Diazotization of sulfanilic acid mechanism
WebThe reaction of primary aromatic amines with nitrous acid, at low temperature, results in the formation of diazonium salts. This reaction is known as diazotization. The diazotization … WebThe reaction starts by diazotization of sulfanilic acid with sodium nitrite. The diazonium salt is then immediately used to react with N,N-dimethylaniline in an reaction of electrophilic aromatic substitution to form methyl orange. ... hand-written reaction mechanism of methyl orange synthesis starting from sulfanilic acid, sodium salt and ...
