Versuchsvorschrift

The same procedure as in Example 7 was repeated, except that secondary butanol 80 g was replaced by n-octanol 50 g, and that 2-nitro-2'-hydroxy-5'-t-butylazobenzene 19.9 g was replaced by 2-nitro-2'-hydroxy-3',5'-di-t-butylazobenzene 23.7 g, thus producing 18.7 g of 2-(2-hydroxy-3,5-di-t-butylphenyl)benzotriazole-N-oxide having a melting point of 168° to 171° C. at the yield of 83.0%.
