How does adiponitrile affect workers’ health?
Sep
We will learn about the potential hazards of exposure to Adiponitrile, including its effects on the respiratory system and skin, and how to protect ourselves from these dangers.
Additionally, the article will present protective measures and workplace safety when exposed to Adiponitrile. Understanding how to make the work environment safer and ensuring that workers are properly trained and equipped is extremely important.
1. What is Adiponitrile?
Adiponitrile is a chemical compound with the chemical formula C6H8N2. This compound is also called hexanedinitrile or 1,4-dicyanobutane. Adiponitrile is a type of nitrile, in which two cyano groups (-CN) are attached to consecutive carbon atoms in the carbon chain.
One of the main applications of adiponitrile is in the production of nylon-6,6, an important synthetic fiber in the textile industry. The production process of nylon-6,6 involves the reaction of adiponitrile and other chemical steps to create high-quality nylon fiber.

2. Where does Adiponitrile originate from in the production process?
Adiponitrile (or Adipic Dinitrile) is typically produced through a series of complex chemical reactions. This production process usually starts with a hydrocarbon source such as butadiene or cyclohexane. Here is an overview of the main production process of adiponitrile:
- Oxidation (Oxydehydrogenation): The process begins with the oxidation of the base hydrocarbon into a dinitrile (containing two cyano groups, -CN). This is often done through an oxydehydrogenation process, where hydrogen (-H) groups are removed and replaced by cyano groups.
- Hydrocyanation: Subsequently, this dinitrile (usually adiponitrile) can be produced by carrying out a hydrocyanation reaction, in which the cyanide ion (CN-) is added to another hydrocarbon. This reaction creates the cyano bonds in adiponitrile.
- Preparation and Separation: Finally, the adiponitrile product needs to be separated and purified from the reaction mixture and other by-products through separation and refining processes.
3. Industries containing Adiponitrile that pose hazards to workers
Adiponitrile is a chemical compound that can be hazardous to workers if not handled properly or when exposed to it in an unsafe work environment. Industries and applications containing adiponitrile that may pose hazards to workers include:
- Textile Industry: Adiponitrile is used to produce nylon-6,6, an important synthetic fiber in the textile industry. Workers in this industry may come into contact with adiponitrile during the production and processing of nylon fiber.
- Chemical Industry: Factories producing adiponitrile and other chemical products can create work environments with exposure to this substance. Workers in the chemical industry must implement safety measures when working with adiponitrile.
- Other Chemical Compound Manufacturing: Adiponitrile may also be used as a raw material or part of other production processes in the chemical industry.
- Research and Development: In laboratories and research facilities, adiponitrile may be used for research purposes and chemical product development. Workers in this field also need to adhere to safety measures.
To ensure worker safety, companies and organizations must strictly adhere to safety regulations regarding the handling, storage, and transportation of adiponitrile, as well as provide training and personal protective equipment for employees working in environments containing this compound.
4. How does Adiponitrile affect workers
Adiponitrile can affect workers in a potentially harmful and toxic way if not handled and used correctly. Here are some of the effects adiponitrile can have on worker health:
- Harmful effects via skin contact: Direct contact with adiponitrile can cause skin irritation, inflammation, and redness. Workers must use personal protection such as gloves and chemical-resistant clothing to ensure no direct skin contact.
- Harmful effects via inhalation: Adiponitrile vapor can irritate the respiratory tract and cause symptoms such as sore throat, coughing, difficulty breathing, and if exposure is high and prolonged, it can cause lung damage.
- Fire and explosion hazard: Adiponitrile can be flammable and explosive if it comes into contact with flames or other ignition sources. This requires special safety measures for storing and handling adiponitrile.
- Toxicological risk: Adiponitrile contains cyano groups (-CN) which can be toxic if exposure is long-term or at high concentrations. This is especially true during the production and processing of adiponitrile.
5. Permissible safe concentration of Adiponitrile for human exposure
The permissible safe concentration of adiponitrile for human exposure depends on the type of contact, duration of exposure, and various other factors. Specifically, safety information sources and regulations, such as the Threshold Limit Values (TLV) issued by the American Conference of Governmental Industrial Hygienists (ACGIH) and guidelines from regulatory agencies, can determine safe concentrations for specific situations.
At a basic level, if working in an industrial environment, adhering to safety standards and limiting exposure to adiponitrile is important. Organizations like the Occupational Safety and Health Administration (OSHA) in the United States provide guidelines and safety principles to protect workers from the negative impacts of chemical substances.
However, adiponitrile is a toxic substance and has the potential to harm human health. Therefore, safety measures should be implemented to limit exposure to it, and safety regulations and guidelines from authorities must be strictly followed. Ensuring no unnecessary contact with adiponitrile is the best way to ensure worker safety.
6. Measures to minimize the impact of Adiponitrile on worker health
To minimize the impact of Adiponitrile on worker health, a range of safety and risk management measures must be applied. Here are some important measures:
- Chemical industry occupational safety training: Provide comprehensive training to workers on the properties of adiponitrile, potential hazards, and safe work practices. Ensure they understand how to use personal protective equipment and safety rules.
- Use of personal protective equipment: Ensure workers use the correct type of personal protective equipment such as gloves, safety glasses, chemical-resistant clothing, masks, and respiratory protection if necessary.
- Control work processes: Optimize work processes to reduce exposure to adiponitrile. Use closed systems, exhaust ventilation, and emission control measures to prevent the substance from being released into the work air.
- Monitor the work environment: Conduct work environment monitoring to ensure that exposure levels to adiponitrile do not exceed established safety thresholds.
- Work in a comfortable environment: Ensure the work environment has a ventilation and air purification system to reduce the risk of inhaling adiponitrile vapors.
- Safe storage and handling: Store adiponitrile according to regulations and follow rules for the storage and disposal of chemical waste.
- Alternative products: If possible, use alternative or substitute products that do not contain adiponitrile.
- Medical consultation: Ensure that workers undergo regular health checks and related medical tests to monitor exposure to adiponitrile.
- Periodically organize occupational environment monitoring in factories and enterprises, collect and analyze factors harmful to workers, and from there, adjust to reduce hazard levels to prevent occupational diseases for them.
