Abstract (en)
[origin: WO2009081021A1] The invention provides a technology for producing acrolein from glycerol while maintaining high reagent partial pressures, which leads to a higher yield. The invention more particularly relates to a method for producing acrolein from glycerol that comprises the intermediate step of forming glycerol and acrolein cyclic acetals.
