Liquid-liquid equilibrium of alcohol–ester systems with deep eutectic solvent on the base of choline chloride

The liquid-liquid equilibrium (LLE) for the mixtures of ethanol – ethyl propionate, n-propanol – n-propyl propionate and n-butanol – n-butyl propionate with deep eutectic solvents (DES) was studied. DES was used on the basis of choline chloride with malonic acid in a mole ratioof 1:1. The studies were carried out at two temperatures, 293.15 K and 313.15 K and atmospheric pressure. The compositions of the coexisting organic and DES phases were...
