米糠油复合型加脂剂的合成及应用

Synthetic Process of Compounded Fatliquor Based on Rice Bran Oil

以米糠油为原料进行酰胺化、酯化等反应制备复合型加脂剂，讨论了原料配比及催化剂用量、反应温度对产品质量的影响。表１。

Abstract Rice bran oil is basetreated with NaOH for 1～2 hr. The treated oil is reacted at 80～140℃ for 2～4 hrs, added with diacid at 90～120 ℃ , dehydrated under vacuum and esterified for 2～3 hrs. Then, it is neutralized with NaOH. The obytained product is combined with animal and vegetable oils, lanolin and other chemicals to produce the compounded fatliquor which is possessed of better filling properties and gives full and soft leathers.1 table,5 references
