耐溶媒纳滤膜在盐酸林可霉素母液回收中的应用

Application Experiment Study of SeLROTM Nanofiltration Membranes in Recovery Lincomycin Hydrochloride in Mothe Liquor

采用Hydrochem公司的SeLROTM耐溶媒纳滤膜及M104防爆型中试设备浓缩盐酸林可霉素丙酮母液至30万U/ml,将浓缩液重结晶,获得盐酸林可霉素成品。根据检验结果,盐酸林可霉素符合CP2000标准,另外可提高收率2%～4%,效益十分可观,应用前景广阔。

In this paper ,Lincomycn Hydrochloride acetone mothe liquor is condensed to 300000u/ml by SeIROTM resistant medium nanofiltration membranes produced by Hydroeherm company and middle equipment M104 which resistant explosion. After concertration recrystal,lincomycin Hydrochloride product was obtained.According to detection,Lincomcycin Hydroehloride quality live up to CP2000 standard. In addition, productivity raised by 2%-4%.Application prospect is comprehensive while result is very profitable.
