Abstract
1423801 N-Halo amines NATIONAL PATENT DEVELOPMENT CORP 12 June 1973 [26 Oct 1972 (2)] 27911/73 Heading C2C [Also in Divisions C1 and C3] An N-haloamine is prepared by reacting in aqueous solution a second N-haloamine with an N-halo-free amine corresponding to the desired product, the second N-haloamine having a greater stability in aqueous solution than the desired N-haloamine, the halogen being Cl, Br or I. The reaction is preferably conducted at pH 8-12, particularly pH 10À5-11À5. The N-haloamines are preferably N-halosulphamic acids or organic N-haloamines of 2-11 C atoms exclusive of any N-acyl or N-aminoacyl group which group has 1-18 C atoms, particularly N-haloamines bearing a hydroxy, sulphonic acid, carboxylic acid, N-acyl or N- aminoacyl group and the free amine is preferably an amine bearing a hydroxy, sulphonic acid, carboxylic acid, N-acyl or N-aminoacyl group. In an example N-chloro-glycine is obtained from glycine and N-chlorotaurine.
