What is another name for acetonitrile?
Cyanomethane
Acetonitrile is a colourless, highly flammable liquid. Other names for acetonitrile are methyl cyanide and cyanomethane.
Is ACN acetonitrile (CAS 75-05-8)?
Acetonitrile is physical properties manifest as a colorless, transparent liquid possessing a distinctive pungent odor. As a non-protonic solvent, acetonitrile exhibits exceptional solubility, dissolving various organic compounds, inorganic salts, and gaseous substances. It forms an infinitely miscible system with water, methanol, ethanol, and other alcohol-based solvents.
What is acetonitrile(ACN CAS 75-05-8) used for?
Acetonitrile (ACN CAS 75-05-8) is an organic compound with multiple common uses in chemical reactions:
- Synthetic Chemistry: ACN can be used to synthesize various organic compounds, such as amides, acid anhydrides, and esters. These compounds find extensive applications in pharmaceuticals, pesticides, dyes, and other fields.
- Polymer Material Preparation: ACN serves as a raw material for polymerization reactions to produce polymers like polyacrylonitrile. These polymer materials are widely used in textiles, plastics, rubber, and related industries.
- Solvent Applications: As an excellent organic solvent, acetonitrile dissolves numerous organic and inorganic substances, making it widely used in coatings, inks, electronics, and related industries.
- Preparation of Metal Compounds: Acetonitrile (ACN) reacts with metals to form organometallic compounds like copper acetonitrile. These metal compounds find extensive applications in catalysts, electronic materials, and other fields.
Acetonitrile (CAS 75-05-8)：Safety and Health Hazards
Small amounts of acetonitrile are relatively toxic, but in large doses, it can be converted into hydrogen cyanide, which is toxic. Since it takes time for the body to metabolize acetonitrile to cyanide, its toxic effects are delayed. The eyes, throat, lungs, and nose can become irritated.
Its long-term effects are thyroid enlargement, headaches, numbness, lack of appetite, dizziness, weakness, and tremors. Scientists observe animal reproductive problems, including birth defects and low birth weights. Acetonitrile can affect the liver, lungs, central nervous system, and kidneys for a long time.
Acetonitrile Storage
Acetonitrile Storage Guidelines
Acetonitrile should be stored in closed, tightly sealed containers, kept well away from heat, sparks, and open flames. Ensure the storage area is dry, well-ventilated, and clearly segregated from substances that may react with acetonitrile, including:
- Strong oxidizing agents
- Strong acids
- Reducing agents
- Bases
Storage containers should be regularly inspected for signs of leakage, corrosion, or physical damage to ensure long-term safety.
To further protect personnel and facilities, implement the following safety measures:
- Regularly review and update storage procedures as needed
- Clearly label all containers and designated storage areas
- Train all personnel who may access the storage area on proper handling and storage practices
- Maintain accurate records of storage locations and inventory quantities
Responding to Spills and Leaks
In the event of a spill or leak, evacuate the area immediately. As acetonitrile is highly flammable, eliminate all potential ignition sources to prevent fire or explosion.
Ensure adequate ventilation to reduce vapor accumulation and inhalation risk. Use inert, absorbent materials to contain the spill, and handle cleanup operations only with spark-proof tools.
