実験手順

A solution of 14 g of 3,4-dichlorobenzaldehyde in 65 ml of acetone is diluted with 435 ml of water and treated with a solution of 5 g of sodium hydroxide in 50 ml of water. The mixture is stirred for 48 hr, extracted with benzene, dried and concentrated in vacuo to give 3,4-dichlorobenzalacetone as an oil which crystallizes on standing.
