摘要
本文测定了沸点仪的持液量,其值为1.56 cm^3,应用沸点仪测定了甲醇-乙醇二元系的相平衡数据,与文献数据一致,证明了此测定方法的可靠性。应用沸点仪测得了巴豆醛-三聚乙醛二元系常压下的相平衡数据,同时测取了巴豆醛和三聚乙醛的蒸汽压数据,并用安妥因方程进行了关联。
The liquid holdup of ebulliometer used in this research was determined to be 1.56 ml. The vapor-liquid equilibrium data of methanol-ethanol system are measured by the ebulliometer to confirm the reliability of the apparatus used. The vapor-liquid equilibrium data of trans-2-butenal-paraldehyde at 110.3kPa was obtained by ebulliometric measurement. The data of the saturated vapor pressure-temperature dependence of trans-2-butenal and paraldeyhyde were measured and correlated by Antoine equation.
