绿色化合成环己烯实验的探索

Exploration on the Green Synthesis of Cyclohexene in Chemistry Labs

以环己醇为原料，FeCl3·6H2O催化合成环己烯，探讨了催化剂的用量和反应时间对实验结果的影响。结果表明：此法环己烯收率可达86．1％，纯度为98．6％，催化剂价廉易得，实验过程简单、环保，是一条合成环己烯的典型绿色途径。

Cyclohexene was synthesised from cyclohexanol using ferric chloride as catalyst. The effects of catslyst amount and reaction time was studied. The results show that under the most suitable condition for the reaction, the conversion can reach more than 36.1%, and product purity is 98.6%. It also shows that ferric chloride process has many advantages such as cheap and easily obtained catalyst, operation simple, being disposable and reusable, free from pollution, It is a typical simple new ＂green＂ route to the synthesis of cyclohexene.
