实验室制备乙炔的一种新方法

The Improvement in Producing Acetylene

改进了以水或饱和食盐水与碳化钙反应制备乙炔的方法 ,使产量增加 2 0 % ～ 48% ,并且使反应变的平稳 。

The way discussed in this article helps us to improve the method in producing acetylene through the reaction between water or saturated salt water and calcium carbide,increases the quantity of producing gas from 20% to 48% and makes the reaction calm,easy to operate and observe.
