Abstract: The vapor liquid equilibrium data for cyclohexane -1 -butanol, cyclohexane -toluene and 1-butanol-toluene binary systems were determined under pressures from 101. 3 to 911. 9 kPa with the dual circulating VLE apparatus. The data under five pressures were combined and correlated by the Wilson equation, and the relationship of the Wilsons energy parameters with pressures were determined for each system. Good results were obtained. The experimental data indicated that minimum boiling azeotropes were formed for cyclohexane- 1 - butanol and 1 - butanol-toluene binary systems under the studied pressures.

摘要: 以环已烷、正丁醇、甲苯为代表,进一步研究了烷烃、芳烃和低级醇在加压下的相平衡规律。测定了有关3个二元体系在101.3、304.0、506.6、709.3、911.9kPa下汽液平衡数据,对实测数据进行了统一关联,计算结果与实测值符合良好。环己烷-正丁醇、正丁醇-甲苯体系在所测压力下均形成最低共沸点。
