ABSTRACT:
Zwitterionic diazonium salts, derived from aromatic amines, are aggregated by: (a) diazotizing said amine to a zwitterionic diazonium salt in the presence of a cationic surfactant or (b) diazotizing said amine and thereafter treating the resulting zwitterionic diazonium salt with a cationic surfactant, so as to give particles of the diazonium salts which are readily separable from the liquid mass in which they are formed.
