Golden Dyechem introduces Purified Isophthalic Acid (PIA), an organic compound with the formula C6H4(CO2H)2, presenting a colorless solid that stands as a key component in the production of polyethylene terephthalate (PET) resin and unsaturated polyester resin (UPR). PIA, a structural isomer of phthalic acid and terephthalic acid, exemplifies our commitment to clarity and innovation in the chemical industry.
Unique Crystalline Structure:
Crystalline isophthalic acid forms infinite chains through hydrogen bonds, creating a unique and stable structure. This characteristic contributes to its effectiveness in various chemical processes, ensuring its stability and reliability in industrial applications.
Large-Scale Production:
Produced on a massive scale, PIA is synthesized by oxidizing meta-xylene with oxygen, employing a cobalt-manganese catalyst. This billion-kilogram-per-year process reflects the scale and importance of PIA in the chemical industry, underlining its significance as a foundational component in the production of essential resins.
Laboratory Synthesis:
In laboratory settings, PIA can be synthesized using chromic acid as the oxidant. Additionally, it can arise from fusing potassium meta-sulfobenzoate or meta-bromobenzoate with potassium formate, showcasing the adaptability of PIA synthesis methods.
PIA plays a pivotal role in the production of PET resin, a widely-used material for various applications, including packaging and textiles. Additionally, PIA contributes significantly to the manufacturing of unsaturated polyester resin (UPR) and other coa
