Isophthalic acid CAS 121-91-5
Overview
Isophthalic acid (IPA for short), also known as 1,3-phthalic acid or isophthalic acid, has strong heat resistance, hydrolysis resistance and chemical resistance, and can undergo salt formation, dehydration, hydrogenation, halogenation, etc. Reaction, the biggest use is as an intermediate Chemicalbook body for the production of unsaturated polyester resins, followed by the production of polyester resins, alkyd resins (mainly used for paint manufacturing) and printing inks. In addition, it can also be used to reinforce plastics and packaging, to produce film film couplers, paints and polyester fiber dyeing modifiers, and medicines. It has a broad development and utilization prospects.
