摘要
测定了303.2～363.2K温度范围内,对苯二甲酸在N,N-二甲基丙酰胺(DMP)、N,N-二乙基丙酰胺(DEP)和N,N-二乙基乙酰胺(DEA)中的溶解度。随着温度的升高,对苯二甲酸在3种酰胺类溶剂中的溶解度都增大;但是在不同的溶剂中表现出不同的温度敏感性,在该温度范围内N,N-二乙基乙酰胺中溶解度对温度最为敏感。实验数据用Buchowski等提出的λh方程进行了关联,实验值与计算值符合良好。
Experimental solubilities of terephthalic acid （TA） dissolved in N, N-dimethyl propionamide （DMP）, N,N-diethyl propionamide （DEP） and N, N-diethyl acetamide （DEA） were determined in the temperature range of 303.2--363.2 K. The experimental results showed that the solubility of TA increased significantly with an increase in temperature and had different temperature sensitivities in different solvents. The solubility data were correlated by Buchowski equation, and the parameters h and λ were regressed, which gave good agreement with all experimental data.
