Abstract
The invention relates to a process for the production of cyanuric chloride moldings, particularly in rod or flake form. Cyanuric chloride melt is cooled in a pressure cell equipped with a die capable of strand formation, wherein solidification takes place in the channel or channels of the die. The solidified cyanuric chloride is pressed out of the die in strand form at a temperature of 140.degree. C. or less, preferably 40 to 60.degree. C., and reduced in size as required. The process reduces the sublimation which is otherwise conventional during solidification and cooling.
