    • Abstract

       

      Chloramine, produced in the gas phase by the reaction of chlorine and ammonia, reacts with various primary and secondary amines in nonaqueous solvents in the presence of a fixed base to form the corresponding N-substituted hydrazines. The hydrazines synthesised include phenylhydrazine,p-tolylhydrazine, β-aminoethylhydrazine, N-aminopyrrolidine and N-aminopiperidine. Apparently, no hydrazine is formed when the reaction is carried out in the absence of fixed base. The effect of various factors, such as fixed base concentration, amine/chloramine ratio etc., on the overall yield of hydrazines has been studied. In this context, a modified chloramine gas generator giving improved yields is described. The optimum yield of chloramine is shown to be dependent upon the ratio of chlorine, ammonia and nitrogen taken, but is virtually independent of the reactor temperature.
