실험 절차
2-nitro-2'-hydroxy-3',5'-di-t-butylazobenzene 23.7 g was added to a mixture of n-octanol 50 g, water 14 g and 97% sodium hydroxide 8.2 g, and the resultant mixture was heated to 65° C. The mixture was then cooled to 50° C., and 9-fluorenone 2.0 g was added thereto. The resultant mixture was stirred at 90°~97° C. for 2 hours, thus almost all of the azobenzene having disappeared to produce 2-(2-hydroxy-3,5-di-t-butylphenyl)benzotriazole-N-oxide. Thus, the reaction of Process (b) was completed.
