A New Class of High-Density Fuels. 7-(N,N-Dialkylamino)-1,3,5-Triazaadamantanes (Diadam Fuels).
Abstract
A new class of high-density fuels has been synthesized - the 7-(N,N-dialkylamino)-1,3,5-triazaadamantanes (DIADAM fuels). They are readily prepared in high overall yield from inexpensive reactants including principally ammonia, formaldehyde, nitromethane, alkanals and hydrogen (55-60% by weight from ammonia and formaldehyde). Bipropellant systems using these fuels are hypergolic. The new fuels have several other desirable properties including high density, high hydrogen density, high specific impulse, and high volumetric heat of combusion. They are thermally stable and non-corrosive. Their high solubility in most solvents including benzene and water imparts added safety in the event of spillage. Compared to certain other high-density fuels they have relatively low viscosities and low pour points. A brief discussion of new ideas in fuel design, and a correlation between structure of the DIADAM fuels with selected physical properties (density, melting point, heat of combustion) are presented.
