Abstract

Procédé de mesure de la vitesse d'échauffement spontané d'une réaction et calorimètre adiabatique correspondant Ce procédé consiste à disposer un échantillon à analyser à l'intérieur d'un récipient place dans une chambre de réaction; à chauffer la chambre de réaction, l'environnement et le récipient à une température permettant l'initiation de la réaction exothermique et à laisser la réaction se poursuivre jusqu'à la fin d'une façon adiabatique. Permet de déterminer à partir de mesures de température le potentiel d'explosion de produits chimiques réactifs.Method for measuring the rate of spontaneous heating of a reaction and corresponding adiabatic calorimeter This method consists in placing a sample to be analyzed inside a container placed in a reaction chamber; heating the reaction chamber, the environment and the vessel to a temperature allowing the initiation of the exothermic reaction and allowing the reaction to proceed to completion in an adiabatic fashion. Used to determine from temperature measurements the explosion potential of reactive chemicals.
