反応手順
o-Anisalacetone is prepared by adding 70 ml of 10% aqueous sodium hydroxide to 7.7 moles of acetone, 280 ml of water, and 2.8 moles of o-anisaldehyde, slowly with cooling to maintain the temperature in the range of 25°-31° C. Another 2 hours stirring followed by acidification, separation of layers, dehydration with acid in benzene at reflux, and finally distillation at reduced pressure gives the crude o-anisalacetone.
