Some measured thermal properties of new high-energy-density caged hydrocarbon compounds

Abstract

A new class of pentacyclic hydrocarbon compounds with high-energy/high density have been synthesized to be used as fuels or fuel additives, with the expectation that their inclusion in the fuel mixture will result in a net increase in volumetric efficiency of the current generation of powerplants. These compounds exhibit high density (rho = 1.2-1.3 g/cu cm) and contain a moderate amount of strain energy, which contributes to the energy output during combustion. Through direct measurements, melting and boiling points, specific heats, and latent heats of fusion were determined. Droplet combustion experiments with binary solutions of solid high-energy fuels in kerosene indicated increased effervescence and higher heat output. The liquid high-energy-density-formulations exhibited microexplosive combustion behavior. (Author)
