Acetic Anhydride → 2,3-Dimethylsuccinic anhydride

Participants

Reaction Steps

2,3-Dimethyl succinic anhydride was prepared as described in Sutton, et al. OPPI 24 (1992) 39. Briefly, 7.1 g 2,3-dimethyl succinic acid and 6.9 ml acetanhydride were slowly heated up to 50° C. for 3 hours. Then acetanhydride was removed by distillation. The product was recrystallized from ethanol abs. and characterized by the melting point.
