  • Glycerol conversion into biofuel additives by acetalization with pentanal (cas 27154-67-2) over heteropolyacids immobilized on zeolites
  • Add time:07/12/2019         Source:sciencedirect.com

    Dodecamolydbophosphoric acid (HPMo) immobilized on USY zeolite was used as a catalyst for the acetalization of glycerol with pentanal (cas 27154-67-2) at 70 °C. Catalysts were prepared with different amounts of heteropolyacid, and the most active sample was the [email protected] catalyst (1.1 wt.%). The products of glycerol acetalization with pentanal were (2-butyl-1,3-dioxolan-4-yl)methanol, a five-member ring compound, and 2-butyl-1,3-dioxan-5-ol, a six-member ring compound. Good values of selectivity for the five-member ring compound (80–85%) were obtained with all materials. The reaction conditions were optimized using [email protected] as a catalyst. The optimal conditions were determined to be 70 °C reaction temperature with 0.3 g catalyst and a 1:2.5 M ratio of glycerol to pentanal.The catalytic stability of [email protected] was studied. The acetalization of glycerol with pentanal was performed using the same sample. High catalytic activity for [email protected] was observed.
