ABSTRACT:
Three substituents are introduced into cyanuric acid in the presence of an acid binding agent by working in a manner permitting high mixing and therefore high reaction velocities and permitting high throughputs in small tubular containers by introducing liquid cyanuric chloride through a nozzle in the upper portion of the mixing apparatus in countercurrent flow to upwardly flowing reactants (and acid binding agent) introduced from at least one lower nozzle above a breast shaped constriction in the lower, open portion of the apparatus. The process can be carried out at normal, reduced or elevated pressure.
