Vapor Pressure Measurement and Correlation of Acetone Oxime Methyl Ether
摘要
Abstract
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.关键词
