Different ketones such as cyclohexanone, cyclopentanone, acetophenone, 2-acetonaphthalene, 4-methylcyclohexanone in the presence of anhydrous CuCl 2 (catalytic amounts) at reflux condition for 2-4 hours, without using a solvent led to dimers 2-(1-cyclohexane-1-yl)-cyclohexanone 6, 2-cyclopentylidene cyclopentanone 10, trimer dodecahydrotriphenylene (DTP) 4, trindan (tricyclopentabenzene) 9,1,3,5-triphenylbenzene (TBP) 12a, 1,3,5-triss-naphthylbenzene 12b and dodecahydro-2,6,10- trimethyltriphenylenes 17 and 18.

Transferring biomass-derived cyclic ketones such as cyclopentanone and cyclohexanone to a mono-condensed product through aldol self-condensation has great potential for the synthesis of a renewable high-density fuel. However, the selectivity is low for numerous catalysts due to the rapid formation of di-condensed by products. Herein, MIL-101-encapsulating phosphotungstic acid is synthesized to catalyze the self-condensation with selectivity of more than 95%. PTA clusters are uniformly dispersed in MOF cages and decrease the empty space (pore size), which provides both acidic sites and shape-selective capability. The optimal PTA amount decreases corresponding to the increase of reactant size. The shape-selectivity is also realized by changing the pore size of MOF such as from MIL-101 to MIL-100. Moreover, the catalyst is resistant to PTA leaching and performs stably after 5 runs. After hydrodeoxygenation of the mono-condensed product, high-density biofuels with densities of 0.867 g ml-1 and 0.887 g ml-1 were obtained from cyclopentanone and cyclohexanone, respectively. This study not only provides a promising route for the production of high-density biofuel but also suggests the advantage of MOF-based catalysts for shape-selective catalysis involving large molecular size.
