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

I-asidi ye-Isophthalic yikristale engenambala eyenziwe ngamanzi okanye i-ethanol. Inyibilika kancinci emanzini, ayinyibiliki kwi-benzene, i-toluene kunye ne-petroleum ether, inyibilika kwi-methanol, i-ethanol, i-acetone kunye ne-glacial acetic acid. I-asidi ye-Isophthalic inomngcipheko othile, xa ixutywe nomgubo okanye amasuntswana nomoya, ukuqhuma kothuli kunokwenzeka.

Isicelo

I-Isophthalic acid isetyenziswa kakhulu ekuveliseni i-unsaturated polyester resin, i-PET copolymer tree finger kunye ne-alkyd resin. Ukongeza, i-isophthalic acid njengezinto eziluhlaza ingasetyenziselwa ukulungiselela i-polyisophthalic acid allyl ester (DAIP) resin, esetyenziswa kakhulu ekuveliseni iindawo ezikhuselayo ezichanekileyo nezintsonkothileyo kunye ne-laminates ezifakwe kwi-impregnated. Ukulungiswa kwe-diethyl isophthalate (DEIP) njenge-Chemicalbook solvent ekhethekileyo ekuveliseni i-toluene diisocyanate; Ukulungiswa kwe-polybenzimidazole esetyenziswa njenge-adhesive ye-aluminium alloy, i-stainless steel kunye nezinye izinto zesinyithi, isakhiwo se-metal honeycomb, ifilimu ye-polyimide, i-silicon wafer kunye nezinye izinto; I-Diisooctyl isophthalate, i-oyile engenambala, i-plasticizer enokuhambelana kakuhle ne-PVC, i-nitrocellulose, i-polystyrene kunye nezinye ii-resin, yalungiswa.
