【摘要】 研究大学物理化学实验中产生的萘-环己烷废液中环己烷的回收。对先简单蒸馏再精馏得到环己烷和直接精馏得到环己烷两种方法进行了比较。发现使用第二种方法回收时间短,效率高,且得到的环己烷纯度能满足实验要求。更多还原

【Abstract】 Researching the recovery methods of cyclohexane in the mixture of naphthalene-cyclohexane in physical chemistry experiment.A comparison between getting cyclohexane by simply distillation then rectification and getting cyclohexane by direct rectification showed that the later had shorter recovery time,higher efficiency,and the purity of cyclohexane was satisfied with the requirements of experiments.更多还原
