Valorization of glycerol into fuel additives over zeolites as catalysts
Serafim, H.; Fonseca, I.; Ramos, A.; Vital, J.; Castanheiro, J.Acetalisation of glycerol with butanal has been investigated over a range of zeolites with different pore structures and acidity (USY with different Si/Al ratio, BEA and ZSM-5). The products of glycerol acetalisation were (Z + E)-(2-propyl-1,3-dioxolan-4-yl) methanol (five-member ring acetal) and (Z + E)- 2-propyl-1,3-dioxan-5-ol (six-member ring acetal). The results showed an optimum in activity for Si/Al rati...
