A study on kinetic properties of brucinium hydrogen (s) malate pentahydrate single crystal by Coats Redfern method

K Gayathri, K Rajesh, P Krishnan, K Anandan… - AIP Conference …, 2020 - pubs.aip.org
Single crystals of brucinium hydrogen (S) malate pentahydrate (BH (S) M) were grown from
ethanol–water (1: 1) mixed solvent by slow evaporation method. Structure and crystallinity of
the grown crystal were confirmed by powder X-ray diffraction analysis. Thermal stability and
decomposition process were studied using TGA and DTA analysis. Kinetic analysis of the
thermogravimetric data was carried out by using Coats Redfern relation. Kinetic Parameters,
such as energy of activation (Ea), enthalpy (ΔH#), entropy (ΔS#) and Gibbs energy (ΔG#) …
