ABSTRACT:
The present invention provides a process for obtaining cyanuric chloride in solid and/or liquid form from an optionally contaminated cyanuric chloride vapor, wherein cyanuric chloride, after dilution with an air stream with a temperature of from 60.degree. to 140.degree. C., is introduced into the lower part of a separation chamber cooled to a temperature of from 20.degree. to 50.degree. C., the separated solid cyanuric chloride is optionally converted into liquid form in a melt container at a temperature above 146.degree. C. and the cyanuric chloride vapor, after again diluting with hot air with a temperature of from 50.degree. to 140.degree. C., returned from the melt container into the separation chamber, whereas the cyanuric chloride-free waste gases are withdrawn above the desublimation zone of the separation chamber.
