PURPOSE:To obtain the subject compound in high yield at a low cost by reacting methyl alcohol in the vapor phase in the presence of a catalyst prepared by supporting copper chloride on metallic silicon. CONSTITUTION:For example, metallic silicon is added to an aqueous solution of ammonia containing copper chloride dissolved therein, etc., and the solvent is then evaporated by heating, etc., to provide a supported catalyst, which is subsequently pretreated in a gas stream, such as hydrogen. Methanol vapor is then brought into contact with the aforementioned pretreated supported catalyst (the contact time is 20000-1000hr<-1> gas space velocity at ordinary temperature under ordinary pressure) and reacted at 180-300 deg.C under ordinary or higher pressure by a fixed bed method to afford the objective compound. |
