【摘要】 应用改进型汽液双循环平衡釜测定了 (?)atm 下六甲基二硅醚-甲苯二元体系汽液平衡数据。该体系无恒沸点,但在六甲基二硅醚液相摩尔浓度高于0.85的区域,其平衡汽液相摩尔组成接近相等。使用Wilson 活度系数方程对汽液平衡试验数据进行了关联,计算值与试验值符合较好。更多还原

【Abstract】 The experimental data of vapor-liquid equilibrium for hexamethyldisiloxane-toluene are determined using modified vapor-liquid bi-circulating equilibriumstill at 1 atm.The composition of vapor is almost the same as that of the liquidin the region of higher concentrations of hexamethyldisiloxane.Experimentaldata are correlated using Wilson’s equation.The calculated values are consistentwith the experimental ones.更多还原
