Process for synthesis of acrylic acid precursors via hydroformylation of vinyl ether |
| abstract |
A process is disclosed for the preparation of acrylic acid precursors by a hydroformylation process which comprises reacting a vinyl ether with carbon monoxide and hydrogen in the presence of a catalyst comprising a rhodium carbonyl compound and a phosphine ligand at a mild temperature and pressure until there is substantial formation of the intermediate 2- and 3-ethoxypropanals, followed by oxidation of said aldehydes and pyrolysis to said acrylic acid. |
