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: 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.
