Abstract (en)
[origin: WO2013192451A1] A process for converting 3-hydroxypropionic acid (3-HP) to acrylic acid is described. This process involves vaporizing an aqueous 3-HP solution, and contacting the 3-HP/water vapor with a catalyst or an inert surface area in a fixed bed reactor at a controlled temperature range, thereby converting the 3-HP to acrylic acid.
