Pyromellitic dianhydride (PMDA) yog ib qho khoom siv tseem ceeb hauv kev lag luam organic synthesis, nrog rau cov khoom siv tseem ceeb rau kev tsim cov khoom siv tshuaj tshiab thiab cov khoom siv tshuaj zoo uas muaj nqis ntxiv. Nws feem ntau yog siv rau kev tsim cov polyimide monomers, thiab kuj tseem siv tau ua tus neeg sawv cev rau epoxy resin thiab tus neeg sawv cev sib txuas rau polyester resin, siv rau hauv kev tsim cov xim xiav phthalocyanine thiab qee cov khoom siv tseem ceeb, thiab lwm yam, thiab muaj ntau yam kev siv. Pyromellitic dianhydride, tseem hu ua homoanhydride, muaj cov qauv molecular tshwj xeeb thiab tuaj yeem siv los tsim cov ntaub ntawv uas tiv taus cua sov, rwb thaiv tsev hluav taws xob thiab tshuaj lom neeg, ntawm cov kev siv tseem ceeb tshaj plaws yog ua ib txheej ntawm polyimide. Nws yog synthesized nrog aromatic diamine kom tau txais polyimide yas, tab sis qhov huv ntawm pyromellitic dianhydride yog siab heev, uas yuav tsum tau ntau dua 99%.
