Abstract

The present invention provides a process for obtaining solid cyanuric chloride from the cyanuric chloride vapor obtained by trimerizing cyanogen chloride by separating out in a separation chamber, wherein cyanuric chloride vapor and cold air are introduced into the separation chamber through obliquely upwardly directed inlets in such a manner that an intensive mixing up of the cyanuric chloride vapor with the cold air takes place after emergence from the inlet pipes, the cyanuric chloride-free waste gases are withdrawn from the upper part of the separation chamber and the solid cyanuric chloride is removed from the lower part of the separation chamber.
