Abstract
In the manufacture of nitrogen trichloride in a gaseous form suitable for bleaching flour by bringing together in solution chlorine and an ammonium compound as described in the parent Specification and removing the nitrogen trichloride in a stream of an inert gas, the solution is allowed to stand before the nitrogen trichloride is removed, in order to enable the reaction to be completed. In one example, a solution of an ammonium salt or of ammonium hydroxide is mixed with a solution of chlorine and after standing for at least a minute the nitrogen trichloride is removed by passing air over or through the solution. In other examples an ammonium salt or ammonium hydroxide is dissolved in a solution of chlorine, or chlorine is dissolved in a solution of the ammonium compound and the nitrogen trichloride removed by a current of air after the necessary time interval has elapsed. The nitrogen trichloride may also be removed by passing air up a tower packed with inert material down which the solution is caused to flow. Or, the solution containing the nitrogen trichloride after being allowed to stand may be sprayed into a stream of air.
