What is Maleic Anhydride?

Maleic anhydride is an organic compound that belongs to the class of cyclic dicarboxylic anhydrides. It is derived from the hydrocarbon butene and is commonly represented by the chemical formula C4H2O3. It is a colourless solid that has a characteristic acrid odor. It is highly reactive and readily undergoes reactions with various compounds. One of the significant applications of maleic anhydride is its use in the production of various polymers. When reacted with certain chemicals, maleic anhydride can undergo a process called “copolymerization” to form copolymers such as maleic anhydride-styrene copolymer and maleic anhydride-vinyl acetate copolymer. These copolymers possess desirable properties like adhesion, high melting points, and resistance to chemicals, making them useful in industries such as adhesives, coatings, and plastics.

Maleic anhydride also serves as a precursor for the production of other chemicals. It can be used in the synthesis of 1,4-butanediol, a versatile chemical used in the manufacturing of plastics, fibers, and solvents. Moreover, it finds applications in the production of agricultural chemicals, pharmaceuticals, and as a cross-linking agent in resins.

Properties of Maleic Anhydride

Maleic anhydride possesses several notable properties. Here are some key characteristics of this organic compound:

Physical state

It is a solid at room temperature that appears as colourless or white crystals or flakes.


Maleic anhydride has a distinct, pungent odor. The smell can be described as acrid or sharp.


It is highly reactive and readily undergoes reactions with various compounds, including alcohols, amines, and water. It can react exothermically with water, leading to the production of maleic acid.

Melting and Boiling Points

Maleic anhydride has a relatively high melting point of around 52-54 degrees Celsius (126-129 degrees Fahrenheit). It does not have a well-defined boiling point, as it tends to decompose before reaching its boiling point.


It is sparingly soluble in water, but it dissolves well in organic solvents such as acetone, benzene, and ethanol.


Maleic anhydride is relatively stable under normal conditions, but it can slowly hydrolyze in the presence of moisture, converting to maleic acid.


It can be irritating to the skin, eyes, and respiratory system. Prolonged or repeated exposure may cause dermatitis or respiratory sensitization. Proper safety precautions should be taken when handling this compound.

Maleic Anhydride Applications

Maleic anhydride has diverse applications across various industries. Some notable uses of maleic anhydride include:

  1. Polymer Production: It is extensively utilized in the production of polymers. Through copolymerization with other compounds, such as styrene or vinyl acetate, it forms copolymers with desirable properties like adhesion, high melting points, and chemical resistance. These copolymers find applications in adhesives, coatings, and plastics.
  2. 1,4-Butanediol (BDO) Synthesis: Maleic anhydride is a precursor in the synthesis of 1,4-butanediol (BDO). BDO is a versatile chemical used in the production of plastics, fibers, solvents, and other industrial applications. Maleic anhydride undergoes a catalytic hydrogenation process to convert it into BDO.
  3. Agricultural Chemicals: It is employed in the production of agricultural chemicals, including herbicides, insecticides, and fungicides. It serves as a building block in the synthesis of active ingredients for these formulations.
  4. Pharmaceutical Intermediates: Maleic anhydride finds application in the pharmaceutical industry as a starting material for the synthesis of various intermediates. These intermediates are utilized in the production of pharmaceutical compounds and active ingredients.
  5. Cross-Linking Agent: It acts as a cross-linking agent in the production of resins. It helps to improve the performance and durability of resins, making them suitable for applications such as adhesives, composites, and coatings.
  6. Other Uses: Maleic anhydride has additional applications in the production of flavours, food additives, dyes, and as a chemical intermediate in various processes.

The wide range of applications for maleic anhydride highlights its versatility and importance in various industries. However, proper handling and safety measures should be followed when working with this compound due to its reactivity and potential health risks.
