ABSTRACT:
There is provided a process for the recovery of cyanuric chloride in solid or liquid form from the reaction mixture which results from the trimerization of cyanogen chloride wherein to recover the cyanuric chloride in liquid or solid form the gaseous reaction mixture is introduced into an apparatus combination consisting essentially of a stripping column and a condenser connected at the outlet side, preferably a head condenser, preferably above the stripping column, and in which the sump of the stripping column is held to the boiling temperature of the cyanuric chloride whereupon the cyanuric chloride contained in the gaseous reaction mixture depending on the regulation of the temperature at the outlet of the condenser in the range of 146.degree. to 190.degree. C. is partially condensed, after which to recover the liquid cyanuric chloride in liquid form it is removed as such at the lower end of the stripping column while the residual gas leaving the condenser and still containing cyanuric chloride, which amount of cyanuric chloride is controlled by the temperature at the outlet of the condenser, is led to a separating chamber and the residual cyanuric chloride is recovered there by known process.
