Détermination directe des constantes cinétiques d'une réaction chimique par microcalorimétrie à conduction application à la saponification des diesters
C. Zahra,R. Romanetti +1 more
TL;DR: In this article, the authors proposed a direct determination of the kinetic constants of competitive consecutive reactions based on thermograms recorded with a Calvet conduction microcalorimeter using a computing program which includes numerical integration of differential equation systems, signal convolution with an experimental function of apparatus (to get rid of the inertness of the detector-recorder system) and the optimization of the adopted model parameters.
