ABSTRACT:
Process which comprises feeding an aromatic amine in the presence of HF to a reaction zone simultaneously with a diazotizing agent so as to effect diazotization of the aromatic amine, thermally decomposing the resulting diazonium salt substantially as it is formed, and removing the resulting fluoroaromatic compound from the reaction zone substantially as it is formed. The amine and the diazotizing agent are fed to the reaction zone in such quantities and proportions that they are consumed substantially as fed so that no substantial concentration of either builds up in the reaction zone.
