A process for preparing a hydroxy functional vegetable oil having an acid number of less than about 1 mg KOH/g is provided. The process comprises contacting a raw vegetable oil with hydrogen peroxide and an organic acid in the presence of water for a sufficient period of time, at a sufficient temperature, and at a sufficient pressure to form hydroxyl groups from unsaturated moieties in the vegetable oil. Thereafter separating any volatiles from the hydroxy functional vegetable oil, followed by heating of the product at a temperature of at least approximately 175°C under a vacuum, wherein the organic acid has from 1 to 3 carbon atoms. |
