摘要
报道了在20、30、40和50℃下,水-氯化锂和乙酵-氯化锂二元系及氯化锂浓度为0.1、0.2、0.3和0.4mol LiCl/kg溶剂下的水-乙酵-氯化锂三元系液体粘度的测定结果。结合李伯耿等人的拟两元模型和Wei等人的局部组成型液体粘度模型,提出了关联含盐三元系液体粘度的拟两元局部组成模型,经对所测的十六组液体粘度数据进行关联,最大平均偏差4.3%,最小平均偏差1.3%。
The viscosities of binary systems, H_2O-LiCl and C_2H_5OH-LiCl, and ternary system H_2O-C_2H_5OH-LiCl(m_(L Ci) =0.1,0.2,0.3 and 0.4) have been measured at 20℃, 30℃ 40℃ and 50℃ By combining pseudobinary method of Bogeng Li et al, and local composition model of viscosity of nonelectrolyte solution of Wet et al, a pseudobinary local composition model was presented to correlate the viscosities of unsaturated solution containing two solvents and one salt. The new model has been tested with the measured viscosity data for the H_2O-C_2H_5OH-LiCl system. The average relative deviation is 2.7%
