Abstract

The present invention provides a process for obtaining solid cyanuric chloride from a cyanuric chloride vapor obtained by the trimerization of cyanogen chloride, wherein the cyanuric chloride vapor is introduced into the upper part of a separation chamber in the center of many individual cold inert gas streams, the solid cyanuric chloride, after emergence thereof from the separation chamber, is separated from the inert gas stream by the action of centrifugal and gravitational force and the inert gas, together with a residual content of very finely crystalline cyanuric chloride, is returned, after cooling thereof, as part streams to the separation chamber.
