<正> 由于我院化工系化工厂生产上的需要,希望将含有少量乙醇的粗氯仿设法洗净,从而得到工业氯仿,再行提供生产使用:为此,我们须先求得这一三元体系的液相平衡关系,然后进一步利用低沸点恒沸物的特性来提净。考虑到工业上液体物料的计量上,体积量度较重量量度更为方便,实验中采用了体积百分数关系并绘制了相图;参考了恒沸物重量组成也寻求出其体积百分组成,最后提出利用所得相图,如何萃取洗净从而获得工业氯仿的措施。

Due to the production needs of the chemical plant of the chemical engineering department of our hospital, we hope to try to wash the crude chloroform containing a small amount of ethanol, so as to obtain industrial chloroform, and then provide production use: To this end, we must first obtain the liquid phase equilibrium relationship of this ternary system, and then further use the characteristics of low boiling point azeotrope to purify.Considering that the volume measurement is more convenient than the weight measurement in the industrial liquid material measurement, the volume percentage relationship is adopted in the experiment and the phase diagram is drawn.By referring to the weight composition of azeotrope, the volume percentage composition of azeotrope is also sought. Finally, the measure of how to extract and wash to obtain industrial chloroform is proposed by using the obtained phase diagram.
