Synthesis of alkenyl succinic anhydrides from methyl esters
Alkenyl succinic anhydrides (ASA) have been prepared by ene-reaction of high-oleic sunflower oil methyl esters with maleic anhydride in a 50 xylene medium |
- Succinic anhydride formation occurs.
Step 3: Acetic anhydride makes it easier to form anhydride The reaction is easier in the presence of acetic anhydride because the leaving group is the acetate ion, which is less basic than hydroxide ion and the best leaving group.
What is the chemical synthesis of succinic acid?
Succinic acid can be produced via catalytic hydrogenation of maleic acid or maleic anhydride, a process that is both expensive and harmful to the environment.
It could also be produced via fermentation.
What is the mechanism of succinic anhydride?
Succinic anhydride results from the intramolecular transformation of the hydride complex of palladium and maleic anhydride.
The palladium hydride complexes detected in the contact solution apparently play the crucial role in the conjugation of oxidation, reduction, and addition type reactions.4 déc. 1997
What is the process carried out to convert succinic acid to succinic anhydride?
The process carried out to convert succinic acid to succinic anhydride is Hydration.
