Abstract

Process for drying a mixture containing at least one hydrocarbon, hydrochloric acid and water, characterised in that it is placed in contact with a desiccant chosen from (i) anhydrous metal sulphates, chlorides or perchlorates or (ii) phosphorus pentoxide until the desiccant has retained most of the water. This is applied to the synthesis of chloromethanes to dry the methyl chloride leaving the head of the CH3Cl/higher chloromethanes separating column.
