Abstract
A process for the production of a high-performance hybrid polyol ester having excellent compatibility with hydrofluorocarbons which are regarded as the most likely refrigerant and having excellent resistance to hydrolysis which esters are liable to undergo, the polyol ester having a plurality of branched fatty acid residues at least one of which has a different number of carbon atoms from that of the other branched fatty acid residue or those of the other branched fatty acid residues, the process comprising reacting at least two kinds of olefins having different numbers of carbon atoms, carbon monoxide and a polyhydric alcohol in the presence of hydrogen fluoride.
