Product Description

Maleic Anhydride is a white crystalline solid organic compound commonly used in the production of various chemicals and polymers. It is primarily manufactured by the oxidation of n-butane or benzene with air. Maleic Anhydride is a versatile intermediate chemical with applications in the synthesis of resins, coatings, adhesives, and plastics. It undergoes reactions with alcohols, amines, and other compounds to form maleate esters, which are used as monomers in the production of polyester resins, alkyd resins, and polyethylene terephthalate (PET) plastics. Maleic Anhydride is also employed in the manufacture of agricultural chemicals, pharmaceuticals, and surfactants. Additionally, it serves as a raw material in the production of fumaric acid, which finds application as a food additive and in the synthesis of resins and polymers. Maleic Anhydride is handled with care due to its irritant properties and potential health hazards associated with inhalation and skin contact. Proper safety precautions, including adequate ventilation and personal protective equipment, should be observed when working with this compound

Versatile Industrial Intermediate

Maleic Anhydride is essential in synthesizing a variety of high-demand industrial products, including unsaturated polyester resins, which are vital in the plastics and coatings industries. Its unique chemical structure makes it a valuable building block in pharmaceuticals and agricultural chemicals, driving innovation across sectors.

Safe Handling and Storage

Due to its corrosive properties and potential health risks, Maleic Anhydride must be handled with care. Always use protective equipment to avoid skin and eye contact. Store the product in airtight containers in a cool, dry, and well-ventilated area, away from strong bases and oxidizing agents, to maintain its stability and ensure a safe workplace.
