실험 절차

A solution of 100 g piperonal in 900 ml acetone was stirred at room temperature with 15 ml of 10% aqueous sodium hydroxide and 30 ml of water. After 3 hours 5 ml of acetic acid was added and the reaction mixture was evaporated. The residue was recrystallized from methanol and dried in vacuo to yield 60 g of piperonalacetone, m.p. 104°-105° C. (EtoAc).
