Measurements and Correlation of Liquid-Liquid Equilibria for the Ternary System Cyclohexanol + Water + Cyclohexyl Formate at 298.2-338.2 K

Original language description

Cyclohexanol is an important intermediate in production of adipic acid and ϵ-caprolactam. On the industrial scale, cyclohexanol is produced by several methods that suffer from considerable drawbacks, such as a low conversion of the initial substance, low selectivity of the process, or explosion risks in the oxidation unit. To design a new process of indirect hydration of cyclohexene in the presence of formic acid, it is necessary to know the given system properties. In this paper, the data of liquid-liquid equilibrium (LLE) are presented for the system of cyclohexanol + water + cyclohexyl formate under atmospheric pressure and within a temperature range from 298.2 to 338.2 K. The experiments were conducted in a temperature-controlled glass cell and the received data were correlated with the nonrandom two-liquid (NRTL) and universal quasichemical equations in order to obtain binary interaction parameters describing LLE of the given system. The measured data accuracy was specified by the Bachman and Othmer-Tobias equations. The data fitting accuracy was evaluated by the use of the calculated average absolute deviation and the root-mean-square-error values. The NRTL model obtained in this work was compared to a previous published model. The model obtained in this work significantly improves the prediction of ternary data at elevated temperatures. © 2019 American Chemical Society.
