Experimental determination of the standard enthalpy of formation of 4H,8H-bis(furazano)[3,4-b:3′,4′-e]pyrazine and evaluation of its performance as a dispersant of solid fuels

Abstract

The energy of combustion ΔH^°_c of 4H,8H-bis(furazano)[3,4-b:3′,4′-e]pyrazine (BFP) was measured by calorimetry in the oxygen atmosphere and the standard enthalpy of formation ΔH^°_f was calculated. The real ΔH^°_f value was found to be 33 kJ mol⁻¹ higher than reported before. The obtained results were used for correction of the evaluated efficiency of using BFP as a solid fuel dispersant for rocket ramjet engines, which showed high BFP performance.
