Participants

Reaction Steps

To a solution of 345 g (2.65 mols) propionic anhydride and 1.05 g concentrated sulfuric acid maintained at 45°-50° C was added dropwise 140 g (2.5 mols) acrolein over a period of 15 minutes. The reaction mixture was stirred for an additional 10 minutes. A 2.6 g-sample of 2,4,6-trimethyl-pyridine was then added and the reaction mixture stirred at about 25° C. for about 17 hours. The reaction mixture was then distilled through a short column to give 268 g of the product as a slightly yellow liquid, b.p. 96°-101° C (0.25 mm Hg).
