TLDR
In this article, the possibilities of using direct calorimetric measurements for the determination of kinetic parameters of processes are discussed in terms of the choice of an appropriate method of reproduction of the course of changes in the heat power generated in time.Abstract:
The possibilities of using direct calorimetric measurements for the determination of kinetic parameters of processes are discussed in terms of the choice of an appropriate method of reproduction of the course of changes in the heat power generated in time, i.e. thermokinetics. Such methods are presented and it is concluded that many of these methods permit reproduction of the thermokinetics in the same way as if the experimental thermal curve were obtained in a calorimetric system characterized by a time constant 100–200 times as large as that for the thermal inertia of this calorimetric system.read more

Suggested practice for classification of calorimeters
TL;DR: It was found useful, for the sake of simplicity and sharpness of definition, to base the operational classification on a criterion of temperature control which leads to a clear-cut distinction between “adiabatic”, “ordinary” and “true or extended isothermal” calorimeters.
