ANALYSIS OF NONISOTHERMAL KINETIC MEASUREMENTS

A computer algorithm is proposed for the numerical analysis of non-iso thermal kinetic measurements. There are no inherent limitations with r espect to the complexity of the reaction mechanism and the temperature profile. The kinetic differential equations are expanded to take into account temperature variation. Numerical integration is performed, us ing higher order Runge-Kutta or Gear algorithms. The results of the an alysis are the activation parameters of the rate-constants. The revers ible, acid catalyzed esterification of cyanoacetic acid in ethanol ser ved as a test. The activation parameters for esterification and hydrol ysis reactions were determined and confirmed by classical analysis.
