The decomposition reaction of pentaerythritol tetranitrate (PETN), C(CH 2 ONO 2 ) 4 , under static high pressure was examined by conducting observations and infrared measurements up to 5 GPa at around 500 K. The thermal decomposition of PETN proceeded rapidly at around 500 K and formed a fluid consisting of N 2 O, CO 2 , and H 2 O. The rate of the decomposition reaction at 423 K increased as the pressure increased, indicating a negative activation volume. The initial step of the decomposition reaction of PETN under static pressure was presumed to be the elimination of HNO 3 .
