| Abstract: | The paper shows the recovery method of the waste liquid of ethanol - cyclohexane produced during the experiment of college physical chemistry of binary liquid - phase figure. The water used as extractor, ethanol aqueous solution and cyclohexane were obtained by means of extraction. Through the rectification and extraction the purified cyclohexane can be obtain (purity is 99. 91 % ). Absolute alcohol (purity is 99. 74% ) was obtained from the ethanol aquous solution by means of rectification and dehydration of CaO. The purified cyclohexane and absolute ethanol can be suitable to the experiment of binary liquid phase. |
