Patent ID: 8350070

Claim:
A process of preparing a hydroxy functional soybean oil, the process comprising: (A) providing a reactor; (B) adding a raw soybean oil and an organic acid having 1 to 3 carbon atoms to the reactor to form an organic phase and an aqueous phase; (C) heating the organic phase and the aqueous phase to about 50 to 135° C. with agitation generating a hot mixture; (D) metering a 35 to 70% weight/weight of hydrogen peroxide/water to the hot mixture of (C) generating a reaction mixture; (E) heating the reaction mixture in a range of 50 to 135° C. for about 1 to 24 hours; (F) stripping off the bulk of the organic acid, water and other low boilers at or below 150° C. and at a negative pressure that does not exceed 60 mmHg until the reaction mixture tests for an acid number of about 4.0 mg KOH/g or less.
