Abstract: 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.

Abstract: Inventia se refera la un procedeu pentru manipularea clorurii de cianuril lichide prin introducerea clorurii de cianuril solide într-o topitura de clorura de cianuril. Procedeul consta în aceea ca, în scopul relizarii unui dop de produs etans, impermeabil la gaze, se introduce clorura de cianuril solida, la temperatura camerei în spatiul de vapori deasupra unei topituri de clorura de cianuril aflata la 170 degree C cu ajutorul unui transportor cu melc care nu mai are elemente elicoidale pe ultima portiune, înainte de intrarea în spatiul de vapori si care poate fi prevazut la capat cu o clapeta încarcata cu o greutate.

Abstract: 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.
