摘　　要：本文测定了乙酸、丙酸及其混合物在70～110℃和4～67 kPa范围内的气相PVTx数据,并用二缔模型处理,得到了乙酸、丙酸及其混合物的二缔平衡常数和缔合焓的实验值。这些缔合常数可用于汽液平衡计算。Vapor phase PVTx properties of acetic acid, propionic acid and their mixtures were measured over the range of 70 to 110℃ and 30 to 500 mmHg. The data were correlated with an association model proposed previously. The thermodynamic dimerization constants and heats of association obtained can be used for VLE calculation.
