Abstract

Trichloramine reacts with excess NH, and base (B) with the rate expression-d [NC13]/dt= 2kB [B][NH3][NCI,], based on the overall stoichiometry 2NClJ+ 3NH3+ 30H--3NH2CI+ N2+ 3CI-+ 3H20. The reaction is general-base assisted with kB values (M-2 sl, 25.0 OC, p= 0.50 M) of 4.46 X IO3 for OH-, 3.3 X IO3 for PO:-, and 22 for NH,. A water path with kHlo= 2.2 M-'sI and an acidic phosphate path for H2PO<(kHB= 450 M-2 SI) are also found. The rate- ...
