반응 단계
A solution of ethyl acetoacetate (250 g.) and concentrated sulphuric acid (10 ml.) in isopropanol (1500 ml.) was heated at reflux for 3 hours. The solvent was removed by distillation, the residue was neutralised by treatment with barium carbonate, filtered and distilled under reduced pressure to give isopropyl acetoacetate (139 g.), b.p. 79°-82° C./20 mm Hg, in the form of a colourless liquid.
