Versuchsvorschrift

2,6-di tert.butyl-4-aminophenol was prepared by adding in a nitrogen atmosphere, a solution of 70 grams of sodium dithionate in 300 milliliters of water to a mixture of 23.5 grams of 2,6-di tert.butyl-4-nitrosophenol, 80 milliliters of 5 N sodium hydroxide solution and 160 milliliters of water. The addition was accomplished in 45 minutes at 24° C. to 41° C. After stirring for 21/4 hours, 100 milliliters of benzene was added to dissolve the solid product, and the layers were separated.
