Synthesis of Zn/Al mixed-oxide catalyst for…
Conclusions
We prepared Zn/Al mixed oxides by the coprecipitation and the hydrothermal
method. The physical properties of the prepared Zn/Al mixed oxides were
investigated, as well as their activity as catalyst for synthesis of glycerol carbonate
by carbonylation of glycerol with urea. The Zn/Al mixed oxides prepared by the
coprecipitation method without NaNO3 showed the highest catalytic activity in
synthesis of glycerol carbonate. The conversion of glycerol increased with
increasing catalyst basicity, and the selectivity for GC increased with increasing
diffraction peak intensity.
