“…The 100% conversion of glycerol with selectivity of glycerol di-and tri-ethers higher than 92% in the etherification of glycerol with isobutene and over strong acid macroreticular ion-exchange resins as catalyst was achieved. Similar results were obtained by Melero et al (2008) who reported the results of etherification of glycerol with isobutene and sulfonic mesostructured silicas used as catalysts. They also obtained 100% conversion of glycerol and selectivity of glycerol di-and tri-ethers up to ca.…”

“…Melero et al 206 showed that sulfonic-acid-functionalized mesostructured silicas exhibited comparable or even superior catalytic activity to those displayed by the commercial composite nafion-silica (SAC-13). Under optimized reaction conditions, these mesostructured catalysts yield a complete glycerol conversion with selectivity towards di and tri-ethers up to ca.…”

In this work some relevant processes for the preparation of liquid hydrocarbon fuels and fuel additives from cellulose, hemicellulose and triglycerides derived platform molecules are discussed. Thus, it is shown that a series of platform molecules such as levulinic acid, furans, fatty acids and polyols can be converted into a variety of fuel additives through catalytic transformations that include reduction, esterification, etherification, and acetalization reactions. Moreover, we will show that liquid hydrocarbon fuels can be obtained by combining oxygen removal processes (e.g. dehydration, hydrogenolysis, hydrogenation, decarbonylation/descarboxylation etc.) with the adjustment of the molecular weight via C-C coupling reactions (e.g. aldol condensation, hydroxyalkylation, oligomerization, ketonization) of the reactive platform molecules.

Recebido em 4/5/10; aceito em 17/11/10; publicado na web em 14/3/11In esterification of oleic acid with methanol at 25 °C HPA displayed the highest activity. Moreover the HPA could be reused after being transformed into its cesium salt. In the reaction of etherification of glycerol HPA and Amberlyst 35W showed similar initial activity levels. The results of acid properties demonstrate that HPA is a strong protonic acid and that both surface and bulk protons contribute to the acidity. Because of its strong affinity for polar compounds, HPA is also seemingly dissolved in both oleic acid and methanol. The reaction in this case proceeds with the catalyst in the homogenous phase.
