Itaconic Acid

Description

ITACONIC ACID
Itaconic acid, or methylenesuccinic acid, is an organic compound that is one of the three acids obtained by the distillation of citric acid. Itaconic acid is a white crystalline powder that is soluble in water, ethanol and acetone. It has the molecular formula C5H6O4 and molecular weight 130.10. The other two acids formed from the distillation of citric acid are citraconic and mesaconic acids.
ITACONIC ACID APPLICATIONS
Itaconic acid is a white colourless crystalline carboxylic acid obtained by the fermentation of carbohydrates and used in the manufacture of synthetic resins. It occurs in some fermentations of sugars.
Itaconic acid and its polymers can be made into effective deodorant by adding a little natural substance, they can react with alkaline or acidic odour such as ammonium, amine, and hydrogen sulfide. They can also be utilized in paper and plastic thin film with deodoring function. Itaconic acid can copolymerize with styrene and butadiene to prepare SBR latex, which is widely, used in paper coatings, metal and concrete paint. It is used in paints to improve quality and used as fibre carpet sizing agent to make carpet more endurable. Itaconic acid can react with acrylic and methacrylic acid or their esters to prepare resins which can be widely used in emulsion coating, leather coating, coatings for car, refrigerator and other electrical appliances to improve adhesion, colour and weather resistance. They are also used in eletroporetical coating with excellent adhesion, in dental binder with the help of metal oxides. With chloroalkyl dimethyl benzylammonium chloride added, they can be used to prepare water-soluble coating for food packaging to reduce bacteria contamination. Esters of Itaconic acid can be used in paint, ion-exchange resin, lubricant, binder, plasticizer, sealant and molding plastics.
Some other Itaconic acid derivatives are used in medicine, cosmetics, lubricant, thickener, herbicide and wool modifier.
