Abstract
Provided herein are heterogeneous catalysts suitable for use in carbonylation reactions, including the production of acrylic acid from ethylene oxide and carbon monoxide on an industrial scale. The production may involve various unit operations, including, for example: a beta-propiolactone production system configured to produce beta-propiolactone from ethylene oxide and carbon monoxide; a polypropiolactone production system configured to produce polypropiolactone from beta-propiolactone; and an acrylic acid production system configured to produce acrylic acid with a high purity by thermolysis of polypropiolactone.
Claims31
A compound, comprising:
- a solid support;
- at least one ligand coordinated to a metal atom to form a metal complex;
- at least one anionic metal carbonyl moiety coordinated to the metal complex;
- and
- at least one linker moiety covalently tethering the ligand to the solid support.
