Catalysts and processes for the conversion of succinates to citraconates or itaconates |
摘要 |
Processes for producing citraconic anhydride and citraconic acid using porous materials with specific surface acidities and surface areas are described. The preferred catalyst is a porous gamma alumina. Itaconic acid is produced from citraconic acid. Itaconic acid is an intermediate to a variety of compounds including polymers.
