Thermal stability and specific heat estimation of pyridinium cation-based surfactant ionic liquids using TGA-DSC

Abstract

In recent years, the ultimate goal is to learn how to select ionic liquids specifically for materialistic or molecular level applications of these neoteric materials. Progress has been initiated, but much more is to be needed in order to optimize the full potential of ionic liquids in every aspect of modern day science. A number of engineering parameters need to be determined for the challenging flourishing of ionic liquids in sustainable commercial applications. In particular, the general absence of specific heat capacity (Cp) data is a substantial obstacle for the design of chemical reactors and heat transfer systems, if any ionic liquid based processes are to be developed beyond the laboratory scale. The specific heat capacities of ionic liquids and their mixtures are having significant importance in chemical engineering work accompanying with the design and operation of reactors and heat related operations, required for commercialization of ionic liquids and technologies associated with the ionic liquids. In this work, thermal profiles of the surfactant or sponge ionic liquids have been explored very aptly for the measurements of specific heat capacity (Cp) of the pyridinium cation-based surfactant or sponge ionic liquids.
