氯化锌与2-甲基-1-丁醇或3-甲基-1-丁醇二元体系溶解度和蒸汽压的测定及关联

Measurement and Correlation of Solubility and Saturated Vapor Pressure for ZnCl_2-2-Methyl-1-Butanol and ZnCl_2-3-Methyl-1-Butanol Systems

用平衡法分别测定了氯化锌在2-甲基-l-丁醇和3-甲基-1-丁醇中的溶解度,用静态法分别测定了在100℃～140℃不同温度下含饱和ZnCl2的2-甲基-1-丁醇和3-甲基-1-丁醇的饱和蒸汽压,进一步运用拟二元法原理分别用Glapeyron方程和Antoine方程关联试验数据。结果表明,计算值能较好地与实验值相吻合(对于旋性戊醇和异戊醇,其平均偏差均在1%以内)。这些数据的测得为今后进一步研究加盐精馏分离两种戊醇提供了基础物性数据。

The solubilities of ZnCl,in 2-methyl-1-butanol and 3-methyl-1-butanol systems were measured with equilibrium method,respectively.Saturated vapor pressures of 2-methyl-1-butanol and 3-methyl-1-butanol containing ZnCl,at different temperatures were determined with static method.Based on the principle of virtual binary systems,the correlation value is satisfactorily consistent with the ex-perimental data(average deviation for isoamyl alcohol and active amyl alcohol is within 1%).This provides essential physical data for further investigation of distillation containing salt.
