  • Patent number: 4250308
    Abstract: Solid cyanuric chloride is recovered by a process of spraying liquid cyanuric chloride which preferably is freed from chlorine and cyanogen chloride to the maximum extent possible, the cyanuric chloride is sprayed with the aid of known spraying apparatus into a separation container and solidified by indirect cooling.
    Type: Grant
    Filed: September 24, 1979
    Date of Patent: February 10, 1981
    Assignee: Deutsche Gold- und Silber-Scheideanstalt vormals Roessler

  • Patent number: 4245092
    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 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.
    Type: Grant
    Filed: September 25, 1979

    Inventors: Ralf Goedecke, Martin Liebert, Wolfgang Nischk, Wolfgang Plotz, Kurt Puschner
  • Patent number: 4245091
    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.

  • Patent number: 4245090
    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 at will 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.
