Uses and applications
What the substance is used for, by industry and function
Reaction of NCl3 with olefins gives high yields of vicinal dichlorides via a radical mechanism. When catalyzed with AlCl3, trichloramine acts as an aminating agent towards various organic substrates.
Flour bleach (no longer permitted in US).
Bleaching of flour, wastage control of citrus fruit.
How it is made
Trichloramine is prepared by reaction of (NH4)2SO4 with Cl2 or HOCl with ammonia in a 3:1 M ratio at pH 3-4.
Prepared by the action of chlorine gas or hypochlorous acid on ammonium salts ..., by reaction of anhydrous ammonia and anhydrous chlorine ..., industrially by electrolyzing an acidified solution of ammonium chloride: United States of America patent 2118903 (1938), Germany patent 641816 (1937), United Kingdom patent 494188 (1938)...
