Abstract
There is provided a method for synthesizing an alkenoic acid, in particular acrylic acid comprising the step of oxidizing an alkenyl alcohol in the presence of a metal oxide catalyst to form the alkenoic acid. The invention further provides a step of deoxydehydrating a polyol, including glycerol to obtain said alkenyl alcohol including an allyl alcohol.
Claims18

-11. (canceled)
A method for synthesizing an alkenoic acid from a polyol comprising the steps of:
- (a) deoxydehydrating the polyol in the presence of a carboxylic acid to form an alkenyl alcohol;
- and
- (b) oxidizing the alkenyl alcohol in the presence of a metal oxide catalyst to form the alkenoic acid, wherein said metal oxide catalyst has the formula MoxVyWmOd
