Abstract
New energy-intensive compounds 4,8-dicyanomethyl-4H,8H-difurazano[3,4-b:3',4'-e]piperazine (DCMFP) and 4,8-ditrazolomethyl-4H,8H-difurazano[3,4-b:3',4'-e]piperazine (DTMFP) have been synthesized for the first time. The synthesis of these compounds is described. Both compounds were studied as possible dispersants of solid fuels for gas generator engines, their densities, enthalpies of combustion and formation, sensitivity to impact and friction were determined (for DCMFP, the sensitivity is very low, at the level of TNT; for DTMFP, at the level of HMX), the ballistic efficiency of solid fuels was estimated based on DCMFP and DTMFP (against 7-amino-7 -difurazano[3,4-b:3',4'-f]furoxano[3'',4''-d]azepine, Az(O)NH2 the first wins 4%, the second loses ). A comparison was also made with a number of other dispersants developed over the past few years. Preliminary testing of DCMFP and DTMFP for thermal stability was carried out by DTA in a nonisothermal mode, it was shown that these components are very stable, the so-called temperature of the beginning of intensive decomposition is 312 and 270°C, respectively.
