摘要： Finely divided solid cyanuric chloride is produced by feeding a jet of liquid cyanuric chloride into a separatory container, cooling the liquid cyanuric chloride with recycling inert gases to such an extent that the cyanuric chloride is separated in crystalline form, washing the thereby warmed cyanuric chloride vapor or dust containing gases free of cyanuric chloride in countercurrent flow with an inert liquid that is a good solvent for cyanuric chloride in a washing column connected to the outlet side of the separatory column, thus simultaneously cooling the gases, and subsequently again returning the gases to the separatory container, while the temperature of the cyanuric chloride containing washing liquid which has increased in the washing process is again brought to the original temperature by leading it in the cycle over a heat exchanger and spraying the inside of the pipe connected to the separatory container and leading to the washing column constantly with the washing liquid while dividing a partial stream of the cyanuric chloride containing washing liquid in a distillation column into pure liquid cyanuric chloride which is recycled into the separatory column and into pure washing liquid which is recycled into the washing column.
