Umunyu wa Monosodium ukomoka kuri aside ya sulfoisophthalike CAS 6362-79-4
5-Sulfoisophthalic acid monosodium salt (CAS 6362-79-4, izina ry'Icyongereza: 5-sulfoisophthalic acid monosodium (umunyu) ni ikintu cy'ingenzi cya sintetike, kigizwe n'ibikomoka kuri aside dicarboxylic aromatic modified. Imiterere ya molekile ishingiye kuri aside isophthalic nk'itsinda ry'ababyeyi, hamwe n'itsinda rya aside sulfonic (-SO₃H) ryashyizwe ku mwanya wa 5 w'impeta ya benzene rigakora umunyu urimo sodium.
Ukurikije imiterere y’umubiri n’imiti, umunyu wa monosodium wa aside 5-Sulfoisophthalic ukunze kugaragara nk’ifu yera, ifite aho ishongesha 373°C. Kuri 20°C, ubucucike bwayo ni 1.87, kandi ifite ubushobozi bwo gushonga neza mu mazi (380g/L). Kuri 20°C, aside coefficient yayo (pKa) ni 4.1, naho kuri 23°C, LogP yayo ni -1.7. Muri rusange. Sodium m-5-sulfonate irahamye kandi irashongesha mu mazi byoroshye, bigatuma ikoreshwa mu buryo bw’amazi.

1. Urwego rw'ibikoresho bya polimeri
Umunyu wa monosodium wa aside sulfoisophthalike ukoreshwa nka monomer ya copolymer mu gukora "polyester yahinduwe": copolymer ikoresheje aside terephthalike na ethylene glycol, kandi amatsinda ya sodium sulfonate arashyirwaho kugira ngo anonosore ubwiza bw'amazi n'ubushobozi bwo gusiga irangi rya polyester, ikoreshwa mu gukora insinga za polyester zoroshye gusiga irangi n'imyenda ya polyester ishingiye ku mazi.
Gutegura "resin yo guhinduranya ioni": Amatsinda ya karubokisili n'amatsinda ya sodium sulfonate ashobora gukoreshwa nk'amatsinda yo guhinduranya ioni mu gukora resin zoroshya amazi n'izikoresha ibyuma biremereye.
2. Ahantu ho gucapa no gusiga amarangi ku myenda
Nk'ikintu "gipima ubuziranenge": Mu gusiga irangi ku nsinga za sintetike nka polyester na nylon, kongeramo aside sodium isophthalic 5-sulfonate bishobora kugenga umuvuduko w'irangi, birinda gusiga irangi ritari rikwiye, kandi bikanoza uburinganire n'ubudahangarwa bw'irangi ry'imyenda.
3. Aho gusiga no gukodesha.
Ku "gusiga irangi rishingiye ku mazi": Nk'inyongeramusaruro ikora, umunyu wa monosodium wa 5-Sulfoisophthalic utuma irangi ritambuka neza kandi rigahangana n'amazi, ugabanya gutandukana kw'irangi, kandi ukongera uburyo irangi rifatana n'irangi.
"Kole ishingiye ku mazi" yahinduwe: Ikozwe muri akrilate, umunyu wa monosodium wa 5-Sulfoisophthalic acid wongera ubushobozi bwo guhangana n'ikirere no koroshya imiterere y'ikole, ikaba ikwiriye ibikoresho byo gufatanya nk'ibiti na pulasitiki.
