Vapor−Liquid Equilibria in the 2-Methylcyclohexanol + 2-Methylcyclohexyl Ethanoate System at 101.325 kPa

Abstract

Vapor-liquid equilibrium data were measured using the S Ä wie ¸tosławski ebulliometric still in the binary 2-methylcyclohexanol + 2-methylcyclohexyl ethanoate system at a constant pressure of (101.325 ( 0.070) kPa. The saturated vapor pressures were also measured for samples of mole fraction purity of 99.97 % 2-methylcyclohexanol and 99.98 % 2-methylcyclohexyl ethanoate over wide temperature ranges by comparative ebulliometry. The experimental data were correlated using the maximum-likelihood method, and overall measures of data reproducibility are given. The results are compared with literature data. VLE experimental data were tested for thermodynamic consistency by means of several different consistency tests and were demonstrated to be consistent.
