The recent progress in the development of advanced aircraft, racing engines, and military vehicles makes a challenge for seeking the next generation of high-energy-density hydrocarbon fuels.Fuels challenge.
Meanwhile, it is a well-known problem to produce a fuel with a high energy content and suitable low-temperature properties. For example, often high-energy density liquid fuels exhibit high freezing points. Regarding possible increased costs of synthetic high-energy-density liquid fuels, enhanced energetic properties become of crucial importance. The possibility of using the smaller fuel tanks, provided by high volumetric heat of combustion, can give benefits that may outweigh the higher costs of this type of fuel.Cyclic hydrocarbons-based fuels.
We have prepared a number of hydrocarbons containing two norbornane moieties or norbornyl and cyclopropyl groups from commercially available 5-vinyl-2-norbonene. The synthesis of these hydrocarbons is simple and it uses well-known tools of organic chemistry like the Diels-Alder reaction and cyclopropanation reaction. The altering of the structure of norbornane-type hydrocarbons allowed us to combine two contradictory properties: high fuel density + low freezing point
At the same time, the energy density was noticeably higher than that of the related fuel, JP-10. Altogether these factors make norbornene-based fuels the possible fuel for the future's needs.Learn more in the related papers:Synthesis and properties of high-energy-density hydrocarbons based on 5-vinyl-2-norborneneMetal chlorides supported on silica as efficient catalysts for selective isomerization of endo-tetrahydrodicyclopentadiene to exo-tetrahydrodicyclopentadiene for JP-10 producing
