GENERAL DESCRIPTION & APPLICATIONS
Itaconic Acid  (also called Methylene Succinic Acid)  is a white crystalline carboxylic acid obtained by the fermentation of carbohydrates. It is soluble in water, ethanol and acetone. Unsaturated solid bond makes a conjugated system with carbonly group. It is used in the field of;
  • Co-monomer to prepare acrylic fibers and rubbers, reinforced glass fiber, artificial diamonds and lens
  • Additive in fibers and ion exchange resins to increases abrasion, waterproofing, physical resistance, dying affinity and better duration
  • Water treatment system to prevent contamination by metallic alkali
  • As binder and sizing agent in non-weaving fibers, paper and concrete paint.

The end applications of itaconic acid and its esters include in the field of co-polymerizations, plasticizers, lubricant oil, paper coating. carpets for better duration, adhesives, coatings, paints, thickener, emulsifier, surface active agents,  pharmaceuticals and printing chemicals.

GENERAL DESCRIPTION OF DICARBOXYLIC ACID
Dicarboxylic acid is a compound containing two carboxylic acid, -COOH, groups. Examples are shown in table. In substitutive nomenclature their names are formed by adding -dioic' as a suffix to the name of the parent compound. They can yield two kinds of salts, as they contain two carboxyl groups in its molecules.

There are almost infinite esters obtained from thousands of potential starting materials. Esters are formed by removal of water from an acid and an alcohol, e.g., carboxylic acid esters, phosphoric acid esters, and sulfonic acid esters. Carboxylic acid esters are used as in a variety of direct and indirect applications. Lower chain esters are used as flavouring base materials, plasticizers, solvent carriers and coupling agents. Higher chain compounds are used as components in metalworking fluids, surfactants, lubricants, detergents, oiling agents, emulsifiers, wetting agents textile treatments and emollients, They are also used as intermediates for the manufacture of a variety of target compounds. The almost infinite esters provide a wide range of viscosity, specific gravity, vapor pressure, boiling point, and other physical and chemical properties for the proper application selections.
