Abstract
Cyanuric chloride is prepared by passing hydrogen cyanide gas having a water content of less than 0.5% and chlorine gas through a bed of activated carbon catalyst at a raised temperature. The reaction is effected with a mol ratio Cl2:HCN 1.00 to 1.10, at 300-450 DEG C., and space velocity 40-120 hr. The product is condensed from the effluent and any cyanogen chloride in the product gas is recycled to the process. The gases are dried to less than 0.5% water content by calcium chloride, or silica gel. The activated carbon may be prepared by treating a carbonized organic substance at above 800 DEG C. with a stream of water vapour, carbon monoxide, or carbon dioxide, or by heating the substance with metallic chlorides, e.g. ZnCl2. The activated carbon should be dehydrated by heating at 700-1000 DEG C. under vacuum, e.g. less than 50 mm. Hg., or in an inert gas, e.g. CO2 or N2, cooled, and then saturated with cyanuric chloride at 200-300 DEG C. The resulting carbon catalyst of 3-10 mesh is filled into a tower.
