The invention relates to an alkyl-substituted polycyclic biomass high-density aviation fuel and a preparation method thereof, wherein cyclopentanone reacts with dimethyl carbonate under basic conditions to obtain 1,3 -dicarbonyl compound 1 with a double five-membered ring. Compound 1 and haloalkane and cycloalkenone are reacted with solvent-free nucleophilic substitution/Michael addition of a two-step one-pot, and HDO precursor compounds are synthesized. The Pd / C catalyst was used to react HDO at high temperature and high pressure to obtain a series of polycyclic high density liquid hydrocarbon fuel compounds having an alkyl substitution. The synthetic route disclosed by the invention is simple in reaction, mild in condition, high in yield and wide in substrate range, and the synthesized fuel has higher density. The volume heat value and the lower freezing point can be applied to various aircrafts or as additives to improve the flight performance of the aviation fuel. (by machine translation)
