MEASUREMENT OF THE AMOUNT OF HEAT USING A DIATHERMIC COMBUSTION CALORIMETER WITHOUT PREHEATING OF THE CALORIMETER VESSEL IN A THERMOSTAT

Abstract

A new method for measuring the amount of heat on the diathermic combustion calorimeter is presented. The method is based on filling the calorimeter vessel at room temperature and placing of the vessel in the measuring cell of the calorimeter (calorimeter is preliminary brought to a constant temperature) without preheating of the vessel in an isolated thermostat. Placing of a "cold" vessel into the cell and subsequent release of the reactive heat virtually balance each other, thus reducing the load on the temperature controller of the calorimeter. Note that not only pulse, but also the heat release of unrestricted continuance is recorded. Elimination of the preheating thermostat obviously simplifies the device design. The method has been patented.
