本文结合生产的情况,研究了P-350和TBP对环烷酸萃取(钅兰)钕铁钙铜性能的影响。作为添加剂P-350或TBP都可以代替C_7—C_9混合醇。在实验条件下,环烷酸—P350和环烷酸—TBP萃取体系的正协萃或负协萃效应都不太显著。并对所观察协萃现象的原因和在分离上的应用进行了讨论。
In this paper, the effects of P-350 and TBP on the performance of naphthenic acid extraction (钅 兰) neodymium iron-calcium-copper were studied. As an additive P-350 or TBP can replace C_7-C_9 mixed alcohol. Under the experimental conditions, the positive synergistic effect or negative synergistic effect of naphthenic acid-P350 and naphthenic acid-TBP extraction system are not significant. The reasons for the observed synergies and their application in separation are also discussed.
