Abstract: Cyanoethyl derivatives and sulfoxides have good solvent properties for aromatics. Ternary systems of different groupings have been investigated. These include thio-dipropionitrile and oxy-dipropionitrile; alkanes, cyclanes, olefines, cycloolefines; and monocyclic and bicyclic aromatics. Ternary system with dimethyl sulfoxide was also studied. In liquid-liquid extraction, compromise has always to be made between selectivity and solubility. A method for the choice of solvents was presented. The results indicate that the order of adaptability is dimethyl sulfoxide> oxy-dipropionitrile> thio-propionitrile.
摘要: 腈乙基化合物和亚砜化合物均对芳烃有较好的溶解性能。考查了氧二丙腈与硫二丙腈和烷、环烷、烯、环烯与单环芳烃、双环芳烃等不同三元体系的萃取平衡。也考查二甲亚砜的一些溶剂性能。 在液液萃取中,溶剂对某组份的选择性与其溶解度常有矛盾。提出了一个综合判断溶剂效能的方法。从处理数据结果可以看出二甲亚砜有很好的效能,氧二丙腈次之,硫二丙腈较差。
