Kinetics of the thermal degradation of Betanine

Abstract
The paper discussed thermal degradation of betanine, isolated on Sephadex G‐25 and recrystallized from 0.1% HCl. Model solutions of betanine (pH = 5.0) were heated at 60.0, 65.5, 68.5, 72.5, 75.0, 76.5, 81.0, and 86.0°C. Experimental values obtained were used for calculations of the reaction rate constants as well as half‐life values of betanine. The activation energy of betanine was found as E = 144.8 kJ/mol.
