Patent Title: METHOD OF MAKING POLYOL COMPOSITIONS

“Gist”: Single-pot synthesis of natural-oil polyols by Prilezhaev oxidation and subsequent ring-opening of unsaturated triglycerids.

Why it is interesting: According to this invention NOPs can be prepared by reacting unsaturated natural oils with a peroxy acid. The epoxidation followed by ring opening occurs in a single reaction sequence.  The peroxy acid is first prepared by reacting a small organic acid with hydrogen peroxide. In the examples high oleic algae oils are used together with e.g. oxidized lactic acid.  The reaction has the advantage of being more rapid and using less toxic ingredients than current systems to prepare NOPs.
