摘要/Abstract

摘要： 采用等温溶解平衡法测定N,N′-二(2-羟丙基)哌嗪(HPP)?Na2SO4?H2O三元体系在273.15和298.15 K下的相平衡数据，采用湿渣法测定其平衡固相数据，绘制等温相图。用改进的单组分电解质Pitzer方程计算该体系中Na2SO4和Na2SO4?10H2O的溶解平衡常数，并对相平衡数据进行理论计算。结果表明，273.15 K时存在3个结晶区，298.15 K时存在4个结晶区。HPP的存在降低了Na2SO4和Na2SO4?10H2O的相转变温度，使298.15 K下的相图中存在Na2SO4的结晶区域，且273.15和298.15 K的相图中不存在纯HPP的结晶区域。理论计算与实验数据的均方根偏差不高于0.0290，表明相平衡数据计算值与实验值较吻合，证实了改进的单组分电解质Pitzer方程适用于该体系计算。
