The reaction is carried out in the presence of a ruthenium catalyst, and the reaction conditions include a relatively low temperature, preferably around 0°C to room temperature, in order to suppress the polymerization of the raw alcohol under pressurized carbon dioxide. Adopted. As the ruthenium catalyst, its halide or carbonyl complex is used, and it is desirable to use an organic base such as a tertiary amine as a co-catalyst. Carbon dioxide pressurization is usually 1 to 50
Pressurization of about atmospheric pressure is used.
