N2 - In this work we report data on solubility of choline chloride and choline acetate in shortchain linear alcohols (ethanol, 1-propanol and 1-butanol) at various temperatures. Furthermore, we synthetized two choline derivatives: hydrogencholine chloride glutarate ([CholGlut][Cl]) and hydrogen choline chloride succinate([CholSucc][Cl]). Their characterization and solubility in short-chain alcohols asa function of temperature are also included. Activity coefficients were calculatedand their comparisons with ideal solutions were discussed. The experimental data were correlated successfully by means of the semi-empirical Grant equation.
