Yintoni iSulfoisophthalic Acid Monosodium Salt CAS 6362-79-4?

Ityuwa ye-5-Sulfoisophthalic acid monosodium (CAS 6362-79-4, igama lesiNgesi: 5-sulfoisophthalic acid monosodium (ityuwa) sisixhobo esibalulekileyo se-organic synthetic, esikwi-sulfonated modified aromatic dicarboxylic acid derivatives. Ulwakhiwo lwayo lwe-molecular lusekelwe kwi-isophthalic acid njengeqela elingumzali, kunye neqela le-sulfonic acid (-SO₃H) elingeniswe kwindawo yesi-5 yendandatho ye-benzene kwaye lenza ityuwa ene-sodium.

Ngokwembono yeempawu zomzimba nezekhemikhali, ityuwa ye-5-Sulfoisophthalic acid monosodium idla ngokubonakala njengomgubo omhlophe, oneqondo lokunyibilika elingama-373℃. Kwi-20℃, uxinano lwayo yi-1.87, kwaye inokunyibilika kakuhle kwamanzi (380g/L). Kwi-20℃, i-acidity coefficient yayo (pKa) yi-4.1, kwaye kwi-23℃, i-LogP yayo yi--1.7. Lilonke. I-Sodium m-5-sulfonate izinzile ngokwendalo kwaye inyibilika lula emanzini, nto leyo eyenza ukuba ifaneleke kwiimeko zokusetyenziswa kwenkqubo esekwe emanzini.

Isicelo

1. Intsimi yezinto zepolymer

Ityuwa ye-5-Sulfoisophthalic acid monosodium isetyenziswa njenge-copolymer monomer ukuvelisa "i-polyester eguquliweyo": i-copolymerized nge-terephthalic acid kunye ne-ethylene glycol, kwaye amaqela e-sodium sulfonate aziswa ukuphucula i-hydrophilicity kunye ne-dyeability ye-polyester, esetyenziselwa ukuvelisa iifayibha ze-polyester ezidaywa lula kunye neengubo ze-polyester ezisekelwe emanzini.

Ukulungiswa kwe-"ion exchange resin": Amaqela e-Carboxyl kunye namaqela e-sodium sulfonate angasetyenziswa njengamaqela e-ion exchange ukuze kuhlanganiswe i-water softening kunye ne-heavy metal ion adsorption resins.

2. Intsimi yokuprinta kunye nokudaya ilaphu

Njenge-"arhente yokulinganisa": Ekudayini iifayibha zokwenziwa ezifana ne-polyester kunye ne-nylon, ukongeza i-sodium isophthalic acid 5-sulfonate kunokulawula izinga lokufunxwa kwedayi, kuthintele ukudaya okungalinganiyo, kwaye kuphucule ukufana kunye nokukhawuleza kombala wokudaya ilaphu.

3. Intsimi yeengubo kunye neeglu.

Kwi "iinwele ezisekelwe emanzini": Njengesithako esisebenzayo, ityuwa ye-5-Sulfoisophthalic acid monosodium iphucula ukusasazeka kunye nokumelana namanzi kwengubo, inciphisa ukwahlukana kwengubo, kwaye iphucula ukunamathelana phakathi kwengubo kunye ne-substrate.

"Iglu esekwe emanzini" eguquliweyo: I-Copolymerized nge-acrylate, ityuwa ye-monosodium ye-5-Sulfoisophthalic acid yonyusa ukumelana kwemozulu kunye nokuguquguquka kweglu, ifanelekile kwizixhobo zokubopha ezifana nomthi kunye neplastiki.
