Process and apparatus for the diazotization of amines |
| abstract |
A process for the diazotization of a heterocyclic or a weakly basic benzenoid amine which comprises reacting together in a continuous manner, in a reaction zone from which a product stream containing diazotized amine is continuously removed, the amine and an aqueous solution of nitrite ions in the presence of sulphuric acid, the proportions and concentrations of the amine, the aqueous solution of nitrite ions and the sulphuric acid being so arranged as to provide a working acid concentration in the reaction zone in which the diazotized amine is stable. |
