Abstract

Thermophysical properties such as density, heat capacity, thermal conductivity, viscosity, melting point, solvation properties, mass transport properties in/of ILs, thermal stability, and vapor pressure are important for the development and design of supported ionic liquid (IL) processes -. This chapter focuses on the three last-mentioned properties. Diffusion of (dissolved) gaseous, or liquid reactants in the IL layer plays an important role if supported ILs are used to immobilize homogeneous catalysts or to coat heterogeneous catalysts, and may have an influence on the effective reaction rate. The chapter proposes a strategy to determine the vapor pressure and the rate constant of thermal decomposition of ILs.
