Apparatus for producing cyanogen chloride by spray reaction means
Abstract
Abstract Apparatus for producing cyanogen chloride has a vaporizer in which hydrogen cyanide and chlorine are mixed to produce a gaseous mixture. A spray chamber is provided in which the gaseous mixture is dispersed, and means are provided for spraying water into the spray chamber, the amount of water being controlled so that the resulting hydrochloric acid is at a concentration of about 10 percent. If necessary to complete the reaction, a cooled reactor can be provided into which the cyanogen chloride, unreacted hydrogen cyanide vapor and chlorine are passed. The reactor should be partially flooded with hydrochloric acid at a concentration of about 10-20 percent and chlorine stripped from the hydrochloric acid produced in the spray chamber is also fed to the reaction column.
