ABSTRACT:
A process is described for the production of a suspension of cyanuric chloride in an aqueous liquid, more particularly, water. Molten cyanuric chloride is sprayed using a spray arrangement comprising a spray nozzle immersed in the aqueous liquid. Blockages in the nozzle during the critical start and stop phases are avoided by passing superheated steam through those parts of the spray arrangement which come into contact with the cyanuric chloride melt before and after the spraying process. A particularly reactive cyanuric chloride suspension is obtained by spraying a mixture of cyanuric chloride melt and superheated steam.
