摘要
使用ＤＭＡ５５型精密密度计和ＤＭＡ５１２型高压外测量池，测定了环己烷－乙酸乙酯体系在温度２８８．１５—３１８．１５Ｋ，压力从常压—１９．５ＭＰａ下的液体密度。应用三重随机局部组成密度模型，预测了该体系在不同温度、压力下的密度。
The liquid densities of the system of cyclohexane ethyl acetate have been measured as a function of composition in the temperature range of 288 15K to 318 15K and pressures from ambient to 19 51MPa using an Anton Paar DMA55 density meter with a DMA512 external measuring cell for high pressures The triplet random local composition model of mixture density was used to predict the densities at various temperatures and pressures The results were in good agreement with the experimental data
