| Abstract: | Octadecyl oleate was synthesized by esterification of oleic acid and octadecyl alcohol with NaHSO 4/Al 2O 3 catalyst.The effects of reaction conditions were discussed,such as the quantity of catalyst,molar ratio of octadecyl alcohol to oleic acid,reaction temperature and reaction time.The optimum reaction conditions have been using determined.The yield of octadecyl oleate was over 91%.The results showed that activated carbon to decolorize technical product could decrease obviously the color of octadecyl oleate. |
