✦ Synopsis

The physicochemical properties of the mixed solvent of 2-piperidineethanol (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,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+H20 and TMS+H,O. From the regression, it has been found that the interaction of aqueous 2-PE solution and aqueous TMS solution is negligible.
