Jain, SR and Chellappa, D (1985) Syntheses of some N-substituted hydrazines by the anhydrous chloramine process. In: Proceedings - Indian Academy of Sciences, Chemical Sciences, 95 (4). pp. 391-399.
ClNH2, produced in the gas phase by the reaction of Cl2 and NH3, reacts with various primary and secondary amines in nonaq. solvents in the presence of a fixed base to form the corresponding N-substituted hydrazines. The hydrazines synthesized include PhNHNH2 [100-63-0], p-tolylhydrazine [539-44-6], H2NCH2CH2NHNH2 [14478-61-6], N-aminopyrrolidine [16596-41-1], and N-aminopiperidine [2213-43-6]. 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 concn., amine/ClNH2 ratio etc., on the overall yield of hydrazines was studied. A modified ClNH2 gas generator giving improved yields is described. The optimum yield of ClNH2 is dependent upon the ratio of Cl2, NH3, and N2 taken, but is virtually independent of the reactor temp.
