Applications in Industry

Maleic Anhydride serves as a crucial raw material in the synthesis of unsaturated polyester resins, which are widely used in fiberglass-reinforced plastics, coatings, and adhesives. It also acts as an intermediate for plasticizers, agricultural chemicals, lubricating oil additives, and water treatment chemicals in industrial operations, ensuring high performance across various manufacturing sectors.

Safe Transport and Storage

Proper handling of Maleic Anhydride is essential due to its corrosive and toxic nature. The product is classified as UN 2215 (Class 8, Packing Group III) for transport and is typically supplied in 25 kg or 500 kg bags. To preserve quality and safety, it should be stored away from moisture and direct sunlight in a well-ventilated, cool, and dry area. Original packaging maintains its integrity for up to two years.

Key Physical and Chemical Properties

This compound is a white, free-flowing powder with a strong, acrid odor. Maleic Anhydride exhibits an acidic pH, a density of 1.48 g/cm, and a melting point of 52.8C. Its limited solubility in water, combined with high reactivity, makes it important for controlled processes. It hydrolyzes rapidly when exposed to moisture, forming maleic acid.

FAQs of Maleic Anhydride:

Q: How should Maleic Anhydride be safely handled and stored?

A: Handle Maleic Anhydride in a well-ventilated area, using protective gloves, clothing, and eye protection as it is corrosive and toxic. Store it in its original packaging in a cool, dry, well-ventilated space, away from moisture and sunlight, to preserve its stability and safety for up to two years.

Q: What are the primary industrial uses of Maleic Anhydride?

A: Maleic Anhydride is primarily used in the production of unsaturated polyester resins, coatings, plasticizers, agricultural chemicals, copolymers, and lubricating oil additives. It acts as a vital intermediate in the chemical industry, supporting the manufacturing of diverse materials and chemicals.

Q: When does Maleic Anhydride decompose or react, and what are the associated hazards?

A: Maleic Anhydride remains stable under normal conditions, but reacts rapidly with water to form maleic acid. Decomposition occurs when exposed to excessive heat, potentially releasing toxic fumes. Inhalation, ingestion, or direct contact can cause severe burns and respiratory irritation.

Q: Where is Maleic Anhydride typically applied or processed?

A: This compound is processed in chemical manufacturing plants, resin production facilities, and industries involved in producing coatings, paper, and water treatment chemicals. Its applications span industrial sectors where it is handled by trained personnel with appropriate safety equipment.

Q: What are the transport regulations for Maleic Anhydride?

A: Maleic Anhydride must be transported according to international regulations as a corrosive substance (UN 2215, Class 8, Packing Group III). It is usually shipped in 25 kg or 500 kg bags, with labeling and packaging requirements strictly followed to ensure safety during transit.

Q: How is Maleic Anhydride beneficial in manufacturing processes?

A: Due to its high reactivity and purity, Maleic Anhydride enables efficient production of high-performance resins, additives, and specialty chemicals. Its use contributes to enhanced product quality and process versatility across several industries, supporting modern material advancements.
