摘要
依据精馏原理设计并建立了一套加压共沸点测定装置。经检验,该装置的操作稳定性好,测量精度高。用该装置测定了苯-乙醇、正庚烷-乙醇两组二元体系在101.3、302.6、506.9、709.3和911.9kPa下的共沸数据,实验值与文献值符合良好。
A new stainless steel apparatus to measure multicomponent azeotropes under superatomopheric pressure was developed and a series of experimental data were obtained. Results show that this apparatus can measure azeotropic data stably, quickly and accurately. Binary azeotropes of benzene-ethanol, n-heptane-ethanol system under pressure of 101.3, 302.5, 506.0, 709.3, 911.9kPa were measured. The experimental data were in good agreement with those reported by literature.
