Synthesis of jet fuel range high-density polycycloalkanes with vanillin and cyclohexanone

Abstract

In this work, jet fuel range high-density polycycloalkanes, dicyclohexylmethane and dodecahydrofluorene, were first synthesized by a two-step method with vanillin and cyclohexanone, two platform compounds that can be derived from...

Research progress of catalysts for aldol condensation of biomass based compounds

“…Haofei Gao 44 used titanium sulfate nanofibers (STNFs) as catalysts to catalyze the aldol condensation reaction between vanillin and cyclohexanone. The reaction route is shown in Fig.…”

Synthesis of biofuel precursors from benzaldehyde and cyclopentanone via aldehyde–ketone condensation in a deep eutectic solvent system

“…can be directly converted into biofuel precursors by the C-C coupling strategies, such as aldol condensation, hydroxyalkylation/ alkylation (HAA), Michael addition, benzoic condensation, Robinson annulation, etc., followed by hydrogenation or hydrodeoxygenation (HDO) to synthesize SLB with carbon numbers of C8-C22. [9][10][11][12] Huang et al successfully synthesized a biodiesel precursor (C15) from biomass-derived furfural and 2methylfuran through a HAA reaction. 13 However, biofuel precursors are typically hydrocarbons with short carbon chains, low density and caloric value, and poor low-temperature uidity, which cannot well meet the requirements of transportation fuels owing to the light molecules of BDPC with only 5 or 6 carbon atoms.…”

Synthesis of Renewable High-Density Fuel with Vanillin and Cyclopentanone Derived from Hemicellulose

“…The vanillin alcohol oxidase variant was selected to catalyze the conversion of vanillin alcohol to vanillin [ 32 ]. Vanillin and cyclohexanone undergo aldol condensation reaction and hydrodeoxygenation to obtain polycyclic alkanes of C 13 [ 33 ]. Polycyclic alkanes of C 12 were obtained through the aldol condensation reaction of vanillin and cyclopentanone, followed by hydrodeoxygenation [ 34 ].…”
