Reaktionsschritte
To a solution of 0.97 g of sodium hydroxide in 9.7 ml of water was added 27.1 ml of ethanol. A solution of 2.563 g of p-methylacetophenone in 4 ml of ethanol was added dropwise to the mixture, followed by dropwise addition of a solution of 2.30 g of p-methylbenzaldehyde in 4 ml of ethanol. The resulting mixture was stirred at room temperature for 3.75 hours, and the solid matter was filtered, washed with cold water and ethanol and thoroughly desiccated to give 4.16 g of 4,4'-dimethylchalcone.
