KINETIC AND THERMAL STABILITY STUDIES OF BISPHENOL-C DERIVATIVES

Bhavin Dhaduk, Sonali Borkar.

Abstract
Thermal study of some novel bisphenol-C derivatives has been investigated using TG and DSC techniques under nitrogen atmosphere at the heating rate of 10 ºC min-1. The nature and position of the substituents affect DSC transition, thermal stability, and kinetic parameters. Melting transitions (57-237 oC) and heat of fusion (15-78 kJ mol-1) of the compounds have been determined from DSC curves. Bisphenol-C derivatives are thermally stable up to about 215-350 oC and followed either integral or fractional order degradation kinetics due to structural dissimilarity—different magnitudes of n, Ea and A suggested different degradation mechanisms. Large and negative magnitudes of ∆S*confirmed a highly ordered transition state, while large and positive magnitudes of ∆S* confirmed a less ordered transition state.

Key words: Kinetic parameters; Bisphenol-C; Thermal decomposition; TG; DSC.
