摘　　要：设计并合成了 5个烷基苯系列共 1 6个“Y”形结构的新双叔胺化合物 ,通过元素分析、红外、核磁共振及质谱证明了其结构 .对硫酸的萃取实验结果表明 ,多数品种比常用萃取剂三辛胺在萃取效能上有较大提高 ,其中最佳者萃取率和抱酸量分别提高了 4 2 .1 %和 2 6.1 % .Sixteen new di tertiary amine compounds of five alkylbenzene series with the “Y” shape molecular structure have been designed and synthesized, their structures have been characterized by IR, 1H NMR, MS and elemental analyses. The results of applied experiments for extracting sulfuric acid indicate that most of these compounds are more efficient than trioctylamine (TOA), one of the most typical amine extracting agents, where the extraction percentage and the acid association capacity of the best one are 42.1% and 26.1% higher than those of TOA, respectively.
