Furfuryl alcohol in synthesis of levulinic acid esters and difurylmethane with Fe and Rh complexes

The possibility of synthesis of levulinic acid esters by the reaction of furfuryl alcohol with aliphatic alcohols in the system CCl4-Fe(acac) 3 was studied.

Catalyst-free synthesis of biodiesel precursors from biomass-based furfuryl alcohols in the presence of H2O and air

Production of biodiesel from biomass resources usually requires elongation of carbon numbers from typical C5 and C6 platform molecules through C-C coupling reactions, which were catalyzed by acid, base or metal catalysts traditionally. Herein, a catalyst-free method was developed to produce bis(furan-2-yl)methane derivatives (BFMs) from furfuryl alcohol derivatives (FAs) in the presence of H2O and air without any other additional catalysts. An 81% yield of bis(5-methylfuran-2-yl)methane (BMFM) can be obtained from 5-methylfurfuryl alcohol (5-MFA) and a 59% total yield of C11 biodiesel was obtained from 5-methylfurfural (5-MF). In addition, a H2O and air mediated free radical decarboxylation mechanism was proposed based on the detailed mechanistic studies. This strategy offers a green, low-cost and environmentally friendly approach to synthesize biodiesel precursors from biomass based platform molecules.

A one-pot conversion furfural, 5 - hydroxymethyl furfural furan

A one-pot conversion furfural, 5 - hydroxymethyl furfural furan method, characterized by comprising the following steps: the furfural, 5 - hydroxymethyl furfural, catalyst, solvent are added in the reactor with a condensation device, in an inert atmosphere, in the 80 - 250 °C reaction temperature, stirring, reaction 0.5 - 30 h, ice water bath cooling. The invention will be furfural, 5 - hydroxymethyl furfural two substrates through a pot conversion of furan, simplify operation process, avoiding the loss of the material and the step of, maximum utilization of resources; in suitable process conditions, greatly shortens the reaction time, the production cost is reduced, thereby improving the production efficiency; in the normal pressure on the temperate conditions, high expectations for production equipment, in accordance with the principles of safe production; and forming the lignin is suitable for pre-treatment of wood cellulose acid or catalytic generation of furfural, 5 - hydroxymethyl furfural mixture one-pot conversion of furan, to proceed from the biomass resources for producing tetrahydrofuran.
