Kev piav qhia:
Isophthalic acid yog ib qho organic compound nrog cov mis C6H4 (CO2H) 2. Cov khoom tsis muaj xim no yog ib qho isomer ntawm phthalic acid thiab terephthalic acid. Cov aromatic dicarboxylic acids no yog siv ua cov precursors (hauv daim ntawv ntawm acyl chlorides) rau cov polymers tseem ceeb hauv kev lag luam, piv txwv li cov khoom siv hluav taws kub Nomex. Sib xyaw nrog terephthalic acid, iso phthalic acid yog siv rau hauv kev tsim cov resins rau cov fwj dej haus. Cov polymer ua tau zoo poly benzimidazole yog tsim los ntawm iso phthalic acid.

Kev Siv
Isophthalic acid yog siv ua ib qho nruab nrab rau cov polyesters tsis muaj zog uas ua haujlwm tau zoo, cov resins rau cov txheej txheej, cov xim pleev xim uas khov kho, cov tsho tiv no gel thiab cov khoom hloov kho ntawm polyethylene terephthalate rau lub raj mis. Nws ua haujlwm ua cov khoom ua ntej rau cov khoom siv tiv thaiv hluav taws nomex nrog rau siv rau hauv kev npaj cov polymer ua haujlwm tau zoo polybenzimidazole. Nws kuj tseem siv ua cov khoom siv rau kev tsim cov ntaub ntawv rwb thaiv tsev.
Purified Isophthalic Acid (PIA) feem ntau yog siv ua cov khoom siv nruab nrab rau kev ua haujlwm siab UPR, cov resins rau cov txheej txheem, cov xim pleev xim siab, cov txheej gel, cov khoom hloov kho ntawm PET rau lub raj mis.
