Reaction Steps
2-nitro-4-chloro-2'-hydroxy-3',5'-di-t-butylazobenzene 26.0 g and 9-fluorenone 2.0 g were added to a mixture of isopropyl alcohol 80 g, water 14 g and 97% sodium hydroxide 11.0 g, and the resultant mixture was stirred at the boiling point of 79° C. for 8 hours to effect reaction, thus almost all of the azobenzene having disappeared to produce 2-(2-hydroxy-3,5-di-t-butylphenyl)-5-chlorobenzotriazole-N-oxide. Thus, the reaction of Process (b) was completed.
