ABSTRACT:
A stable isothermal calorimeter wherein the material under study is contained in a thermally conductive reactor vessel which is surrounded by a heat transfer fluid. The material is maintained at the boiling point of the heat transfer fluid which is in turn cntrolled by controlling the pressure of the fluid's vapor space. The heat transfer fluid is vaporized by the heat released by exothermal reaction of the material under study and the vaporized fluid condensed in a condenser. The rate of liquid accumulation in the condenser is proportional to the energy release rate of the material.
