Acrylic Acid from 3-Hydroxypropionic Acid

Stage: Development

3-hydroxypropionic acid is readily converted to acrylic acid by conversion to the acid salt followed by treatment with a solid oxide dehydration catalyst such as titania or alumina.



Further, conversion of 3-hydroxypropionic acid to the ammonium salt followed by dehydration leads to acylamide.

Excellent conversion and selectivity are observed in lab-scale flow reactors run continuously for several days.

Applications and Industries

Potential applications include: plastics, super absorbent polymers (diapers), detergents, thickening agents, coatings.
