Abstract
This invention is related to the synthesis of organic carbonates from carbon dioxide and epoxides. It is particularly focused on the production of propylene cyclic carbonate from propylene oxide. The proposed catalytic materials includes a support made of aluminum oxyhydroxide (Catapal B®), nitric acid, acetic acid and/or phosphoric acid. An important stage is the physical and chemical conditioning of the catalytic materials and to this end, experimental methodologies such as spheronization and thermal treatments were implemented prior the evaluation process.
