【Abstract】 A new adiabatic caolorimeter (accelerating rate calorimeter) is introduced. The instrument is used for hazardous exothermal reaction experiments. It records changes of temperature and pressure in reaction process, then the onset reaction temperature, the arrival time of maximum reaction rate and the kinetic information of reacting substances are analyzed by software. The conclusions can be extended to large scale reaction of production process. The application of the instrument in measuring safety properties of substances is exemplified with DTBP experiment.更多还原
