摘要
本文用流动汽液平衡釜测定了①戊酮－３－正丙醇③丁酮－戊醇－１两个体系三个温度下的等温汽液平衡数据，三个温度下的数据均通过热力学一致性检验，并用Ｗｉｌｓｏｎ方程和ＵＮＩ－ＱＵＡＣ方程对数据进行了关联，平均汽相偏差小于０．０１，精度令人满意。
Vapor liquid equilibrium data of the following systems were determined atthree different temperatures in a flow still :(1) 3-pentanone-1-propanol(t=41.3, 60.6,80.0℃);(2) methyl ethyl ketone-1-pentanol(t=50.0, 60.0, 70.0℃).The thermody-namic consistency of above systems was checked by area method. Experimental results showthat 3-pentanone-1-propanol system possesses azeotropes. Wilson and UNIQUAC e-qutions were used to correlate the VLE data. The average correlation deviations of vaporcomposition △_(y1) were less than 0. 01.
