The 2-methylfuran (2-MF), easily obtained from furfural as a lignocellulosic biomass derivative, can be converted in good yields (70%) into 5,5-bis(5-methyl-2-furyl)pentan-2-one by condensation in the presence of mineral acids. This molecule is an important precursor for various interesting industrial products, such as benzofuranics with physiological activity and hydrocarbon mixtures useful as fuel components. In this work, the synthesis of 5,5-bis(5-methyl-2-furyl)pentan-2-one was successfully achieved (yield = 80%) via hydrolysis/condensation of 2-methylfuran, by using ethanol/water as solvent and Amberlyst (R) as a solid catalyst under moderate reaction conditions. Different polymeric ionic exchange resins were tested, conversion of 2-MF and product performances during reaction showed a proportional dependence to the capacity of proton exchange of resins. Amberlyst 15 presented the best results, and the resin can be regenerated and reused several times arriving to a constant product yield after the 3rd-4th reuse. Results attained for different zeolites tested indicate that 2-MF conversion appears to be function of pore size and channels structure of zeolite. These catalysts produced low yields of desired product mainly due to deactivation by the retention of intermediate reactions and products on the surface and inside pores. The use of H-Beta (F-) catalyst presenting a more hydrophobic surface could partially minimize catalytic deactivation. (C) 2015 Elsevier B.V. All rights reserved.
