Derivatives of 3(5),4-dinitropyrazole as potential energetic plasticisers

摘要

The development of a pseudo-one pot synthesis of 3(5),4-dinitropyrazole enabled us to use it as a starting material for energetic plasticisers. Its acidic proton allowed simple deriva-tisation on one of the ring nitrogens. The thermal characteristics of two derivatives were evaluated. For instance, the N-allyl compound was a liquid with very low glass transition temperature, whereas the N-propargyl compound was a sticky solid at ambient temperature. The two compounds were both thermally stable according to STANAG 4582.
