摘要： Solid cyanuric chloride is supplied to the gas space of a cyanuric chloride melt with the help of a gas tight product stopper. Preferably there is used for this a screw conveyor in which the gas tight stopper is formed at the end of the screw conveyor; it is most favorable if the helix ends before the last section of the tube of the screw conveyor.

摘要： To obtain a cyanogen chloride which is practically free from water and preferably also free from hydrogen cyanide, hydrogen chloride and organic compounds, the crude cyanogen chloride is fractionally distilled. The return is led in countercurrent flow to the crude gas, thereby takes up the impurities and is further evaporated in the lower portion of the column, respectively in a special apparatus, by a liquid whose temperature is higher than the boiling temperature of cyanogen chloride. Thereby this liquid also takes up the impurities. The purification action is aided by a wash for the crude cyanogen chloride connected in series before it enters the fractionating column. It is very advantageous to combine the process with a plant for the production of cyanogen chloride.
摘要翻译：为了获得实际上不含水的氰氯化物，优选也不含氰化氢，氯化氢和有机化合物，分馏了粗氯化氰。回流以逆流流向粗气体，从而占据杂质，并在专用设备中通过温度高于氯化氰沸点的液体分别在塔的下部蒸发。因此，这种液体也会占据杂质。纯化作用通过在进入分馏塔之前串联连接的氯化氰原料的洗涤来辅助。将该方法与用于生产氯化氰的设备相结合是非常有利的。

摘要： 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 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 at the outlet of the condenser is cooled in the range of 146.degree. to 190.degree. C. and to recover the liquid cyanuric chloride in liquid form it is removed as such at the lower end of the stripping column and is either directly or, in a given case, after an intermediate storage led to a spray tower and is sprayed whereupon the solid, fine-grained cyanuric chloride is withdrawn at the bottom of the spray.
