ABSTRACT :

- Chemical equilibrium for the quaternary system propionic acid
+ ethanol + ethyl propionate + water was experimentally studied at
303.15 and 313.15 K and atmospheric pressure. The chemically equilibrium compositions were determined by gas chromatography and nuclear magnetic resonance analytical methods.
- It is shown that chemical equilibrium is reached both in homogeneous and heterogeneous area of composition of reactive mixture. The liquid – liquid equilibrium data for the surface of chemical equilibrium were obtained. The thermodynamic constants of chemical equilibrium at 303.15 and 313.15 K were determined. © 2017 Elsevier B.V.
