Cyclohexanol is an important intermediate in production of adipic acid and a-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, the process low selectivity or explosion risks in oxidation unit. In order 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 temperature range from 298.2 to 338.2 K. The experiments were conducted in a temperaturecontrolled glass cell and the received data were correlated with NRTL and UNIQUAC 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. 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.
