固-液接触法制备乙烯

Preparation of Ethylene by Solid-Liquid Contact Method

采用滴液式气体发生器为反应装置,以固体乙烯利和30%氢氧化钾溶液制备乙烯。利用固-液接触法制备乙烯,反应速率可控,无盐析和液泛现象,制气效率达90%以上,并且实验装置体积小、制气量大,为实验室制备乙烯提供了一种简便安全的方法。

In this paper,using a drip-type gas generator as the reaction apparatus,ethylene was prepared by solid ethylene and 30%potassium hydroxide solution as raw materials.The solid-liquid contact method to prepare ethylene had the advantages of controllable reaction speed,no salting out and liquid flooding phenomenon,gas production efficiency of more than 90%,and the small volume of experimental equipment and large gas production.It provided a convenient and safe method for laboratory-scale ethylene production.
