| 摘要 |
An object of the present invention is a membrane catalyzer for the synthesis of acrylic acid from glycerol, the preparation of the membrane catalyzer and its use for the preparation of acrylic acid from glycerol. Said membrane catalyst comprises a first layer A 10 [sic] composed of a phase capable of selectively converting acrolein into acrylic acid, and a second layer B formed on said first layer A, composed of an acid phase having a Hammett acidity H0 of less than +2, capable of selectively performing the glycerol into acrolein dehydration reaction. |
