DEHYDRATION OF 3-HYDROXYPROPIONIC ACID TO ACRYLIC ACID

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 t...

Zusammenfassung:	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. Procédé de conversion de l'acide 3-hydroxypropionique (3-HP) en acide acrylique, ledit procédé comprenant la vaporisation d'une solution aqueuse de 3-HP, et la mise en contact de la vapeur 3-HP/eau avec un catalyseur sur la surface inerte d'un réacteur à lit fixe dans une plage de températures contrôlée, pour convertir ainsi le 3-HP en acide acrylique.
