本工作研究了二环已基-18-冠-6(DC18C6)和二环已基-15-冠-5(DC15C5)在1,2-二氯乙烷中对苦味酸的萃取,提出了萃合物在有机相中离解的萃取模型,求得了萃合常数和有机相中萃合物的离解常数。
In this work, the extraction of picric acid from dicyclohexyl-18-crown-6 (DC18C6) and dicyclohexyl-15-crown-5 (DC15C5) in 1,2-dichloroethane was studied. The dissociation model of the compound in the organic phase was used to determine the extraction constant and the dissociation constant of the complex in the organic phase.
