摘要： Finely divided suspensions of cyanuric chloride in organic solvents which are practically water free are prepared at high mixing velocities and low temperatures by introducing liquid cyanuric chloride through a nozzle in the upper portion of the mixing apparatus in countercurrent flow to upwardly flowing solvent introduced from at least one lower nozzle above a breast shaped constriction in the lower open portion of the apparatus. In this way the chamber walls are always covered with an unbroken layer of liquid. The process can be carried out at normal, reduced or elevated pressure. At reduced pressure by evaporation of the solvent there is simultaneously a cooling of the system.
