摘　　要：采用静态法，利用Rose釜测定了新铃兰醛在391．85-416．35K范围的饱和蒸汽压，并用Antoine方程InP=A-B（T＋C）进行关联，确定了蒸汽压方程的三个参数A=10．701，B=558．048，C=-296．730。新铃兰醛饱和蒸汽压测定值与上述Antoine方程关联值吻合较好，相对误差均在1％以内。所得饱和蒸汽压方程对新铃兰醛精馏分离设计和操作具有重要意义。Saturated vapor pressures of Lyral were measured in the temperature range of 391.85-416.35 K by static method in a Rose still. The measured Lyral saturated vapor pressures and temperatures were correlated by Antoine equation InP=A-B/（T＋C）, and the constants of the equation were determined as A=10.701, B= 558.048, C=-296.730. The average deviations between the Lyral saturated vapor pressures calculated from the above correlated equation and experimental data are less than 1%, this indicates that the correlated values of Lyral saturated vapor pressures agree well with the measured ones. The obtained parameters are useful for the design and operation of the Lyral rectifying tower.
