【摘要】 以水为萃取剂，萃取分离乙醇和环己烷，得到乙醇水溶液和粗环乙烷。粗环乙烷经精馏提纯，得到纯度为99．91％的纯品；乙醇水溶液经分馆、CaO脱水后得无水乙醇，纯度达99．74％。更多还原

【Abstract】 The paper shows the recovery method of the waste liquid of ethanol - cyclohexanc produced during the exenment of college physied chemisty .The water as extractor, ethanol apuous solution and cyclohexane wele obtained by meams of extraction Through the rectification and extraction can obtain the purified cyclohexane(punty is 99. 91 % ). Absolute alcohol(purity is 99. 74%) was obtained from the ethanol aquous solution ty means of rectification and CaO.更多还原
