Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | 2,2-Dimethylsuccinic acid | HCID 11701 | — |
| Solvent | Acetic Anhydride | HCID 7918 | — |
| Product | 2,2-Dimethylsuccinic anhydride | HCID 87067 | 84.4% |
Reaction Steps
50 g of 2,2-dimethylsuccinic acid and 70 ml of acetic anhydride were reacted at 140° C. for 3 hours and, after removing acetic acid and acetic anhydride under reduced pressure, the residue was subjected to vacuum distillation to obtain 37 g of 2,2-dimethylsuccinic anhydride.
