Chemical Properties
(1)
Strong alkaline liquid
Makes hydrazine salts from inorganic/ organic acids.
(2)
Strong reductive activity
Reduces metal ions to metallic state.
Rapidly reacts with oxidizers. (might explosively react in high concentration.)
(3)
Quickly decomposes in contact with heavy metals and their oxides. (IronⅡoxide, copperⅡoxide, etc.)
(4)
Easily decomposes in contact with platinum black and Raney nickel.
(5)
Reacts with aldehydes, ketones and generates azine, hydrazone.
