•Biocompatible ionic liquids based on choline esters were synthesized in this work.•Solubility of choline and choline esters based ionic salt in alcohols were measured.•Activity coefficients were calculated.•Experimental data were correlated by means of the semi-empirical Grant equation.
In this work, we report data on solubility of choline chloride and choline acetate in short-chain linear alcohols (ethanol, 1-propanol and 1-butanol) at various temperatures. Furthermore, we synthesize two choline derivatives: hydrogen choline chloride glutarate ([CholGlut][Cl]) and hydrogen choline chloride succinate ([CholSucc][Cl]). Their characterization and solubility in short-chain alcohols as a function of temperature are also included. Activity coefficients were calculated and their comparisons with ideal solutions were discussed. The experimental data were correlated successfully by means of the semi-empirical Grant equation.
