1-Naphthylhydrazine hydrochloride Use and Manufacturing

Methods of Manufacturing

2.1 Synthesis of 2-naphthylhydrazine hydrochlorideNaN0alpha-Tetralone (14.6 g, 100 mmol) and 1-naphthylhydrazinium chloride (19.5 g, 100 mmol) were put in ethanol together with 2-3 drops of acetic acid, followed by boiling and stirring. After boiling for 3 hours, water was added and the resulting solid was filtered and dried to give a brown solid (24 g, 85%).
