在pH11.3的磁性介质中,二氧化硫脲可将芳香族硝基化合物还原为芳香族伯胺,经重氮化后与萘乙二胺反应生成红色的偶氮染料。
In the alkaline medium of pH 11 . 3 , thiourea dioxide can reduce aromatic nitro compounds to primary aromatic amines and the latters form red azo dyes with N - ( 1-naphthyl ) ethylenediamine dihydrochloride after diazotization with a maximum absorption at 525 nm .
