Cyclopentanone: A raw material for production of C15 and C17 fuel precursors

Aqueous phase hydrogenation of furfural to furfuryl alcohol over Pd–Cu catalysts

“…This will significantly reduce the energy needed for production of furfural feedstock. For example, diluted aqueous solutions of furfural can be highly selectively converted to cyclopentanone [2] or C 15 and C 17 fuel precursors [19]. In a recent publication [20] we have demonstrated highly selective catalytic conversion of furfuryl alcohol to cyclopentanone (more than 90 mol% yield) in water as the solvent at mild reaction conditions.…”

Carbon supported Pd–Cu catalysts for highly selective rearrangement of furfural to cyclopentanone

“…Potentionally, it 8 can be used for preparation of polyamides [17], C15-C17 diesel or jet fuels [18] and polyolefin 9 stabilizers [19]. Cyclopentanone can be prepared by the catalytic vapor-phase cyclization of 1, 10 6-hexanediol [20] or adipic acid esters [21][22][23] or by the liquid phase oxidation of 11 cyclopentene with nitrous oxide [24,25].…”

Bio-derived fuel additives from furfural and cyclopentanone

“…The 2,5-bis(2-furylmethylidene)cyclopentan-1-one was prepared according to the method described in [30]. Commercial Pd/C, Pt/C and Ru/C catalysts with 5 wt.% metal loading were purchased from AlfaAesar.…”

“…These condensation reactions proceed very rapidly and highly selectively in diluted aqueous solutions of hydroxides (furfural:NaOH = 16:1 mol) at about 40°C and 90 min; e.g. 2,5-bis(2-furylmethylidene)cyclopentan-1-one (F 2 C) is produced in yields more than 95 mol% [30]. The resulting condensation products are solids insoluble in water, i.e.…”
