【Abstract】 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.更多还原
