Abstract

Solid cyanuric chloride is recovered by a process of spraying in the presence of a cooling medium liquid cyanuric chloride which preferably is freed from chlorine and cyanogen chloride, the cyanuric chloride is sprayed with the aid of known spraying apparatus into a separation container optionally with a propellant, while simultaneously with the cyanuric chloride spraying a liquid cooling medium through a second spraying apparatus separate from the first spraying apparatus, withdrawing the solidified cyanuric chloride from the separatory container and drawing off the resulting now gaseous cooling medium containing cyanuric chloride from the lower portion of the separatory container.
