Abstract The physicochemical properties of the mixed solvent of 2‐piper‐idineethanol (2‐PE), sulfolane (TMS) and water were determined over a wide range of temperatures and compositions. The density, the viscosity and the dissociation constant, as well as the solubility of N 2 O in this mixed solvent were correlated as a function of temperature and composition over the entire experimental range. The models are useful not only for the ternary solvent system, but also for the binary solvent systems, such as 2‐PE+H 2 O and TMS+H 2 O. From the regression, it has been found that the interaction of aqueous 2‐PE solution and aqueous TMS solution is negligible.
