Acid Sulfisophthalic Monosodium Nnu CAS 6362-79-4
5-Sulfoisophthalic acid nnu monosodium (CAS 6362-79-4, aha Bekee: 5-sulfoisophthalic acid monosodium (nnu) bụ ihe dị mkpa e ji emepụta ihe ndị sitere na organic, nke sitere na ihe ndị sitere na sulfonated modified aromatic dicarboxylic acid. Ọdịdị molekul ya dabere na isophthalic acid dị ka otu nne na nna, yana otu sulfonic acid (-SO₃H) ewebatara na ọnọdụ nke 5 nke mgbanaka benzene ma mepụta nnu na sodium.
Site n'echiche nke ihe ndị dị na anụ ahụ na kemịkalụ, nnu monosodium 5-Sulfoisophthalic acid na-apụtakarị dị ka ntụ ntụ ọcha, nke nwere ebe agbaze nke 373℃. Na 20℃, njupụta ya bụ 1.87, ọ nwekwara ezigbo mmiri ịgbaze (380g/L). Na 20℃, ihe mejupụtara acidity ya (pKa) bụ 4.1, na 23℃, LogP ya bụ -1.7. N'ozuzu ya. Sodium m-5-sulfonate kwụsiri ike ma na-agbaze ngwa ngwa na mmiri, na-eme ka ọ dabara adaba maka ọnọdụ ojiji sistemụ dabere na mmiri.

1. Ubi nke ihe polymer
A na-eji nnu monosodium nke 5-Sulfoisophthalic acid eme ihe dị ka monomer copolymer maka mmepụta nke "polyester agbanwere agbanwe": ejiri terephthalic acid na ethylene glycol copolymer mee copolymer, a na-ewebatakwa otu sodium sulfonate iji melite ịdị ọcha na agba nke polyester, nke a na-eji emepụta eriri polyester a na-agba agba ngwa ngwa na mkpuchi polyester nke mmiri.
Nkwadebe nke "resin mgbanwe ion": Enwere ike iji otu Carboxyl na otu sodium sulfonate dị ka otu mgbanwe ion maka njikọta nke resins na-eme ka mmiri dị nro na resins adsorption metal dị arọ.
2. Ubi mbipụta ákwà na agba agba
Dịka "ihe na-eme ka agba dị larịị": N'ịcha agba nke eriri sịntetik dịka polyester na naịlọn, itinye sodium isophthalic acid 5-sulfonate nwere ike ịchịkwa ọsọ nnabata agba, zere agba na-adịghị mma, ma melite nha na ọsọ agba nke agba ákwà.
3. Mkpuchi na ihe ndị na-ejikọ ọnụ.
Maka "mkpuchi mmiri": Dịka ihe mgbakwunye bara uru, nnu monosodium 5-Sulfoisophthalic acid na-eme ka mgbasa na iguzogide mmiri nke mkpuchi ahụ ka mma, na-ebelata mmebi nke mkpuchi ahụ, ma na-eme ka njikọ dị n'etiti mkpuchi ahụ na ihe mkpuchi ahụ dịkwuo mma.
"Nrapado dabere na mmiri" emezigharịrị: Nnu monosodium 5-Sulfoisophthalic acid nke ejiri acrylate mee ka ihe mgbakwụnye ahụ dịkwuo mma, ọ dịkwa mma maka ihe ndị dịka osisi na plastik.
