摘要
本文比较了三氯乙烯和氯仿对糠醛的萃取特性及其物化特性。给出了两者逆流萃取时的操作线方程。用图解法比较萃取塔及蒸馏塔的理论级数。通过比较,发现三氯乙烯的综合性能略优于氯仿。
In this paper, comparisons are made between trichloroethylene and chloroform in respect of properties of the extracting furfural properties and the properties of physics and chemistry. the operating line equations for countercurrent extraction with two solvents are given. Besides, the theoretical stages of extraction and distillation columns of this two solvents are compared by graphic method. It is found that the comprehensive properties of trichloroethylene are slightly better than that of chloroform.
