PURPOSE:To advantageously obtain the titled compound without using a corrosive substance, expensive noble metal and consuming unrecoverable reaction accelerator, by reacting a carboxylic acid anhydride with hydrogen in the presence of a specific catalyst. CONSTITUTION:A carboxylic acid anhydride is reacted with hydrogen in the presence of a catalyst substantially consisting of one or more metals selected from nickel, iron and cobalt and/or a compound of one or more such metals, specifically, e.g. nickel chloride, iron carbonate, cobalt oxide, etc., used by preferably supporting on a carrier at 60-450 deg.C under 1-250atm to afford the aimed compound. The molar ratio of the hydrogen to the carboxylic acid anhydride is within the range of 0.01-150, preferably 0.1-100. If the supported type catalyst is used, separation of the catalyst and the product and recovery operation of the catalyst are not required. |
