4. Carbonylation of acetylides
The process for synthesizing acrylic acid by hydroxycarbonylation of acetylene was developed by BASF and installed at Ludwigshafen (DE) on a scale of 110,000 t/year. The process is based on nickel-copper catalysis .
This process is now outdated, and all new acrylic acid capacities installed today use the process of direct oxidation of propylene to acrylic acid.
