The organic substance Isophthalic Acid has the chemical formula C6H4(CO2H)2. An isomer of both phthalic acid and terephthalic acid makes up this colourless solid. The manufacturing of polyethylene terephthalate (PET) resin, unsaturated polyester resin (UPR), and other coated resins are the main industrial uses of pure isophthalic acid (PIA). One of benzenedicarboxylic acid's three isomers, along with phthalic and terephthalic acids, is isophthalic acid. A billion kilogrammes of Isophthalic Acid are created annually by oxidising meta-xylene with oxygen. Cobalt and manganese are used as a catalyst in the process. Lotte Chemical Corporation is the largest manufacturer of isophthalic acid in the world. Chromic acid can be utilised as an oxidant in a laboratory setting. It can also be produced by combining potassium formate and potassium meta-sulfobenzoate or meta-bromobenzoate (terephthalic acid is also formed in the last case). The barium salt is very soluble in water in its hexahydrate form (a distinction between phthalic and terephthalic acids). Mesitylene can be converted to uvitic acid, also known as 5-methylisophthalic acid, through oxidation, or pyroracemic acid can be condensed with baryta water.
