| titleOfInvention | Process for production of cyanuric chloride |
| abstract | There is provided a process for the recovery of liquid cyanuric chloride from a mixture formed by the trimerization of cyanogen chloride in a trimerization reactor with subsequent fractionation of said mixture comprising conducting the mixture in an at least partially gaseous condition at 146* to 500*C. to a column system, bringing said mixture in a first fractionating column into contact with a solvent for cyanuric chloride having a boiling point between that of cyanogen chloride and that of cyanuric chloride and which is stable to cyanuric chloride, cyanogen chloride, chlorine and hydrogen chloride, recovering condensed liquid cyanuric chloride from the bottom of said first column at a temperature above the boiling point of said solvent, removing the distillate mixture containing solvent, cyanogen chloride, chlorine and any carbon dioxide, nitrogen and hydrogen chloride from the top of said first column, partially condensing a portion of said distillate and returning said partial condensate to the top of the first fractionating column, leading the solvent containing residual gas of chlorine, cyanogen chloride and any carbon dioxide, nitrogen and hydrogen chloride present to a second fractionating column adding sufficient liquid cyanogen chloride to the top of said second column to maintain a reflux in the top of said second column, removing a mixture of chlorine and cyanogen chloride and any carbon dioxide, nitrogen and hydrogen chloride free of said solvent from the top of said second column, returning the chlorine and cyanogen chloride to the trimerization reactor, insuring that the gas entering said reactor contains at least 50 weight percent cyanogen, collecting chlorine and cyanogen chloride free solvent in the bottom of the second column and returning it to the top of the first fractionating column. |
