多乙烯多胺萃取工艺研究

The Technological Research on Extraction of Polyethylene Polyamines

以环己酮和正丁醇为溶剂，对多乙烯多胺萃取工艺进行了研究。最佳工艺条件为：酮胺比３∶１ ，醇酮比３∶１ ，萃取时间１０ｍｉｎ ，萃取次数２ 次，多胺溶液浓度０ ．１５ｇ·ｍ Ｌ－ １ ，多胺萃取收率达到９５ ％ 以上。

Cyclohexanone and n-butanol as solvents,the process has been investigated to extract polyethylene polyamines.The optimum production conditions are as follows:n(cyclohexanone)∶n(polyethylene polyamines) = 3∶1,10min,concentration of polyethylene polyamines solution is 0.15g·mL -1 .Under the optinum conditions,the extraction yield of polyethylene polyamines can reach 95%.
