采用动态法,利用Rose釜测定了丙酮肟甲醚在307.75~344.05 K的饱和蒸气压,并应用Antoine方程进行关联,获得Antoine常数A、B、C分别为20.64,2338.72和?88.86,Antoine方程计算值与饱和蒸气压实验测定值之间的平均相对误差为0.45%.在此基础上,通过Clausius-Clapeyron方程计算得到丙酮肟甲醚在307.75~344.05 K温度范围内的平均摩尔蒸发热为36479.24 kJ?kmol?1.所得饱和蒸气压方程对丙酮肟甲醚精馏分离过程的设计与操作具有重要意义.

Saturated vapor pressures of acetone oxime methyl ether(AOME) were measured in the temperature range of 307.75~344.05 K by dynamic method in a Rose still. The measured saturated vapor pressures and temperatures were correlated by Antoine equation and the constants of equation were determinated as A=20.64, B = 2338.72, and C = ?88.86 by nonlinear regression method. The averaged relative error between saturated vapor pressures calculated from the Antoine equation and the experimental data is 0.45%. Based on the experimental data of vapor pressures, the latent heat of vaporization of acetone oxime methyl ether was also obtained by Clausius-Clapeyron equation and its value is 36479.24 kJ?kmol?1 in the temperature range of 307.75~344.05 K. It is very important to provide the Antoine constants and latent heat of acetone oxime methyl ether for the design and operation of its distillation separation process.
