    摘要： A method for preparing hydrazine and its compounds is described. Hypochlorous acid in a non-aqueous solvent is reacted with a carbonyl compound and with a nitrogen-contributing compound selected from the group consisting of ammonia, primary alkyl amines and mixtures of these. Hydrazine intermediates such as azines, hydrazones, and diazacyclopropanes are obtained and these may, if desired, be converted to hydrazine and its compounds, e.g., by hydrolysis.
