What is itaconic acid:

Itaconic acid is also known as methylene succinic acid and methylene succinic acid.

It is an unsaturated acid containing conjugated double bonds and two carboxyl groups. It is rated as one of the top 12 value-added chemicals from biomass. It is a white crystal or powder at room temperature, with a melting point of 165-168°C and a specific gravity of 1.632. It is soluble in water, ethanol and other solvents.

Itaconic acid contains an unsaturated double bond and two active carboxyl groups, which gives it active chemical properties and can undergo various addition reactions, esterification reactions and polymerization reactions.

At the same time, it is destined to have a wide range of applications. It is used to produce industrial raw materials such as acrylic fiber, synthetic resin, plastics, rubber, drugs, surfactants, non-toxic food packaging materials, herbicides, descaling agents, dental adhesives, etc.

Nature and stability:

  1. Avoid contact with alkalis and oxidants.
  2. The product has low toxicity and little harm to health, but its vapor is toxic. The equipment should be closed during production, and the operators should wear protective gear.
  3. The chemical properties are relatively active, and it can be polymerized by itself or with different numbers of other monomers such as acrylonitrile and styrene. The vapor is toxic and easily decomposes when overheated.
  4. Exist in the flue gas.

storage method

       sealed package. Store in a cool, dry place away from light. It needs to be put in a paper drum lined with plastic bags and stored tightly. Pay attention to moisture, heat and oxidant protection. Store and transport according to general chemical regulations


  1. Can be used as an acidity agent, pH adjuster, and metal chelating agent. An important intermediate in the chemical synthesis industry, it can be used in the manufacture of synthetic resins, rubbers, plastics, lubricant additives, boiler scale removers, adhesives, detergents, herbicides and more. The ester is also an important raw material for plasticizers.
  2. In recent years, research and application of itaconic acid as a monomer for synthesizing copolymers has been progressing. One of the important aspects is the use of itaconic acid copolymers as water treatment agents and chemical cleaners. The features of descaling are that it can be performed when the equipment is operating normally, the cleaning conditions are mild, no acid needs to be added to lower the pH value, and the cleaning time is slightly longer ( Usually 10 to 60 days). ..
  3. As a comonomer of polyacrylonitrile, its synthetic fibers can improve the dyeing performance of synthetic fibers. It can also be used to prepare plasticizers, lubricant additives, dispersion emulsions for coatings, etc.
  4. Itaconic acid and its polymers can be made into highly efficient deodorants by adding a small amount of natural substances that react with acidic odors such as ammonia, amine alkaline odor, and hydrogen sulfide. It can also be deodorized into paper. function. , Plastic films and other products.
  5. SBR latex can be made using the copolymerization of itaconic acid, styrene and butadiene. It can be used to coat paper to make the paper stronger and brighten the print pattern. Metal and concrete coatings are easy to color and are subject to natural conditions. It is used as a paint additive to improve the quality of paint. Used for carpet sizing, synthetic carpets can be made durable.
  6. Itaconic acid is polymerized with acrylic acid or methacrylic acid or its ester to make a resin, which can be used for surface coating and emulsion paint. As a leather coating, it can increase the plasticity of the leather. Used as a coating for automobiles, appliances and refrigeration, it has the advantages of strong adhesion, beautiful color and resistance to bad weather. When used as an electrophoretic coating, it exhibits excellent adhesion. The addition of polyvalent metal oxides can result in dental adhesives with excellent extrusion performance, strong adhesiveness, and excellent physiological adaptability. The addition of chloroalkyldimethylbenzylammonium chloride can create a water-soluble coating of food packaging materials and reduce bacterial contamination of the packaging surface.
  7. Itaconic acid ester is a raw material for citraconic acid, mesaconic acid, and itaconic anhydride.

Itaconic acid contains two active carboxyl groups and a double bond in its molecule. The double bond and carboxyl group are in a conjugate relationship, which makes itaconic acid very active. In addition to self-polymerization, it can also be combined with different numbers of other monomers. Polymerization to form polymeric polymers, so it is widely used in the chemical synthesis industry.


Biological method: Using carbohydrates as raw materials, adding nitrogen sources and inorganic salts, it is obtained by the action of Aspergillus terreus.
Chemical method:

  1. Using citric acid as raw material, heating in the presence of a catalyst to obtain citraconic acid, and then heating to 220 degrees for isomerization to obtain itaconic acid.
  2. It is prepared from isocitric acid, aconitic acid or aconitic anhydride as raw materials.
  3. Using succinic anhydride or succinic diester as raw material, react with formaldehyde under the catalysis of thorium salt to obtain citraconic acid, and heat isomerization to obtain itaconic acid.
  4. It is derived from the esterification, addition, methylene and hydrolysis of maleic anhydride.

Note: This production method is for reference only, and the actual production method should be based on actual production needs.
