Product Description Product DescriptionMaleic anhydride, also known as maleic anhydride, is an important organic chemical raw material with a wide range of industrial applications. The following provides a detailed introduction to its basic information, properties, production methods, and applications:I. Basic InformationChemical Name: Maleic AnhydrideEnglish Name: Maleic AnhydrideMolecular Formula: C4H2O3Molecular Weight: 98.06CAS Number: 108-31-6Customs Code: 2917140000II. Physical and Chemical PropertiesPhysical PropertiesAppearance: White crystalline powder or flaky solid at room temperature with a strong pungent odor.Melting Point: 52.8°C, Boiling Point: 202°C. Sublimes readily (sublimes when heated above 150°C).Solubility: Easily soluble in organic solvents (such as acetone, ether). Reacts rapidly with water to form maleic acid.Chemical PropertiesIt exhibits the typical reactivity of an acid anhydride and can undergo addition or substitution reactions with water, alcohols, amines, and other substances to produce the corresponding carboxylic acids, esters, or amides.The molecule contains conjugated double bonds, making it susceptible to polymerization. It can also participate in the Diels-Alder reaction (diene addition reaction), making it an important intermediate in the synthesis of complex organic compounds.It is somewhat corrosive and irritating, potentially irritating to the skin, eyes, and respiratory tract. Therefore, proper protection is required during contact.III. Production MethodsThere are two main methods for the industrial production of maleic anhydride:Benzene oxidation: Maleic anhydride is produced by air oxidation of benzene in the presence of catalysts such as vanadium-molybdenum. This is a traditional production process with mature technology but high raw material costs.N-Butane oxidation: Maleic anhydride is produced by air oxidation of petrochemical product n-butane in the presence of a vanadium-phosphorus oxide catalyst. This method, with its low-cost raw materials and environmental friendliness, has become the mainstream production process. IV. Major ApplicationsMaleic anhydride is an important chemical intermediate, widely used in the following industries:Plastics Industry: Used in the production of unsaturated polyester resin (UPR), a key raw material for fiberglass, artificial marble, and coatings.Pharmaceuticals and Pesticides: Used as an intermediate in the synthesis of antibiotics, fungicides, and herbicides, such as chlorpheniramine maleate (an antiallergic drug).Coatings and Adhesives: Used in the preparation of alkyd resins and modified resins to improve the weather resistance and adhesion of coatings; it can also be used in the production of high-performance adhesives.Textiles and Papermaking: Used as a fabric treatment agent and paper sizing agent, improving fiber flexibility and paper strength.Other Industries: Used in the synthesis of lubricant additives, food additives (such as acidulants), and surfactants.
