| 摘 要： | 研究了用二（２－乙基己基）磷酸（Ｐ２０４）作萃取剂，从毛发水解生产胱氨酸的二次母液中提取亮氨酸和异亮氨酸的方法和条件。研究表明，在常温条件下，水相初始ｐＨ为４．０时，用３０％的Ｐ２０４（体积分数）正庚烷溶液，萃取相比为１，可萃取出水相中近７０％的亮氨酸和异亮氨酸。

| Abstract: | The method and its conditions of extracting leucine and isoleucine,with di(2 ethylhexyl)phosphonic acid(P204) as catalyst,from secondary mother liquor obtained from hydrolyzing animal hair in the process of producing cystine is investigated.The result shows that about 70% of leucine and isoleucine contained in water phase can be extracted under ordinary temperature,when initial pH value of water phase is 4,P204/ n heptane=0.3 and the ratio of extract phase to water is equal to 1. |
