ABSTRACT OF THE DISCLOSURE A cobalt component is separated from a hydroesterification reaction mixture obtained by reacting a polyhydric alcohol with an olefin and carbon monoxide in the presence of a cobalt carbonyl complex and a pyridine base, by contacting (a) pyridine or ?-picoline and (b) water with said reaction mixture containing the cobalt compo- nent and product fatty acid ester of polyhydric alcohol to separate it into two phases a phase containing the fatty acid ester of polyhydric alcohol and a phase containing a cobalt component. In the process, the ratio of pyridine or ?-picoline is 0.2 to 10 parts by weight to said fatty acid ester of polyhydric alcohol and the ratio of water is 0.05 to 10 parts by weight to pyridine or ? - picoline. -19-
