摘要
相图是对物质进行分离提纯的基础．本文采用差热分析法，测定了来甲酸-苯混合物的DTA曲线，从中获得其组成和峰温的关系，并由此绘制出苯甲酸-苯二元凝聚系统的相图．实验结果表明，差热分析法比步冷曲线法更适合于对多元凝聚系统复杂相图进行研究．
A phase diagram is the base of isolating and cleansing substances. Thephase diagram of the two-component condensed system of benzoic acid-naphthalene ismapped by the composition and the peak temperature from the DTA curve of the benzoicacid-naphthalene. The DTA is more suitable for the studies of complex phase diagrams ofthe multicomponent condensed system than the cooling curve method.
