摘要
本工作设计了一套测定共沸数据的差分沸点仪。考核结果表明,该装置具有良好的测温稳定性和组成可靠性;可测定低沸点或高沸点的共沸数据,不需要组成分析也能确定共沸组成。用该装置测定了16个体系的共沸数据.关联得到了共沸温度与共沸组成、共沸压力的关系式。计算值与实测值吻合良好。
In the present work, an apparatus of differential ebulliometer for the determination of azeotropic data has been established. The tests show that the apparatus has high temperature stability and composition reliability. Data for low or high azeotropic boiling point can be measured and azeotropic composition can be determined while composition are not analyzed. Azeotropic data at different pressure for sixteen binary systems are determined. Correlations between azeotropic pressure and temperature and between azeotropic composition and temperature are obtained. The calculated results agree Well with the experimental data.
