I-Isophthalic acid CAS 121-91-5
I-Isophthalic acid iyikristalu engenambala eqiniswe emanzini noma e-ethanol. Incibilika kancane emanzini, ayincibiliki ku-benzene, i-toluene kanye ne-petroleum ether, incibilika ku-methanol, i-ethanol, i-acetone kanye ne-glacial acetic acid. I-Isophthalic acid inengozi ethile, uma impuphu noma izinhlayiya zixubene nomoya, ukuqhuma kothuli kungenzeka.

I-Isophthalic acid isetshenziswa kakhulu ekukhiqizweni kwe-resin ye-polyester engagcwalisiwe, i-PET copolymer tree finger kanye ne-resin ye-alkyd. Ngaphezu kwalokho, i-isophthalic acid njengezinto zokusetshenziswa ingasetshenziswa futhi ukulungiselela i-resin ye-polyisophthalic acid allyl ester (DAIP), esetshenziswa kabanzi ekwenziweni kwezingxenye zokuvikela ukushisa eziphakeme neziyinkimbinkimbi kanye nama-laminate afakwe emanzini. Ukulungiswa kwe-diethyl isophthalate (DEIP) njengesithako esikhethekile se-Chemicalbook ekukhiqizweni kwe-toluene diisocyanate; Ukulungiswa kwe-polybenzimidazole esetshenziswa njengesinamathelisi se-aluminium alloy, insimbi engagqwali nezinye izinto zensimbi, isakhiwo se-metal honeycomb, ifilimu ye-polyimide, i-silicon wafer nezinye izinto; I-Diisooctyl isophthalate, i-plasticizer ewuketshezi kawoyela engenambala ehambisana kahle ne-PVC, i-nitrocellulose, i-polystyrene nezinye izinhlayiya, kwalungiswa.
25kg/isigubhu noma ngokwezidingo zamakhasimende.
