Aldol condensation of furfural and acetone over Mg Al layered double hydroxides and mixed oxides

Popis výsledku v původním jazyce

Liquid phase aldol condensation of furfural and acetone catalyzed by solid base catalysts (Mg Al hydrotalcites and Mg Al mixed oxides) has been investigated as a method to valorize short chain ketones obtainable from biomass pyrolysis for the productionof higher-molecular-weight products usable as fuel components. The Mg/Al molar ratios of the investigated catalysts was varied in the range from 2 to 4 and their catalytic activity was tested at different reaction temperatures (20?100 °C) using several activation methods. Mg Al hydrotalcites were used either after calcination as mixed oxides or after subsequent contact with liquid water or steam as rehydrated materials. Both furfural-acetone condensation products, i.e. C8 and C13, were the desired products of aldol condensation reaction. Higher reaction temperature facilitated the dehydration step and enhanced the catalyst selectivity to both dehydrated products (C8 and C13). The best results were achieved with calcined catalyst sample
