ABSTRACT OF THE DISCLOSURE The present invention provides for the production of optionally substituted 2-mercapto-4,6-dichloro-s-triazines by means of the conventional reaction of cyanuric chloride with mercaptans or mercaptides in the presence of an acid-binding agent but in such a manner that high mixing rates and thus high reaction rates can be used and that large throughputs can be attained in small tubular vessels when liquid cyanuric chloride is injected through a nozzle, which is installed in the upper end of a mixing device, in a countercurrent to the reactant (+ the acid-binding agent) rising upwards from a nozzle or nozzles. The nozzle or nozzles for the reactants are installed above a breast- like taper in the lower open end of the device. The process can be carried out at standard pressure, excess pressure or at negative gauge pressure.
