Definitions
- the present invention is a process for the preparation of ⁇ , ⁇ -unsaturated carboxylic acids (for example acrylic or methacrylic acid) or a salt of ⁇ , ⁇ -unsaturated carboxylic acids, which comprises a process step in which a complex in a solvent in the presence of a halide is reacted, a composition comprising ⁇ , ⁇ -unsaturated carboxylic acid or its salt and halide ions, and the use of these compositions for the production of superabsorbent materials or as a monomer composition for the preparation of polymers, such as. B. polymethylmethacrylate.

KGaA, Weinheim; Wiley Online Library; DOI: 10.1002 / chem.201201757.
- the established catalytic cycle involves the steps of converting an olefin complex with C0 2 to the lactone complex, converting the lactone complex to the acrylate complex, and then exchanging the acrylate ligand with the olefin ligand to give the olefin complex.
- strong bases such as sodium butanolate or NaOH are used.
- a disadvantage of the use of these strong bases is that in a CO2 atmosphere they tend to react with the carbon dioxide to form carbonates and thus no longer be available for the catalytic conversion. To avoid this
