Participants

Reaction Steps

A solution of 60.0 g of 2-phenylcyclohexanone in 400 ml of ethanol is stirred and treated with 160 ml of 15% aqueous sodium hydroxide and 53.0 g of benzaldehyde. The solution is stirred at room temperature and the product begins to separate from the solution as an oil after 30 minutes. The mixture is seeded with crystalline material and allowed to stand for about 16 hours at room temperature. The resulting slurry is poured onto 1.5 l. of ice-water, allowed to stand at room temperature for 2 hours, filtered and washed with cold water to yield 81.2 g of material, melting point 75°-78° C. After crystallization from 200 ml of isopropanol, the product weighs 62.1 g, melting point 85°-87° C. A small sample, recrystallized from ethanol, melts at 86°-88° C.
