Citraconic Anhydrides → HCID 67073065, compound

Participants

Reaction Steps

A 2.5-liter glass resin kettle was charged with 136.2 g (1.0 mole) of m-xylylenediamine and 2000 ml of reagent acetone and flushed with nitrogen. The kettle was fitted with a dropping funnel, reflux condenser, mechanical stirrer and thermocouple. The addition funnel was charged with 246 g (2.2 moles) of citraconic anhydride which was slowly added over a 21/2-hour period, with stirring and refluxing the acetone. The reaction mixture was allowed to cool to room temperature with stirring. Suction filtering and acetone wash of the solid product (air-drying) gives a 246 g of a tan powder, melting at 148°-150° C. The structure was confirmed by NMR analysis.
