Web1. The method of diazotizing aromatic primary amines which comprises carrying out the diazotization reaction with an aqueous sulfuric acid solution of the amine in the presence of nitrous acid and in the presence of between about 20% and 500% of a water-soluble metallic chloride salt by weight of the amine to be diazotized. 2. WebIn practice, air is bubbled through a cooled (-5° C.) aqueous acid containing aniline. This solution absorbs nitric oxide from a reservoir at one atmosphere of pressure and the aniline diazonium ion is produced. Table 3 presents the results of the diazotization procedure for a series of amines illustrated in Reaction Scheme 2.
