Abstract: An isobaric vapor-liquid equilibrium apparatus for elevated pressures was designed and made by the authors. The isobaric vapor-liquid eqilibrium data of three binary systems(isobutene-isoprene,isobutene-chloromethane and isoprene-chloiomethane) and a tertiary system (isobutene-isoprene-chloro-methane at l0.3bar were determined with this apparatus. Experimental data obtained correlated satisfactorily with Martin-Hou Equation of State(81).

摘要： 本文用自制的等压法加压汽液平衡装置测定了在10.3bar压力下异丁烯_(1)-异戊二烯_(2)、异丁烯_(1)-氯甲烷_(3)、异戊二烯_(2)-氯甲烷_(3)三个二元体系及异丁烯_(1)-异戊二烯_(2)-氯甲烷_(3)三元体系的汽液平衡数据.并用马丁-侯状态方程式进行了关联,得到了良好的结果.
