Provided is a continuous synthesis method for 1,1-bicyclic[1.1.1]pentane-1,3-diethyl ketone compounds. The continuous synthesis method comprises: under the irradiation of a light source, continuously conveying raw material A and raw material B to a continuous reaction device for a continuous photochemical reaction to obtain 1,1-bicyclic[1.1.1]pentane-1,3-diethyl ketone compounds, and controlling the reaction temperature in the continuous reaction device by a temperature control device during the continuous photochemical reaction. A propellane with substituents, as a reaction raw material, is subjected to the above photochemical reaction in the continuous reaction device to reduce the probability of its slow decomposition and deterioration under the irradiation, and greatly improve the conversion rate of the reaction material and product yield.

A method to generate dense, multi-cyclic diamondoid fuels from bio-derived sesquiterpenes. This process can be conducted with both heterogeneous and homogenous catalysts and produces the targeted isomers in high yield. The resulting multi-cyclic structures impart significantly higher densities and volumetric net heats of combustion while maintaining low viscosities which allow for use at low temperature/high altitude. Moreover, bio-derived sesquiterpenes can be produced from renewable biomass sources. Use of these fuels will decrease Navy dependence on fossil fuels and will also reduce net carbon emissions.
