This work shews that the modified UNIFAC model can be applied to organic chlorides for predicting mixing enthalpies and activity coefficients, but the group-interaction parameters must be estimated from h~E_(exp). On the basis of h~E_(exp), twelve pairs of new group-interaction parameters: CH_2/CCl, CH_2/CCl_3, CH_2/CCl_4, ACH/CCl, ACH/CCl_2, ACH/CCl_3, ACH/CCl_4, CCl_2/CCl_4, ACCl/CH_2, ACCl/ACH, ACCl/ACCH_2 and ACH/ ACNO_2 have been estimated. The results can be used to predlict simultaneously mixing...

This work shews that the modified UNIFAC model can be applied to organic chlorides for predicting mixing enthalpies and activity coefficients, but the group-interaction parameters must be estimated from h~E_(exp). On the basis of h~E_(exp), twelve pairs of new group-interaction parameters: CH_2/CCl, CH_2/CCl_3, CH_2/CCl_4, ACH/CCl, ACH/CCl_2, ACH/CCl_3, ACH/CCl_4, CCl_2/CCl_4, ACCl/CH_2, ACCl/ACH, ACCl/ACCH_2 and ACH/ ACNO_2 have been estimated. The results can be used to predlict simultaneously mixing euthalpies and activity coefficients.

编制了UNIFAC修正模型的参数估算和h~E、γ_i的推算程序。在二元体系的实验数据基础上估算了参数,并据此对h~E和γ_i作相互推算,证明此修正模型可推广应用于有机氯化物,但模型参数须根据h~E_(exp)求得。本工作据h~E_(exp)估算出12对新的基团相互作用参数,它们兼有推算h~E和γ_i的功能。
