We report the results of our studies on optical and thermal properties of ternary mixture of compounds, viz., laurylpyridinium chloride (LPC), cholesteryl nonanoate (CN) and orthophosphoric acid (H3PO4). These mixture exhibits a very interesting cholesteric and induced reentrant smectic-A phases for different concentrations of CN sequentially when the specimen is cooled from its isotropic phase. The temperature variations of optical-density and ultrasonic measurements have been discussed. Thermodynamical response of birefringence has also been discussed to understand: the phase stability, chemical structure and molecular dynamics of the multi-component system of liquid crystalline materials.
