Participants

Reaction Steps

15.3 parts of 1-phenyl-4-amino-6-chloropyridazinium perchlorate is dissolved in 200 parts of water at 80° to 90°C; 5 parts of hydrazine hydrate is added and the whole is boiled for 3 hours. The reaction solution is concentrated to about half its volume and cooled. 13 parts (81.3% of theory, as hydrate) of 1-phenyl-4-amino-6-hydrazinopyridazinium perchlorate is obtained; C10H12O4N5Cl.H2O, obtained with 1 mole of water of crystallization when recrystallized from water. Melting point 63° to 65°C.
