실험 절차

Into an ethanol solution (5 liters) comprising 500 g (3.67 moles) of anisaldehyde and 500 g (3.67 moles) of 4-hydroxyacetophenone was dropped an aqueous solution (600 ml) of 250 g of sodium hydroxide in about 80 minutes in a stream of nitrogen. Thereafter, the mixture was heated to 50° C. and agitated for 24 hours. The reaction mixture was cooled down to room temperature, to which were added 2 liters of 12% hydrochloric acid and then 4 liters of water, whereupon crystals settled. The crystals were collected by filtration and quickly washed with ethanol, followed by drying under reduced pressure to obtain 750 g of the intended compound (2.95 moles, yield 80%). The compound was recrystallized from ethanol to obtain light yellow prismatic purified crystals. The melting point and various spectral data of the compound coincided with those of a reference compound.
