摘要

Abstract

In this study

the quasi-static ebulliometric method was used to measure both of the vapor pressures of methyl N-phenyl carbamate (MPC)

and the isobaric vapor-liquid equilibrium (VLE) data of the aniline and MPC binary system. The measured vapor pressure data of MPC

at different temperature ranging from 369.60 to 389.54 K

fitted well with the Antoine equation. The VLE data for the aniline and MPC system at (2.00

4.00

6.00

7.00 and 8.00) kPa were correlated by both of nonrandom two-liquid (NRTL) and Wilson models. The parameters of the two models were obtained by regressing the experimental data

with the absolute temperature deviations of 0.54 K and 0.53 K

respectively. The relative volatility of the binary system calculated was all far more than 1

which gives the conclusion that the high purity MPC can be separated from aniline and MPC binary system by rectification or distillation technology.
