摘要： Carbon tetrachloride, which is a material of low value and may be banned due to the problem of the destructiveness against the stratospheric ozone layer, can be efficiently utilized in the preparation of more useful methyl chloride by a catalytic vapor-phase reaction in a vapor mixture of carbon tetrachloride, methyl alcohol and water. The solid catalyst with which the vapor mixture is contacted at 150.degree. to 250.degree. C. is, for example, a zinc chloride catalyst supported on an active carbon carrier. The conversion of carbon tetrachloride is almost 100% when the contacting time is 10 to 20 seconds.
