Isophthalic Acid is a white crystalline solid that is a common organic compound. It is a type of phthalic acid, which is a dicarboxylic acid that contains two carboxyl groups. Isophthalic acid has the chemical formula C8H6O4 and the systematic name benzene-1,3-dicarboxylic acid. Its molecular weight is 166.13 g/mol.
Isophthalic Acid is widely used in the production of polymers, resins, and fibers. It is an important raw material in the manufacture of polyesters, such as polyethylene terephthalate (PET), which is used in many products including plastic bottles and fibers. Isophthalic acid is also used in the production of unsaturated polyester resins, which are used in the construction, automotive, and marine industries. Isophthalic acid is usually obtained by the oxidation of meta-xylene or ortho-xylene using air or oxygen. The resulting crude isophthalic acid is then purified by sublimation or recrystallization. The purity of the final product is typically greater than 99%.
