Dykhanov, N. N.; Ryzhkova, T. S.; Khaletskii, A. M. published an article in 1967, the title of the article was Ammonolysis of isomeric chlorobenzensulfonamides.Application of 97-09-6 And the article contains the following content:
Heating o-ClC6H4SO2NH2 (I) with 15 moles NH3 (as 30% solution in water) to 200° in the absence of catalysts failed to give any reaction. However, in the presence of Cu2O, ammonolysis took place at 145-50° to give 5-6% o-H2NC6H4SO2NH2 (II) and a polymeric mass (III). Hydrolysis of III with 40% H2SO4 gave o-H2NC6H4SO3H and II. Presence of an alkyl substituent on the amino group of I prevents the formation of a polymer. Thus, ammonolysis of o-ClC6H4SO2NHMe in the presence of Cu+ at 155-60° gave ∼80% o-H2NC6H4SO2NHMe. Also ammonolysis of m-ClC6H4SO2NH2 gave ∼80% m-H2NC6H4SO2NH2 and no polymer. Formation of II was explained by postulating the existence of an intermediate Cu+ complex of the average composition [ClC6H4SO2NH2.CuCl.2H2O],which at 200° nearly instantaneously decompose to III. The experimental process involved the reaction of 3-Nitro-4-chlorobenzenesulfonamide(cas: 97-09-6).Application of 97-09-6
3-Nitro-4-chlorobenzenesulfonamide(cas:97-09-6) belongs to amides. Amides are pervasive in nature and technology. Proteins and important plastics like Nylons, Aramid, Twaron, and Kevlar are polymers whose units are connected by amide groups (polyamides); these linkages are easily formed, confer structural rigidity, and resist hydrolysis.
