실험 절차

To a slurry of 97.0 g of benzil in 1 liter of 95% EtOH was added 20 g of sodium borohydride. After stirring 10 minutes, the mixture was diluted with 1 liter of water and the mixture was treated with activated carbon. The mixture was then filtered trough supercel and the filtrate heated and diluted with an additional 2 liters of water until it became slightly cloudy. The mixture was then cooled to 0 to 5° C. and the resulting crytals were collected and washed with cold water. The crystals were then dried in vacuo.
