Sulfoisophthalic Acid Monosodium Ntsev CAS 6362-79-4
5-Sulfoisophthalic acid monosodium ntsev (CAS 6362-79-4, Lub npe lus Askiv: 5-sulfoisophthalic acid monosodium (ntsev) yog ib qho tseem ceeb ntawm cov organic synthetic intermediate, uas yog cov sulfonated modified aromatic dicarboxylic acid derivatives. Nws cov qauv molecular yog raws li isophthalic acid ua pawg niam txiv, nrog rau pawg sulfonic acid (-SO₃H) tau qhia ntawm qhov chaw 5 ntawm lub nplhaib benzene thiab tsim cov ntsev nrog sodium.
Los ntawm qhov pom ntawm cov khoom siv lub cev thiab tshuaj lom neeg, 5-Sulfoisophthalic acid monosodium ntsev feem ntau tshwm sim ua hmoov dawb, nrog lub ntsiab lus yaj ntawm 373 ℃. Ntawm 20 ℃, nws qhov ceev yog 1.87, thiab nws muaj kev yaj dej zoo (380g / L). Ntawm 20 ℃, nws cov coefficient acidity (pKa) yog 4.1, thiab ntawm 23 ℃, nws LogP yog -1.7. Tag nrho. Sodium m-5-sulfonate ruaj khov hauv qhov xwm txheej thiab yooj yim yaj hauv dej, ua rau nws tsim nyog rau cov xwm txheej siv dej.

1. Cov ntaub ntawv polymer
5-Sulfoisophthalic acid monosodium ntsev yog siv los ua copolymer monomer rau kev tsim cov "polyester hloov kho": copolymerized nrog terephthalic acid thiab ethylene glycol, thiab sodium sulfonate pawg tau qhia los txhim kho hydrophilicity thiab dyeability ntawm polyester, uas yog siv los tsim cov polyester fibers yooj yim dyeable thiab dej-raws li polyester coatings.
Kev npaj ntawm "ion exchange resin": Carboxyl pawg thiab sodium sulfonate pawg tuaj yeem siv ua ion exchange pawg rau kev tsim cov dej softening thiab cov hlau hnyav ion adsorption resins.
2. Kev luam ntawv thiab zas xim rau ntaub
Ua ib tug "leveling agent": Hauv kev zas xim ntawm cov khoom siv hluavtaws xws li polyester thiab nylon, ntxiv sodium isophthalic acid 5-sulfonate tuaj yeem tswj cov xim zas, tsis txhob zas xim tsis sib xws, thiab txhim kho qhov sib xws thiab xim ceev ntawm cov ntaub zas xim.
3. Cov txheej txheem thiab cov nplaum.
Rau "cov txheej txheem dej": Ua ib qho khoom siv ntxiv, 5-Sulfoisophthalic acid monosodium ntsev txhim kho qhov kev sib kis thiab kev tiv thaiv dej ntawm cov txheej txheem, txo qhov kev tawg ntawm cov txheej txheem, thiab txhim kho qhov kev sib txuas ntawm cov txheej txheem thiab cov khoom siv hauv qab.
Cov "nplaum ua los ntawm dej" uas tau hloov kho: Copolymerized nrog acrylate, 5-Sulfoisophthalic acid monosodium ntsev ua rau cov nplaum tiv taus huab cua thiab yooj ywm dua, tsim nyog rau kev sib txuas cov ntaub ntawv xws li ntoo thiab yas.
