Abstract
The chlorination of methylamine by sodium hypochlorite in dilute aqueous medium (5.1< pH< 9) leads to the formation of N‐chlormethylamine and (or) N, N‐dichlor‐methylamine according to experimental conditions (dose of chlorine applied, time of reaction, pH). The concentration of total chlorine remains constant during reaction and in a period of 24 hours the chloramines obtained are pratically stable. At 20°C, the rate of disappearance of methylamine (r1) and the rate of formation of N, N‐dichloromethylamine (r2) are: r1 (M. min.‐1) = 4.4 x 109 (CH3NH2) (HClO) for a pH of 5.35 and 5.75, and r2 (M. min.‐1)= 17.3 x 103 (CH3NClH) (HClO) at 5.35 < pH < 8.7.Keywords
