Reaction Steps
97% sodium hydroxide 14.4 g was added to a mixture of methanol 72 ml and water 36 ml, 2-nitro-2'-hydroxy-5'-t-butylazobenzene 15.0 g was then added to the resultant mixture and the mixture was heated to 45°~50° C. Hydroquinone 0.4 g and then glucose 5.0 g were added to the heated mixture over 30 minutes while stirring. The mixture was further stirred for one hour. As this result, the azobenzene disappeared to produce 2-(2'-hydroxy-5'-t-butylphenyl)benzotriazole-N-oxide.
