Succinic anhydride from ethylene oxide |
| abstract |
Continuous flow systems and methods produce succinic anhydride by a double carbonylation of ethylene oxide with carbon monoxide and at least one catalyst. In some embodiments, the double carbonylation occurs using a single catalyst. In other embodiments, a first catalyst is used to promote the first carbonylation, and a second catalyst different from the first catalyst is used to promote the second carbonylation. The succinic anhydride is isolated from the product stream by crystallization and the catalyst is recycled to the reaction stream. |
