It is a white crystals subliming at 345°C slightly soluble in water, alcohol and acetic acid (insoluble in benzene). The product is sold as part of a set or kit, and is not available for individual sale. The main industrial uses of purified isophthalic acid are for the production of polyethylene terephthalate (PET) resin and for the production of unsaturated polyester resin (UPR) and other types of coating resins. 1459-93-4: einecs no. CAS No: 200013-64-5; Molecular Weight: Molecular Formula: Boiling Point: Melting Point: Properties Safety and Handling 0 Suppliers Unit. Isophthalic acid: Catalog No. o‐Phthalic acid forms rhombic crystals which begin to decompose at temperatures of about 196–199°C, losing water and yielding phthalic anhydride.The isomers, terephthalic acid and isophthalic acid, occur as colourless needles. 345 degrees C at atmospheric pressure without undergoing a transition to the liquid phase. Their reactions with bases, called "neutralizations", are accompanied by the evolution of substantial amounts of heat. Phthalic acid is an aromatic dicarboxylic acid, with formula C 6 H 4 (CO 2 H) 2.It is an isomer of isophthalic acid and terephthalic acid.Although phthalic acid is of modest commercial importance, the closely related derivative phthalic anhydride is a commodity chemical produced on a large scale.
