PREPARATION METHOD FOR HEAT-RESISTANT ENERGETIC MATERIAL PTO

Abstract: a preparation method for a heat-resistant energetic material pto is provided, where pto is synthesized by a one-step reaction with commercial 1h-pyrazolo[3,4-d]pyrimidin-4-amine as raw material under the reaction of fuming hnoand concentrated hso, and the yield is up to 75%. the preparation method is 3 steps shorter than the existing technical route, the reaction time is greatly reduced, the reaction conditions are relatively mild, the process is simpler, and it is easy to scale up in engineering.
