¿2? représente un reste comprenant un ou plusieurs groupes additionnels de formule (IV) par réaction avec un halogénure d'hydrogène gazeux en présence d'une quantité catalytique d'un acide organique; le procédé de préparation de composés époxydiques commençant avec la réaction (I). Cette invention concerne également des résines époxydiques obtenues à l'aide de ce procédé qui se caractérisent par une teneur sensiblement inférieure en halogène entremêlé.
