PROCESS FOR PRODUCING CYANURIC CHLORIDE (III)

摘要

The present invention provides a process for producing cyanuric chloride in a solid or liquid form from the reaction mixture obtained after the trimerization of cyanogen chloride, in which the reaction gas mixture is injected into a combined apparatus comprising essentially a separating column and a condenser, said reaction gas mixture being injected in said apparatus, the bottom of the separating column is kept at the boiling temperature of the cyanuric chloride, whereupon the cyanuric chloride contained in the reaction gas mixture is cooled at the outlet of the condenser in the temperature range from 146 to 190.degree.C and in order to obtain the cyanuric chloride in the liquid form, the liquid cyanuric chloride is drawn off as such at the lower end of the separating column and/or fed directly, or after intermediate storage, to a spray tower and sprayed therein, whereupon the solid, fine-grained cyanuric chloride is removed at the bottom of the spray tower.
