실험 절차

A solution of 0.36 g of o-dianisidine dihydrochloride (1 mmole) in 45 ml (0.2 M HCl was cooled in an ice bath. To this was added dropwise (to keep the temperature below 5° C.) a solution of 0.17 g of sodium nitrite (2.46 mmole) in 5 ml distilled water. An orange color formed immediately. The mixture was stirred for another 30 minutes at 4° C. before using.
