Abstract：T he differential accelerating rate calorimeter developed by OmniCal Company is a true adia‐batic calorimeter without thermal dilution .Compared with other thermal analysis instruments ,such as ac‐celerating rate calorimeter(ARC) ,the data obtained from the test can be applied to the calculation of kinet‐ic parameters of energetic materials without phi‐correction .This paper obtained the curves of temperature and pressure versus time of di‐tert‐butyl hydroperoxide(DTBP) as well as the characteristic parameters of initial self‐heating temperature ,adiabatic temperature rise ,adiabatic pressure rise ,the maximum rate ,tem‐perature to maximum rate ,time to maximum rate etc .T he activation energy and the pre‐exponential of ki‐netic parameters of decomposition reaction for DTBP were also calculated .
