et al.

Abstract: Vegetable oils‐based polyols prepared by epoxidation‐hydroxylation often have the phenomenon of the coexistence of epoxy and hydroxyl groups due to different ring‐opening degrees. The acylation method recommended by the American Society of Testing Materials (ASTM) standard (D1957‐86) and the Association of Official Analytical Chemists (AOAC) standard (965.32) is applicable only to fatty alcohols in oils and fats and their derivatives but not to vegetable oils‐based polyols since the residual epoxy groups in ve… Show more
