为拓展低共熔溶剂的潜在应用范围,探索其作为吸收式制冷工质对中吸收剂的可行性,测定制冷剂二甲醚在氯化胆碱和乙二醇组成的低共熔溶剂中的溶解度.在制备氯化胆碱和乙二醇摩尔比分别为1∶3和1∶4的2种低共熔溶剂Ethaline(1∶3)和Ethaline(1∶4)的基础上,采用等体积饱和法分别测量温度在283.15-343.15 K内的二甲醚在Ethaline(1∶3)和Ethaline(1∶4)中的溶解度,使用非随机双液模型对测量得到的实验数据进行关联.结果 表明:对二甲醚/Ethaline(1∶3)和二甲醚/Ethaline(1∶4)而言,模型计算值与实验数据的平均相对偏差分别为2.39%和3.34%,可为所研究混合物的进一步工程应用提供基础的相平衡数据.
Solubility of DME in choline chloride/ethylene glycol deep eutectic solvent
In order to extend the potential application of deep eutectic solvent,and explore the possibility of the deep eutectic solvent as the absorbent used in the absorption refrigeration cycle,the solubility of the refrigerant dimethyl ether in the choline chloride/ethylene glycol deep eutectic solvent was investigated.The choline chloride/ethylene glycol deep eutectic solvent were prepared at the molar ratio of 1∶3 and 1∶4 and were named as Ethaline(1∶3)and Ethaline(1∶4),respectively.Then,the solubility of dimethyl ether in Ethaline(1∶3)and in Ethaline(1∶4)was measured based on the isochoric saturation method in the temperature range from 283.15 to 343.15 K,and the experimental data were correlated using the non-random two-liquid model.The results show that the average relative deviation between the values calculated from the model and the experimental data is 2.39%and 3.34%for the dimethyl ether/Ethaline(1∶3)and dimethyl ether/Ethaline(1∶4),respectively,and can provide the fundamental phase equilibrium data for the engineering application of the studied mixtures.
