Thermodynamic Studies on the Phase Equilibria of Ternary {choline chloride + Glucose + water} Systems at 298.15 K

Saccharides as the most abundant class of biomolecules are currently the subject of many researchers due to their hydroxy rich property, coordinating ability and other characteristics. In recent years, thermodynamic studies of saccharides in the presence of electrolytes and in aqueous solution are significantly important in different areas including biology, biochemistry, catalysis and pharmaceutical industry [1, 2]. Choline chloride is an organic compound and a quaternary ammonium salt. It is an important additive in feed which accelerates growth. It forms a deep eutectic solvent with urea, ethylene glycol, saccharides and many other compounds [3]. In this work, vapor-liquid equilibria of ternary {Choline chloride + Glucose + water} system has been studied which can be used to describe intermolecular interactions in the electrolyte solutions [4]. Water activity and vapor pressure for this systems have been determined by the isopiestic method.
