Polymers and Copolymers: Maleic anhydride is also utilized to produce various polymers and copolymers, including polyethylene and polypropylene graft copolymers, which enhance the properties of these materials.

2. Chemical Intermediates

In Turkey, maleic anhydride serves as an important chemical intermediate in the production of various compounds, such as:

Maleic Acid: By hydrolyzing maleic anhydride, maleic acid is produced, which has applications in industries such as food, pharmaceuticals, and agriculture.

Fumaric Acid: Through a catalytic process, maleic anhydride can be converted to fumaric acid, which is used as an acidulant in the food and beverage industry.

Butanediol: It is a precursor for the synthesis of 1,4-butanediol, which is used in the production of plastics, polyurethanes, and other industrial applications.

3. Paper Industry

Maleic anhydride is employed in the paper industry in Turkey as a sizing agent. It improves the paper's resistance to water and oil, enhancing its printability and quality.

4. Textile Industry

In Turkey's textile sector, maleic anhydride is utilized as a dye-fixing agent and as a cross-linking agent for textile finishes, improving fabric durability and color fastness.

5. Agriculture

Maleic anhydride derivatives, such as maleic hydrazide, have applications in agriculture as growth regulators and herbicides, helping Turkish farmers manage crop yields effectively.

6. Adhesives and Sealants

The chemical's adhesive properties make it an essential ingredient in adhesive formulations, used in various industries, including construction, automotive, and packaging.

7. Oil and Gas Industry

Maleic anhydride is used in the oil and gas industry in Turkey to control corrosion and scale formation in pipelines and production facilities.

Maleic anhydride plays a vital role in Turkey's industrial landscape. Its diverse applications in polymers, chemicals, textiles, agriculture, and other sectors contribute significantly to the country's economic development and the quality of products produced. As technology advances and industries evolve, the importance of maleic anhydride in Turkey is expected to continue to grow.

Maleic anhydride in China

The main raw material for the production of maleic anhydride is benzene. From the perspective of export destinations, my country's maleic anhydride is mainly exported to India and Turkey, accounting for 27.1% and 25.5% respectively in Turkey.

At present, the main production methods of maleic anhydride in China are benzene oxidation and n-butane oxidation. Among them, the production capacity of n-butane method accounted for 77%,the production capacity of benzene oxidation method accounts for only 23% in Turkey.

Storage and Handling

The storage and handling of maleic anhydride, like many chemicals, require careful attention to safety and environmental considerations. Maleic anhydride is a white, crystalline compound that is highly reactive and can pose health and safety risks if not handled properly. Here are some guidelines for the storage and handling of maleic anhydride:


Container: Maleic anhydride is typically stored in containers made of materials like stainless steel, glass, or lined drums. These containers should be tightly sealed to prevent moisture from entering.

Location: Store maleic anhydride in a cool, dry, and well-ventilated area away from sources of heat, open flames, sparks, and direct sunlight. Ensure that the storage area is well-marked and designated for hazardous materials.

Temperature: Keep the storage temperature below the material's melting point (52-53°C or 126-127°F) to prevent it from melting and forming lumps or becoming more reactive.

Separation: Store maleic anhydride away from incompatible substances, such as strong oxidizers, reducing agents, and strong bases. Segregate it properly to avoid chemical reactions.

Moisture Control: Maleic anhydride is sensitive to moisture, and exposure to water can cause it to hydrolyze, forming maleic acid. Use desiccants or moisture-absorbing materials in the storage area to maintain low humidity levels.

Labeling: Clearly label all containers with the chemical name, hazard warnings, and safety information.


Personal Protective Equipment (PPE): When handling maleic anhydride, wear appropriate personal protective equipment, including safety goggles, chemical-resistant gloves, a lab coat, and respiratory protection if necessary.

Ventilation: Work in a well-ventilated area or use local exhaust ventilation systems to control exposure to vapors. Avoid inhaling the fumes.

Avoid Skin Contact: Avoid skin contact with maleic anhydride, as it can cause irritation or burns. In case of skin contact, immediately wash the affected area with plenty of water and seek medical attention if necessary.

Eye Protection: Wear safety goggles to protect your eyes from splashes. In case of eye contact, rinse your eyes thoroughly with water for at least 15 minutes and seek medical attention.

Avoid Ingestion: Do not ingest maleic anhydride. Wash hands thoroughly before eating, drinking, or smoking after handling the chemical.

Spill Response: In the event of a spill, follow established spill response procedures, including containing the spill, absorbing the material with inert absorbents, and disposing of the waste properly.

Fire Safety: Maleic anhydride is combustible. Keep it away from open flames and ignition sources. Use appropriate fire extinguishing agents, such as dry chemical or carbon dioxide, if a fire occurs.

Emergency Measures: Familiarize yourself with emergency response procedures and have access to safety equipment, eyewash stations, and emergency showers in the handling area.

Training: Ensure that personnel handling maleic anhydride are trained in its safe handling, storage, and emergency procedures.

Documentation: Keep detailed records of the quantity, storage, handling, and disposal of maleic anhydride as required by regulations.

Always consult the Material Safety Data Sheet (MSDS) or Safety Data Sheet (SDS) provided by the manufacturer for specific information on the safe storage and handling of maleic anhydride, and comply with all applicable safety regulations and guidelines.
