β-Methoxyethylhydrazine - Introduction
Hydrazine, chemical formula for N2H4, is a colorless, pungent odor liquid. The following is a detailed description of the nature, use, preparation and safety information of hydrazine:
Nature:
1. The density of hydrazine is about 1.01 g/mL, the boiling point is 113-114 degrees Celsius, and the ignition point is 79 degrees Celsius.
2. Hydrazine is a strong reducing agent that can react with oxygen to produce water and nitrogen.
3. Hydrazine is soluble in water and most organic solvents, and many metal ions form salts.
4. Hydrazine is easy to absorb moisture in the air and reacts with oxygen in the air to form hydrazine salt.
Use:
1. Hydrazine is widely used in the chemical industry as a reducing agent and oxidant. It is commonly used in the fields of pesticides, dyes and pharmaceuticals.
2. Hydrazine is used as a hydrogen source in fuel cells to generate electrical energy.
3. Hydrazine can be used as a photosensitizer for photography and optical materials.
Method:
There are many methods for the preparation of hydrazine, the most commonly used method is the reaction of sodium nitrite and cobalt catalyzed ammonia.
1. First, sodium nitrite is mixed with ammonia to prepare nitrosamine.
2. Next, a nitrosoamine is reacted with a precursor compound of hydrazine to obtain a final hydrazine product.
Safety Information:
1. Hydrazine is irritating, contact with skin and eyes should be immediately rinsed with plenty of water, and medical treatment.
2. The steam of hydrazine is toxic, and excessive inhalation can cause dizziness, dyspnea and other uncomfortable symptoms. It should be away from the steam area of hydrazine and take appropriate protective measures.
3. Hydrazine is a flammable liquid, avoid contact with fire, storage should be away from high temperature or open flame.
4. In the operation of hydrazine, should wear protective gloves, goggles and protective clothing, avoid contact with the skin and inhalation of steam.
