Process for preparing acrylic acid from methanol and acetic acid |
| abstract |
A process for preparing acrylic acid from methanol and acetic acid, comprising (i) contacting a gaseous stream S 0 comprising methanol, oxygen and inert gas with an oxidation catalyst to obtain a gaseous stream S 1 comprising formaldehyde and inert gas; (ii) removing at least a portion of the inert gas present in S 1 from at least a portion of the formaldehyde present in S 1 by absorbing this formaldehyde in an absorbent to obtain a gaseous stream S 2 comprising the portion of the inert gas removed, and to obtain a stream S 3 comprising absorbent and absorbate comprising formaldehyde; (iii) optionally removing a portion or the entirety of the absorbent present in stream S 3 , such that a stream S 3 a remains from stream S 3 , and producing a stream S 4 from at least stream S 3 or stream S 3 a and a stream S 5 comprising acetic acid; and (iv) contacting stream S 4 in gaseous form with an aldol condensation catalyst to obtain a gaseous stream S 6 comprising acrylic acid. |
