abstract: |
The work focuses on the glycerol acetylation to triacetin over solid acid catalysts
in liquid and gas phase. Acidic catalysts such as ion-exchange resins and supported
heteropolyacids (HPA) were studied using toluene as an entrainer in batch-liquid phase.
The high activity of catalysts depends on acidity and Keggin structure stabilization
on the support. Low acidic catalysts like SiO2-based mixed metal oxides (TiO2, MgO,
ZrO2, SrO and Sc2O3) were evaluated in continuous-gas phase. The high activity of
SiO2-TiO2 catalyst seems to be related to the formation of Si-O-Ti bonds within the
SiO2.
