ABSTRACT OF THE DISCLOSURE Production of cloro-amino-s-triazines by means of the conventional reaction of cyanuric chloride with amines or .alpha.- amino-nitriles in the presence of an acid-binding agent but in such a way that the reaction is carried out with high mixing rates and thus high reaction rates and that large throughputs can be obtained in small tubular vessels when liquid cyanuric chlor- ide is injected through a nozzle, which is installed in the upper part of a mixing device, in a countercurrent to the reactants (+ the acid binding agent) rising upwardly from a nozzle or nozzles. The nozzle or nozzles for the reactants are installed above a breast-like taper in the lower open part of the device. The process can be carried out at standard pressure and at excess or negative gauge pressure.
