摘要(Abstract)：

松节油的主要成分α-蒎烯、β-蒎烯和对伞花烃都是合成香料、医药以及化妆品的重要原料,为了从松节油中分离提纯这些物质,需要测定该体系的汽液平衡数据。利用改进的Dvorak-Boublik汽液双循环平衡釜测定了α-蒎烯+对伞花烃和β-蒎烯+对伞花烃两个二元体系分别在53.3kPa和80.0kPa下的汽液平衡数据,用VanNess提出的点检验法对实验数据进行了热力学一致性检验,结果符合热力学一致性要求。用Wilson、NRTL、UNIQUAC模型对各体系的汽液平衡数据进行关联,并得到相应的模型参数、汽相组成偏差和泡点温度偏差,结果表明计算值与实验值的偏差较小,汽相组成和泡点温度的平均绝对偏差最大值分别为0.0054和0.19℃。实验所测数据及关联结果能够为该体系的精馏设计提供基础数据。
