Physical and Chemical Properties

Adiponitrile has a simple chemical formula of NC(CH2)4(CN) and a molecular weight of 108.14 g/mol. It is soluble in water and common organic solvents like ethanol and acetone.

It can also react with acids, bases, and oxidizing agents, which make it highly reactive.

Production

Adiponitrile is produced via electrohydrodimerization of acrylonitrile and butadiene. This reaction takes place in the presence of catalysts or electrifying agents that help convert the monomers into adiponitrile.

The process is carried out in a reactor under specific temperature and pressure conditions.

Uses

Adiponitrile is extensively used in the production of nylon 6,6, which is used to make various synthetic fibers, including carpets, clothing, and tire cords. Nylon 6,6 is formed by the reaction of adiponitrile with hexamethylene diamine.

The resulting polymer is a high-strength, thermally stable material that can be easily molded into different shapes. Apart from its use in synthetic fibers, adiponitrile is also used in the manufacture of specialty chemicals, insecticides, and resins.

It is also used in the production of certain pharmaceutical intermediates.

Formula and Synonyms

Adiponitrile is also known as 1,4-Dicyanobutane, Hexanedinitrile, or Tetramethylene dicyanide. Its chemical formula is NC(CH2)4(CN), which indicates that it contains two carbon atoms, two nitrogen atoms, and six hydrogen atoms.

In conclusion, adiponitrile is a crucial component in the manufacturing of synthetic fibers, and its production and properties play a vital role in the textile industry. It is a versatile chemical compound with various uses in different industries.

Its chemical properties make it highly reactive and ideal for use in the synthesis of polymers and specialty chemicals. However, proper handling and precautions should be taken while handling adiponitrile due to its highly flammable nature.

Adiponitrile MSDS: A Comprehensive Guide to Handling and Safety Precautions

Adiponitrile (ADN) is a highly useful chemical compound in the manufacturing of synthetic fibers, but it is also highly flammable and reactive, which makes it pose certain risks during handling. This article will expand on the safety precautions for handling and storage of ADN as detailed in the Material Safety Data Sheet (MSDS) by delving deeper into the different sections of the MSDS.

Fire Fighting

ADN is highly flammable, which means it could ignite or explode if exposed to heat, sparks, or flames. In case of a fire, AFN should not be extinguished by using water.

Instead, a dry chemical powder, carbon dioxide or foam should be used. It is also advisable to take steps to prevent the buildup of hydrogen gas, which may result in an explosion.

Health Hazards

ADN poses various health hazards, including cyanosis, respiratory tract irritation, anoxia, weakness, dizziness, confusion, heart irregularities, coma, and even death. Chronic exposure may lead to liver and kidney damage.

The symptoms of ADN exposure depend on the severity of contact, which may range from mild irritation to severe symptoms. It is crucial to be aware of the symptoms of exposure and seek medical attention immediately if they occur.

First Aid

  1. In case of eye contact, flush eyes thoroughly with water for 15 minutes, lifting the upper and lower eyelids occasionally. Seek medical attention immediately.
  2. In case of skin contact, wash the affected area with soap and water for 15 minutes. If clothing is contaminated, remove it immediately and wash skin thoroughly before applying clean clothing.
  3. If the individual is not breathing, perform artificial respiration. Seek medical attention immediately.

Handling Precautions

Due to its highly reactive and flammable nature, it is imperative that ADN is handled with extreme caution. All employees should undergo proper training and wear appropriate protective gear such as gloves, goggles, and a respirator.

Proper hand washing should also be enforced after handling ADN. Inhalation of ADN should be avoided by providing proper ventilation in the work area.

Safety Facilities

It is essential to have safety facilities such as eyewash stations and safety showers in the work area in case of exposure. The work area should also have adequate ventilation to minimize the risk of inhalation or explosion.

In case of spills or leaks, proper disposal protocols should be in place.

Conclusion

Adiponitrile is a vital component for the manufacturing of synthetic fibers, but its highly reactive and flammable nature could pose significant safety risks if not handled properly. Proper handling and adherence to safety precautions are essential to prevent potential contamination and accidents.

The MSDS serves as a critical resource for understanding the hazards associated with ADN’s handling and storage. Companies that deal with ADN should ensure that they are well-versed in the MSDS guidelines as part of their safety protocols.
