摘要：
In the method of manufacturing liquid polyol esters of carboxylic acid by making an olefin having 3 or more carbon atoms, carbon monoxide and polyhydric alcohol react with one another in the presence of a cobalt compound catalyst, the steps comprising heating the thus reacted mixture to distill out unreacted olefin and so forth, thereafter cooling the distillation residue and separating it into the ester of polyhydric alcohol and the cobalt compound.
