摘要
对两种新型双叔胺类萃取剂进行萃取应用的研究，考察萃取温度、稀释剂、初始酸浓度、萃取剂浓度、相比等几个因素对萃取效果的影响．通过与三辛胺对硫酸溶液做萃取效果对比试验后得出：４，４′亚甲基双（２乙基Ｎ，Ｎ二辛基苯胺）的萃取效果较好，它的抱酸量比三辛胺提高了３３．５％．
? Methylene-bis(2-ethyl-N,N-dialkylaniline)(alkyl:octyl,hexyl) is a new type of extractant. Their application in extracting sulfuric acid was investigated. The influence of extraction temperature, diluent, initial acid concentration, extractant concentration and phase ratio on extraction was discussed. Compared with extracting sulfuric acid by trioctylamine, 4,4′ methylene bis(2 ethyl N,N dioctylaniline) has a satisfactory result. Its extraction efficiency increases by 33.5 %.
