What is maleic anhydride?

Maleic anhydride (MA), or Toxilic anhydride, is an acid anhydride of maleic acid, a colorless or white solid with a sour taste at room temperature, and the molecular formula is C4H2O3.

Maleic anhydride belongs to the colorless needle-like or flaky crystals of the orthorhombic crystal system. Dissolve in water to generate maleic acid. Soluble in ethanol and form ester

Maleic anhydride is an important organic chemical raw material, mainly used in the synthesis of unsaturated polyester resins, coatings, medicines, pesticides, lubricant additives, food additives, etc.

Note: it can explode when mixed with air

Uses of maleic anhydride:

  1. It can be used as a raw material for the production of 1,4-butanediol, γ-butyrolactone, tetrahydrofuran, succinic acid, unsaturated polyester resin, alkyd resin, etc., and also used in medicine and pesticides
  2. Maleic anhydride, also known as maleic anhydride, maleic anhydride, and anhydrous malic anhydride, is an important basic raw material for unsaturated organic acid anhydrides.
  3. Used in pesticide production to synthesize organophosphorus insecticide malathion intermediate diethyl maleate, pyridazinphos intermediate 1-phenyl-3,6-dihydroxypyridazine, and Intermediate of pyrethroid insecticide tetramethrin, fungicide, captan.
  4. Raw materials for the production of unsaturated polyester resins, alkyd resins, pesticide malathion, 4049 high-efficiency and low-toxic pesticides, and long-acting iodosamine.
  5. It is also paint, maleic rosin, polymaleic anhydride, maleic anhydride-styrene copolymer.
  6. It is also an organic chemical raw material for the production of ink additives, paper additives, plasticizers and tartaric acid, fumaric acid, tetrahydrofuran, etc.

Emergency treatment:

  1. Leak First Aid
    Isolate the leaked and contaminated area, install warning signs around it, and suggest emergency responders wear a respirator and chemical protective clothing. Avoid direct contact with spillage, use a clean shovel to collect it in a dry, clean covered container and transport it to the waste disposal site. In case of large leaks, collect and recycle or dispose of in a non-hazardous manner.

  2. protective measures
    Respiratory protection: A respirator must be worn if airborne concentrations exceed the norm.
    Eye Protection: Wear safety glasses.
    Protective Clothing: Wear work clothes (made of corrosion-resistant material).
    Hand protection: Wear rubber gloves.
    Other: I shower and change clothes after work. Pay attention to personal hygiene.

  3. first aid
    After skin contact: Remove contaminated clothing and rinse immediately with water for at least 15 minutes. In case of burns, see a doctor.
    After eye contact: Immediately lift eyelids and rinse with running water or saline for at least 15 minutes. Seek medical attention.
    Inhalation: Leave the site immediately with fresh air. Do not obstruct the airway. If necessary, give artificial respiration. Seek medical attention.
    Ingestion: If accidentally taken, rinse mouth immediately and drink milk or egg white. Seek medical attention.
    Extinguishing Methods: Water mist, foam, carbon dioxide, sandy soil.
    It can be used to produce various compatibilizers and strengthening agents by grafting maleic anhydride.

Storage:

  1. Precautions for transportation: The packaging must be complete and the loading must be secure. Do not allow containers to leak, collapse, fall or damage during transport. Mixed transportation and transportation of oxidizing agents, reducing agents, acids, edible chemicals, etc. is strictly prohibited. Avoid exposure to sun, rain and high temperatures during transportation.
  2. Storage Precautions: Store in a cool, dry and well-ventilated warehouse. Keep away from fire and heat sources. Keep container tightly closed. Store separately from oxidizing agents, reducing agents, acids and edible chemicals and avoid mixed storage. We have the right type and quantity of firefighting equipment. Storage areas must be equipped with suitable materials to prevent leakage.
  3. Packaging notes: plastic bag with full or middle open steel drum or two-layer kraft paper bag, fibreboard drum, plywood drum, plastic bag with cardboard drum or two-layer kraft paper bag, plastic drum with plastic bag ( solid) ; Plastic barrel (liquid).
