Progresses in the synthesis of acrolein,including the routes of formaldehyde and acetaldehyde condensation,propylene oxidation,propane oxidation,and glycerin dehydration et al,and the catalysts for above synthetic reactions are presented and compared.

H3PW12O40/SiO2 heteropoly acid catalysts were prepared by incipient wetness impregnation with SiO2 as support,and their catalytic performances for glycerol dehydration to acrolein were evaluated in a fixed-bed continuous flow reactor under atmo-spheric pressure.
