Abstract
In the present method a reaction mixture is comprised of a source of adamantane, mixed with an alkane or cycloalkane. A Lewis acid catalyst is added to the reaction mixture which is heated and then purified. The resulting alkyl diamondoid mixtures have significantly higher densities and volumetric net heats of combustion while maintaining low viscosities which allow for use at low temperature.
