PROCESS FOR THE CARBONYLATION OF ACRYLIC ACID |
| abstract |
The present invention relates to a process for the preparation of methylmalonic acid by carbonylation with carbon monoxide of acrylic acid, in basic solution and in the presence of a carbonyl derivative of iron. Methylmalonic acid is used in particular for the preparation of pterosin C or in the formulation of special coatings. |
