摘　　要：以茶油脱臭馏出物为原料,采用阳离子交换树脂催化酯化反应,然后将酯化产物进行三次分子蒸馏,逐步脱除脂肪酸和少量的其他杂质。通过正交试验法对分子蒸馏试验条件进行优化。结果表明,当蒸发温度为200℃,进料速率为4 m L/min,刮膜转速为150 r/min时,产物维生素E的纯度达到最高,为0.93%。应用高效液相色谱法对原料成分进行分析,建立了从原料到产品的维生素E含量分析方法,为生产维生素E提供技术参考。The deodorized distillate of camellia seed oil was used as the raw materials.The acidic exchange catalyzed esterification.Then,product esterified was separated by three-stage molecular distillation,and orthogonal experiments were introduced to conduct the third-stage distillation experiment,and was analyzed to find the preferred conditions that were distillation temperature 200℃,feed rate 4 m L/min and agitating speed 150 r/min,getting Vitamin E content 0.93%.A comprehensive analytical method was developed by HPLC,and a technical reference was provided for the production of Vitamin E.
