PRODUCTION OF METHYL CHLORIDE

摘要

PURPOSE:To provide a process for the vapor-phase reaction of methanol and hydrogen chloride in the presence of a new catalyst to enable the production of methyl chloride in high conversion and selectivity even at a relatively low temperature. CONSTITUTION:Methyl chloride is produced by reacting methanol with hydrogen chloride in vapor phase in the presence of a titanium oxide catalyst which may be incorporated with an oxide of a metal such as zinc and chromium. High methanol conversion and high methyl chloride selectivity can be achieved even at a temperature as low as about 200-250 deg.C.
