Splitting of the liquid solution and the compositions of liquid phases in the water-n-propanol-n-propyl acetate system at 293.15, 303.15, and 313.15 K

New experimental data on solubility and liquid-liquid phase equilibrium in a water-n-propanol-n-propyl acetate system under polythermal conditions are presented. The results of modeling the liquid-liquid equilibrium using the UNIFAC model are given.

Experimental study of chemical equilibrium and vapor-liquid equilibrium calculation for chemical-equilibrium states of the n-propanol-acetic acid-n-propyl acetate-water system

Chemical equilibrium data for the n-propanol-acetic acid-n-propyl acetate-water system at 303.15 K are presented. The results of UNIFAC-based modeling of the vapor-liquid equilibrium in the system at 303.15 and 313.15 K are reported.

Kinetics of esterification and hydrolysis in the n-propanol + acetic acid + n-propyl acetate + water system in homogeneous and heterogeneous composition areas

The reaction kinetics of esterification-hydrolysis in the n-propanol + acetic acid + n-propyl acetate + water system is considered. The phase state of the reaction mixture-homogeneous or two-phase-can change in the course of reaction due to the occurrence of a splitting region. For the analysis of the behavior of the system under these conditions, experimental data on the reaction kinetics were obtained at 293.15 K for both the homogeneous and heterogeneous regions of compositions. The evolution of the reaction system in time with the simultaneous occurrence of a chemical process and interphase mass transfer is also considered.
