Summary for Patent: RE45868
| Title: | Methods of preparing hydroxy functional vegetable oils |
| Abstract: | There is disclosed a process for hydroxylating vegetable oils to create polyols suitable for use in polymer processes, particularly polyurethane processes. The process includes contacting a vegetable oil with hydrogen peroxide and an organic acid having 1-3 carbon atoms under conditions sufficient to oxidize carbon to carbon double bonds found in the vegetable oil. There is also disclosed a vegetable oil based polyol having an acid number of 2.0 mg KOH/g or less. The polyol contains 0.1% w/w or less water, 0.1% w/w or less of the organic acid used to prepare the polyol, and triglyceride groups having fatty acid moieties ranging from C.sub.16 to C.sub.18. The fatty acid moieties contain pendant carboxylate groups having from 1 to 3 carbon atoms. |
