摘要
采用KOCH公司SelROTM耐溶媒纳滤膜浓缩回收6-APA母液,将浓缩液重结晶,可获得6-氨基青霉烷酸(6-APA),根据检验结果,6-氨基青霉烷酸符合厂订标准,收率可以提高2%～3%,效益十分可观,应用前景十分广阔。
In this paper, mothe liquor is condensed by SelRO^TM resistant medium nanofiltration membranes produced by koch company. After concertration recrystal, 6-APA product was obtained. According detection. 6-APA quality live up to company standard. In addition, productivity raised by 2%-3%. Application prospect is comprehensive while result is very profitable.
