摘要
采用非分析法,在拟静态条件下,用新型泵式沸点仪测定了常压下醋酸-醋酸乙烯(酯)-巴豆醛三元系在不同液相组成时的沸点,选用Wilson方程对所测数据进行关联,建立了该三元系的汽液相平衡热力学模型,并推算了达到汽液平衡时的汽相组成和泡点温度.将泡点计算值与沸点实验值相比较,最大绝对偏差为1.31K,结果比较满意.
In the quasi-static condition, not analyzing the composition of the liquid phase ,the boiling points of the acetic acid-vinyl acetate- crotonic aldehyde system were determined at the atmospheric pressure with a new type of pump-ebulliometer. These data had been correlated with Wilson equation. The (thermodynamic) model of the system was proposed, by which the equilibrium composition of the vapor phase and the (bubble) point temperature had also been predicted .The max absolute deviation of the calculated bubble points was (1.31 K) from the experimental data, which showed that good agreements were obtained.
