【摘要】 本文主要研究了正辛醇、正己醇和氟代醇3种萃取剂对NaOH的萃取平衡。实验表明,3种萃取剂的萃取平衡曲线均随水相浓度而上升,氟代醇的萃取效率较二者好。三者均能将NaAlO2溶液中游离的NaOH萃入油相,油相NaOH浓度可达34g.L-1。更多还原

【Abstract】 The equilibrium of extraction on sodium hydroxide by l-octanol,hexanol and fluorintaed alcohol was studied in this paper.The results showed that three equilibrium curves of extraction were asceneding with the increasing of concentration of sodium aluminate in the watere,the extracting efficiency of fluorintaed alcohol was the best.Sodium hydroxide could be extracted by this three extracting agents from sodium aluminate solution,the concentration of sodium hydroxide in the oil could reach 34g·L-1.更多还原
