Iyini i-Sulfoisophthalic Acid Monosodium Salt CAS 6362-79-4?

Usawoti we-5-Sulfoisophthalic acid monosodium (CAS 6362-79-4, igama lesiNgisi: 5-sulfoisophthalic acid monosodium (usawoti) uyisithako esibalulekile se-organic synthetic, esiyingxenye ye-sulfonated modified aromatic dicarboxylic acid derivatives. Isakhiwo saso sama-molecule sisekelwe ku-isophthalic acid njengeqembu eliyinhloko, neqembu le-sulfonic acid (-SO₃H) elethulwa endaweni yesi-5 yendandatho ye-benzene futhi lakha usawoti one-sodium.

Ngokombono wezakhiwo zomzimba nezamakhemikhali, usawoti we-monosodium we-5-Sulfoisophthalic acid uvame ukubonakala njengompuphu omhlophe, onephuzu lokuncibilika elingu-373℃. Ku-20℃, ubuningi bawo bungu-1.87, futhi unokuncibilika okuhle kwamanzi (380g/L). Ku-20℃, i-acidity coefficient yayo (pKa) ingu-4.1, kanti ku-23℃, i-LogP yayo ingu--1.7. Sekukonke. I-Sodium m-5-sulfonate izinzile ngokwemvelo futhi incibilika kalula emanzini, okwenza ifanelekele izimo zokusetshenziswa kwesistimu esekelwe emanzini.

Isicelo

1. Insimu yezinto ze-polymer

Usawoti we-monosodium we-5-Sulfoisophthalic acid usetshenziswa njenge-monomer ye-copolymer ekukhiqizweni kwe-"polyester eguquliwe": i-copolymerized nge-terephthalic acid kanye ne-ethylene glycol, futhi amaqembu e-sodium sulfonate aqaliswa ukuthuthukisa i-hydrophilicity kanye nokudaya kwe-polyester, esetshenziselwa ukukhiqiza imicu ye-polyester edayiseka kalula kanye nezingubo ze-polyester ezisekelwe emanzini.

Ukulungiswa kwe-"ion exchange resin": Amaqembu e-Carboxyl namaqembu e-sodium sulfonate angasetshenziswa njengamaqembu okushintshana kwama-ion ukuze kuhlanganiswe ama-water softening kanye nama-heavy metal ion adsorption resins.

2. Insimu yokunyathelisa nokufaka udayi ngezindwangu

Njenge-"ejenti yokulinganisa": Ekudayini imicu yokwenziwa efana ne-polyester ne-nylon, ukwengeza i-sodium isophthalic acid 5-sulfonate kungalawula izinga lokumuncwa kodayi, kugweme ukudaya okungalingani, futhi kuthuthukise ukufana kanye nokuqina kombala wokudaya kwendwangu.

3. Insimu yezembozo kanye ne-glue.

"Izembozo ezisekelwe emanzini": Njengesengezo esisebenzayo, usawoti we-monosodium we-5-Sulfoisophthalic acid uthuthukisa ukusabalala kanye nokumelana namanzi kwesembozo, kunciphisa ukuhlukaniswa kwesembozo, futhi kuthuthukisa ukunamathelana phakathi kwesembozo kanye ne-substrate.

"Ingcina esekwe emanzini" eguquliwe: I-Copolymerized nge-acrylate, i-5-Sulfoisophthalic acid monosodium salt ithuthukisa ukumelana nesimo sezulu kanye nokuguquguquka kwensigcina, efanelekile ezintweni zokubopha ezifana nokhuni nepulasitiki.
