Factory Supply of Maleic Anhydride with Wholesale Price/Ma

Maleic anhydride is a cyclic unsaturated dicarboxylic acid anhydride with the chemical formula C4H2O3. It is a white solid that is soluble in water and polar organic solvents. Maleic anhydride is derived from maleic acid and is commonly used in various industrial applications.

Maleic anhydride is primarily used as a precursor for the production of other chemicals, such as unsaturated polyester resins, 1,4-butanediol, and lubricant additives. It undergoes addition reactions with different compounds to form products with diverse properties.

Due to its reactivity, maleic anhydride is employed in the production of paints, coatings, adhesives, and plastics. It is also used as a crosslinking agent in the manufacturing of modified starches and as a corrosion inhibitor in water treatment processes. Additionally, maleic anhydride finds applications in the synthesis of pharmaceutical intermediates, agricultural chemicals, and surfactants.

However, it is important to note that maleic anhydride is a hazardous substance and appropriate safety measures should be taken during handling and usage. Protective equipment, such as gloves and goggles, should be worn, and exposure to the compound should be avoided to prevent potential health risks.

Here are some common applications of Maleic anhydride:

1. Resins and Polymers: Maleic anhydride is used as a key raw material for the synthesis of resins and polymers. It undergoes addition reactions with alcohols, amines, and other compounds to produce unsaturated polyesters, maleate esters, and other types of polymers used in the production of various plastics, elastomers, coatings, and adhesives.

2. Oil and Lubricant Additives: Maleic anhydride is employed as an additive in oils and lubricants to enhance their oxidation stability, viscosity index, and total base number. It provides excellent antioxidative properties, thereby extending the lifespan of mechanical equipment and engines.

3. Surfactants and Adhesives: Maleic anhydride serves as a raw material or intermediate for the synthesis of surfactants and adhesives. It improves the adhesion, suspension stability, and water resistance of adhesives and can be used to produce detergents, emulsifiers, and dye assistants as well.

4. Preparation of 1,4-Butanediol: Maleic anhydride is an important raw material in the production of 1,4-butanediol. It reacts with 1,4-butanediol to form 1,4-butanediol mono(maleate), which can be further hydrogenated to obtain 1,4-butanediol. This compound is used in the production of polyester resins, solvents, and plastics.

5. Water Treatment and Corrosion Inhibitors: Maleic anhydride can be used as a chelating agent and scale inhibitor in water treatment to prevent scale formation and pipe blockages. Additionally, it serves as a corrosion inhibitor for metal surfaces, protecting metal equipment and structures from corrosion.

In addition to these applications, Maleic anhydride is utilized in the production of dyes and pigments, processing agents for paper and textiles, intermediates for pesticides and veterinary medicines, and more. It plays a vital role in various industries, and new applications are continually being discovered and developed.
