| titleOfInvention | Process for Preparing 3-Hydroxy Propionic Acid and Salt from Exopide Derivative |
| abstract | The present invention is to prepare a β-hydroxy ester by the carbonylation reaction of the epoxide derivative, the 3-hydroxy propionic acid by hydrolysis reaction of the β-hydroxy ester in the presence of an acid or a base (3-hydroxy propionic acid) Or a process for preparing 3-hydroxypropionic acid salts. The process for preparing β-hydroxyesters from epoxide derivatives comprises the steps of (a) using a catalytic amount of cobalt compound and an effective amount of promoter to bring epoxide, carbon monoxide and alcohol in a solvent at a temperature of 30 to 150 ° C. and 50 to 3000 psig. Reacting at a pressure of to produce β-hydroxyester as an intermediate and its derivative at 2 to 98 wt%; (b) separating the product and solvent from the catalyst and promoter. Hydrolyzing the β-hydroxyester to prepare 3-hydroxy propionic acid or 3-hydroxypropionic acid salt is (c) the separated product and the solvent in the presence of an acid or a base The reaction is carried out under to prepare 3-hydroxy propionic acid or a salt thereof. Acidic or alkaline resins may be used in place of the acids or bases. |
