  • Drying alkyl halides
    Patent number: 4307260
    Abstract: After quenching the effluent gas from a methanol hydrochlorination reactor to condense most of the water and remove excess HCl, the wet (saturated) methyl chloride is mixed with hydrogen chloride to provide a gas mixture having a methyl chloride:HCl ratio of from about 0.4:1 to about 4:1. This mixture is then contacted with cold (-16.degree. to -21.degree. C.) concentrated (50 to 59%) aqeous hydrochloric acid to remove the water to a low level. Additionally an undesirable by-product, dimethylether, is removed along with the water. Alternatively the wet gas mixture may be cooled to that same temperature by passing over cooling coils, or other convenient means, to remove the water.
