Abstract
PURPOSE: A mixture containing a catalyst, which results from the reaction between butadiene, carbon monoxide and an alcohol in the presence of a cobalt catalyst is treated with an oxygen-containing gas to stabilize the catalyst to collect the titled substance of no color by no use of a catalyst recovering unit.
CONSTITUTION: The reaction between butadiene, carbon monoxide, and an alcohol is conducted in the presence of a catalyst of cobalt carbonyl or cobalt carbonyl complex to give the reaction mixture containing 3-pentenoic ester and cobalt carbonyl or cobalt carbonyl complex. The reaction mixture is treated with an oxygen-containing gas, preferably air, in a range from room temperature to 150°C and distilled or distilled under the oxygen treatment to collect the objective compound.
