摘要:
在常温、常压下采用错流液液萃取装置,研究了以水为萃取剂,多级错流萃取分离1,1,2-三氯乙烷—DMF体系的工艺条件,综合考察了溶剂比和萃取级数对错流萃取结果的影响,结果表明在溶剂比S:F=1:1的比例下,采用四级萃取可使萃余相中1,1,2-三氯乙烷的含量达到99.5%以上,且DMF的回收率同时达到99.5%以上.
Abstract:
The multilevel cross-flow extraction is used to separate 1,1,2-Trichloroethane-DMF System with water as extraction agent.The experimental results show that the content of 1,1,2-trichloroethane could be refined to 99.5% from raffinate and that the recovery rate of DMF could be refined to 99.5% through four times cross-flow extraction with controlling the solvent ratio as 1:1.
