Hydrazine hydrate is also known as hydrated hydrazine. Pure product is a colorless and transparent oily liquid with a light ammonia smell, smoke in humid air, strong alkalinity and hygroscopicity. Under normal pressure, helium can form azeotrope with water. Industrially, a 40%-80% aqueous solution of hydrazine hydrate or a salt of hydrazine is generally used. Hydrazine hydrate liquid exists in the form of dimer, miscible with water and ethanol, insoluble in ether and chloroform; it can erode glass, rubber, leather, cork, etc., and decomposes into N2, NH3 and H2 at high temperature; hydrazine hydrate reduction Extremely strong, reacts violently with halogen, HNO3, KMnO4, etc., and absorbs CO2 in the air to produce smoke. Hydrazine hydrate and its derivatives are widely used in many industrial applications as reducing agents and antioxidants for the preparation of pharmaceuticals, foaming agents, and the like.
Avoid contact with oxides, oxygen, metal powder, organic materials, the staff should be fully protected, skin and eye contact, should be washed directly with plenty of water, and ask the doctor to check the treatment. The work area must be adequately ventilated and often used with appropriate equipment to detect radon concentrations in the production area. It can be mixed with water and alcohol, and is insoluble in chloroform and ether. It has strong basicity and reducibility and is a strong reducing agent. In contact with the oxidant, it will spontaneously ignite. It is highly corrosive and permeable. It absorbs carbon dioxide in the air. poisonous. The refractive power is very strong. It is quite difficult to flow in the air, and it has a specific smell unlike ammonia. It is miscible with water and alcohol and cannot be miscible with ether or chloroform.
