Description

technical field [0001] The invention relates to a device for accurately measuring the heat of dissolution of energetic materials and a testing method, belonging to the field of physical and chemical testing. Background technique [0002] The heat of solution refers to the heat emitted or absorbed when one mole of solute is dissolved in a large volume of solvent at a certain temperature and pressure (usually the standard condition of temperature is 298K and pressure is 101kPa). As a special chemical substance, energetic materials are often the key objects of research for their detonation velocity, energy, and density. However, with the development of industrialization of energetic materials, their heat of solution has become an important physical parameter, because It is related to the production rate control and safety research in the synthesis of energetic materials and process modification. [0003] At present, Calvin calorimetry is widely used to measure the heat of solu...
