The method posted below is the 100% OTC method used to produce hydrazine. Not only is it 100% OTC, but it can be done from one trip to the supermarket (locations may vary). Hydrazine is quite a useful chemical in many divisions of chemistry. Hydrazine derivatives are being tested as cancer recovery aides (basically cures, but it's debatable). In energetic chemistry, it can be used to make many different types of explosives, such as the Nickel-Hydrazine-Nitrate complex. It is typically prepared by reacting sodium hypochlorite with ammonia, but with a chelating agent. If you just mix ammonia and sodium hypochlorite, you'll just get nitrogen gas. However, with the chelating agent, they bond in the way neccesary for this reaction albeit with terrible yeilds. Always optimistic though - terrible is better than zero. Hydrazine can be found in a few different forms. There is anhydrous hydrazine, which is pure hydrazine. This is of course, very dangerous. Hydrazine hydrate, which is a liquid, is actually 64% hydrazine by weight. Since it's a hydrate, you can't simply distill of the hydrazine. Storing it as it's hydrate is much more storage friendly, and much safer. The last form is hydrazine sulfate. This is a white solid, which is not very soluble in cold water (but very soluble in hot). Since hydrazine hydrate is quite stable, safe (relatively) and storage friendly, it's the most common form to find it in. I will discuss the preparation of all three (once I have performed all three preparations).
