| 摘 要： | 将元宝枫油制成混合脂肪酸乙酯,分别利用多级分子蒸馏提纯和分子蒸馏与尿素包合法相结合提纯神经酸乙酯得到高含量的神经酸乙酯产品。六级分子蒸馏直接提纯神经酸乙酯,得到神经酸乙酯含量为78.35%的产品。二级分子蒸馏与尿素包合法相结合时,分子蒸馏脱除甾醇、维生素E、C16、C18、C20及部分C22脂肪酸乙酯,得到神经酸乙酯与芥酸乙酯比例为1∶1的初级产品,再在m(脂肪酸乙酯)∶m(尿素)∶V(甲醇)为1∶5∶35、包合温度35℃、包合时间8 h条件下,经过二次尿素包合处理,可得到神经酸乙酯含量为66.21%的产品。

| Abstract: | The fatty acid ethyl esters were prepared from Acer truncatum Bunge seed oil,and then the separation process of nervonic acid ethyl ester by molecular distillation directly or combination of molecular distillation and urea-inclusion method was studied.The content of nervonic acid ethyl ester reached 78.35% by six-step molecular distillation.When the molecular distillation and urea-inclusion were combined to separate nervonic acid,two-step molecular distillation was used to separate the sterols,VE,C16 fatty ... |
