Iyini i-Isophthalic acid CAS 121-91-5?

I-Isophthalic acid iyikristalu engenambala ecwebezelwe emanzini noma ethanol. Incibilika kancane emanzini, ayincibiliki ku-benzene, i-toluene ne-petroleum ether, incibilika ku-methanol, i-ethanol, i-acetone ne-glacial acetic acid. I-Isophthalic acid inengozi ethile, ngempushana noma izinhlayiya ezixutshwe nomoya, ukuqhuma kothuli kungase kwenzeke.

Isicelo

I-Isophthalic acid isetshenziswa kakhulu ekukhiqizeni i-polyester resin engagcwele, umunwe wesihlahla se-PET copolymer kanye ne-alkyd resin. Ngaphezu kwalokho, i-isophthalic acid njengempahla eluhlaza ingasetshenziswa futhi ukulungisa i-polyisophthalic acid allyl ester (DAIP) resin, esetshenziswa kabanzi ekwenzeni izingxenye eziqinile neziyinkimbinkimbi zokushisa ezisezingeni eliphezulu kanye nama-laminate afakwe ngaphakathi. Ukulungiswa kwe-diethyl isophthalate (DEIP) njenge-solvent ekhethekile ye-Chemicalbook ekukhiqizeni i-toluene diisocyanate; Ukulungiswa kwe-polybenzimidazole esetshenziswa njenge-adhesive ye-aluminium alloy, insimbi engagqwali nezinye izinto zensimbi, isakhiwo sezinyosi zensimbi, ifilimu ye-polyimide, i-silicon wafer nezinye izinto; I-Diisooctyl isophthalate, i-plasticizer ewuketshezi kawoyela engenambala ehambisana kahle ne-PVC, i-nitrocellulose, i-polystyrene namanye ama-resin, yalungiswa.
