Abstract

PURPOSE: To prepare the titled substance without troubles such as corrosion of the reaction apparatus, by reacting methanol with CO in the presence of a catalyst composed of Rh or Pt metal and a rare earth metal oxide and pref. pretreated with CO-containing gas.
CONSTITUTION: In the preparation of the titled substance by the reaction of methanol with CO, a composition composed of Rh or Pt metal and a rare earth metal oxide is used as the reaction catalyst. The weight ratio of the rare earth metal oxide to metallic Rh or Pt used as the substrate is 0.1W100. The mixture of both components may be formed as it is, or supported on a carrier. The catalytic activity of the above catalyst can be improved by pretreating with a CO-containing gas or a compound capable of producing CO on the surface of the catalyst (e.g. methanol) prior to the reaction.
EFFECT: The purification, etc. of the product can be carried out easily since halogen compounds are not used in the reaction.
