摘要
研究了伯胺 Ｎ１９２３ Ｃ Ｃｌ４ 溶液对乳酸的萃取平衡。结果表明，萃合物的组成为 Ｎ１９２３·２／３ Ｈ Ａ，萃取平衡常数 Ｋｅｘ，２／３为 ２６３。还探讨了稀释剂。
The extraction of lactic acid(HA) from its aqueous solution with primary amine N1923(B) in carbon tetrachloride was studied at 298K.The results show that the extraction equilibrium can be expressed as B (0) +2/3HA=B·2/3HA (0) .The influence of diluents,temperature and salting out agents on the extration equilibrium was also discussed.
