采用绝热量热法测量了由离子液体1-乙基-3-甲基咪唑磷酸二甲酯[Emim][DMP]分别与CH_3OH+H_2O和C_2H_5OH+H_2O构成的两组三元工质溶液体系[Emim][DMP](1)+CH_3OH(2)/C_2H5OH(2)+H_2O(3)在常压、温度范围为298.01~323.34 K、不同浓度下的比热容。采用多项式函数对实验数据进行拟合,获得模型方程中的拟合参数。比热容的计算值与实验值的平均相对偏差分别为0.49%和0.80%。
Two sets of ternary working solution system consisting of 1-ethyl-3-methylimidazolium dimethyl [Emim] [DMP] and CH_3OH + H_2O and C_2H_5OH + H_2O were measured by adiabatic calorimetry [ Emim] [DMP] (1) + CH_3OH (2) / C_2H5OH (2) + H_2O (3) The specific heat capacities at different concentrations at atmospheric pressure and temperature range from 298.01 to 323.34 K. The polynomial function was used to fit the experimental data and the fitting parameters in the model equation were obtained. The average relative deviations between calculated and experimental values of specific heat capacity were 0.49% and 0.80%, respectively.
