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

Isophthalic acid yikristale engenambala ekhazimliswe emanzini okanye ethanol. Inyibilika kancinci emanzini, ayinyibiliki kwibenzene, toluene kunye nepetroleum ether, inyibilika kwimethanol, ethanol, acetone kunye neglacial acetic acid. I-Isophthalic acid inomngcipheko othile, kunye nomgubo okanye amaqhekeza axutywe nomoya, ukuqhuma kothuli kunokwenzeka.

Isicelo

I-Isophthalic acid isetyenziswa kakhulu kwimveliso ye-polyester resin engaxutywanga, i-PET copolymer tree finger kunye ne-alkyd resin. Ukongeza, i-isophthalic acid njengento ekrwada ingasetyenziselwa ukulungisa i-polyisophthalic acid allyl ester (DAIP) resin, esetyenziswa ngokubanzi kukwenziwa kwezinto ezichanekileyo nezintsonkothileyo zobushushu obuphezulu kunye neelaminates ezifakwe ngaphakathi. Ukulungiswa kwe-diethyl isophthalate (DEIP) njenge-solvent ekhethekileyo ye-Chemicalbook ekuveliseni i-toluene diisocyanate; Ukulungiswa kwe-polybenzimidazole esetyenziselwa i-adhesive ye-aluminium alloy, insimbi engenasici kunye nezinye izinto zetsimbi, isakhiwo se-honeycomb yensimbi, ifilimu ye-polyimide, i-silicon wafer kunye nezinye izinto; I-Diisooctyl isophthalate, i-plasticizer yolwelo lwe-oyile engenambala ehambelana kakuhle ne-PVC, i-nitrocellulose, i-polystyrene kunye nezinye ii-resin, zalungiswa.
