在303.150K下,利用等温溶解反应量热计测定了不同浓度硫酸乙酯1甲基3乙基咪唑(EMIES)室温离子液体在水中的摩尔溶解热(ΔsHm),根据Pitzer理论得到了EMIES的无限稀释摩尔溶解热(ΔsH0m)和Pitzer焓参数β(0)LMX,β(1)LMX和CФLMX,并计算了表观相对摩尔焓和溶质、溶剂的相对偏摩尔焓.
At 303.150K, the molar heat of solution (ΔsHm) of room temperature ionic liquids with different concentrations of methyl ethyl 3-ethylimidazole (EMIES) in water was determined by isothermal solution reaction calorimeter. According to Pitzer theory, The molar enthalpy of solvation (ΔsH0m) and Pitzer enthalpy parameter β (0) LMX, β (1) LMX and CФLMX were diluted and the apparent relative molar enthalpies and the relative partial molar enthalpies of solute and solvent were calculated.
