|Abstract:||The following porous aluminosilicates were tested as acid catalysts in the reaction of furfuryl alcohol (FA) with ethanol, at 140 C: micro/mesoporous composite Beta/TUD-1 and the correspondent nanocrystalline (large pore) zeolite H-Beta; ITQ-2 and its zeolite counterpart (medium pore) H-MCM-22; mesoporous Al-TUD-1. The target product ethyl levulinate (EL) was formed with a yield up to 80%, at 24 h reaction (100% FA conversion). Relationships between the catalytic results and the acid and texture properties of the catalysts were established. Comparative studies for the aluminosilicates and the well-known sulfonic acid resin AmberlystTm-15 were reported on the basis of EL yields, the undesirable formation of diethyl ether, and catalyst stability (regeneration and reuse). A study of the reaction products was carried out by comprehensive two-dimensional gas chromatography combined with time-of-flight mass spectrometry. (C) 2013 Elsevier B.V. All rights reserved.|
