Maleic Anhydride
$1240.00
Maleic anhydride (C₄H₂O₃) is a colorless or white crystalline solid with a pungent odor. It is a highly reactive compound and is widely used in the chemical industry as an intermediate in the production of various resins, plastics, and chemicals. It is derived from the oxidation of benzene or butane and is an important feedstock for manufacturing several industrial chemicals.
Industrial Applications:
Production of Unsaturated Polyester Resins (UPR):
Maleic anhydride is a key raw material in the production of unsaturated polyester resins, which are used in the automotive, construction, and marine industries for applications such as fiberglass reinforcement, coatings, and composite materials.
Chemical Synthesis:
It serves as an intermediate in the production of various chemicals, including butanediol, tetrahydrofuran (THF), glutaric acid, and succinic acid.
Plasticizers:
Maleic anhydride is used in the production of plasticizers for PVC (polyvinyl chloride) to improve flexibility and durability in products like cables, flooring, and films.
Agricultural Chemicals:
It is employed in the manufacture of certain pesticides and herbicides, as well as in the production of additives for crop protection.
Coatings & Paints:
Maleic anhydride is utilized in the production of alkyd resins for coatings, paints, and varnishes, offering improved durability, adhesion, and gloss.
Food & Pharmaceuticals:
It is used in the synthesis of certain pharmaceuticals and food additives, such as maleic acid, which has applications as an acidulant.
Storage Recommendations:
Temperature: Store in a cool, dry place, away from heat and direct sunlight.
Packaging: Keep in tightly sealed, moisture-resistant containers to prevent hydrolysis, which can lead to the formation of maleic acid.
Shelf Life: Stable for up to 2 years when stored properly.
Safety Note:
Maleic anhydride is a strong irritant to the eyes, skin, and respiratory system. It can cause severe burns if it comes into contact with moisture or mucous membranes. Proper personal protective equipment (PPE) such as gloves, goggles, and a fume hood should be used when handling. Always follow safety guidelines and ensure proper ventilation in the storage and handling areas.
