Abstract
A method of making oleochemical oil-based polyols by mixing an acid activated or acid leached clay, an epoxidized oleochemical oil, alcohol, and acid activated or acid leached clay so the epoxidized oleochemical oil reacts with said alcohol to form a oleochemical oil-based polyol, filtering out said clay, stripping off any excess alcohol, and recovering the oleochemical oil-based polyol.
