Versuchsvorschrift

2,6-di tert.butyl-4-aminophenol was prepared by hydrogenating a mixture of 23.5 grams of 2,6-di tert.butyl-4-nitrosophenol, 2 grams of 5% Palladium on carbon, and 200 milliliters of absolute ethanol in a Parr Pressure Reaction Apparatus. The reduction was accomplished in 1 hour at a maximum hydrogen pressure of 50 psi and a maximum temperature of 50° C. The resulting solution of 2,6-di tert.butyl-4-aminophenol was removed from the Pressure Apparatus and filtered to remove the catalyst.
