摘要
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.
Using the solution reaction isoperibol calorimeter, the molar solution enthalpies of room temperature ionic liquid, 1-ethyl-3-methylimidazolium ethyl sulfate (EMIES), with various molalities were determined at T = 303.150 K in water. According to Pitzer' s electrolyte solution theory, the molar solution enthalpy of EMIES at infinite dilution, Delta(s)H(m)(0), and Pitzer's parameters: beta(MX)((0)L), beta(MX)((1)L) and C-MX(phiL) were obtained. Then the values of apparent relative molar enthalpy L-phi, and relative partial molar enthalpy of solvent and solute (EMIES), (L) over bar (1) and (L) over bar (2) were calculated, respectively.
