Synthesis, characterization and thermal decomposition of 2’-amino-6’-(1H-indol-3-yl)-1-methyl-2-oxospiro-[indoline-3,4’-pyran]-3’,5’-dicarbonitrile under non-isothermal condition in nitrogen atmosphere Nalini, Ganesan Jayachandramani, Natesan Suresh, Radhakrishnan Thanikachalam, Venugopal Manikandan, Govindasamy Spirooxindole Coats-Redfern method Thermal decomposition Flynn-Wall-Ozawa method Thermodynamic parameters Kissinger-Akahira-Sunose method The kinetics and decomposition of a new spirooxindole compound, 2’-amino-6’-(1H-indol-3-yl)-1-methyl-2-oxospiro[indoline-3,4’-pyran]-3’,5’-dicarbonitrile was studied by thermo gravimetric technique under non-isothermal conditions. The kinetic parameters were calculated using model-free (Friedman, Kissinger-Akahira-Sunose and Flynn-Wall-Ozawa methods) and model-fitting (Coats-Redfern) methods. The results of the Friedman isoconversional analysis of the thermo gravimetric data suggested that the investigated decomposition process follows a single-step.
