Disodium EDTA CAS:139-33-3 Wogulitsa Wopanga

Disodium ya EDTA, yomwe imadziwikanso kuti Disodium edetate dihydrate, ndi chinthu chabwino chogwirizanitsa zinthu mu chemistry. Ili ndi ma atomu asanu ndi limodzi ogwirizanitsa zinthu, ndipo chopangidwacho chimatchedwa chelate. EDTA nthawi zambiri imagwiritsidwa ntchito pogwirizanitsa zinthu, ndipo nthawi zambiri imagwiritsidwa ntchito kudziwa kuchuluka kwa ayoni achitsulo. Disodium ya EDTA ndi mtundu wa chakudya chowonjezera chomwe chimaloledwa ndi GB2760, chomwe chingalepheretse kapena kuchedwetsa kusintha kwa mtundu, okosijeni, kusinthasintha kwa kutentha, ndi zina zotero. Mchere wa disodium wa Ethylenediaminetetraacetic acid umagwiritsidwa ntchito kwambiri m'makampani opanga nsalu. Nthawi zambiri umagwiritsidwa ntchito kusungunula limescale. Umagwiritsidwa ntchito m'makampani opanga nsalu, zamkati ndi mapepala komanso mu mankhwala a chelation. Mu zodzoladzola, umagwira ntchito ngati chotetezera kutentha. Umagwira ntchito ngati choletsa dzimbiri ku chitsulo cha kaboni m'mafakitale. Umagwiranso ntchito ngati chowonjezera chakudya. Disodium Dihydrogen EDTA ndi chinthu choteteza kutentha komanso choteteza kutentha chomwe dzina lake lonse ndi disodium ethylenediamine tetraacetate. Ndi ufa wopanda hygroscopic womwe ndi wopanda mtundu, wopanda fungo, komanso wopanda kukoma pamlingo woyenera wogwiritsidwa ntchito. Mankhwala a 1% ali ndi pH ya 4.3–4.7. Amagwiritsidwa ntchito polamulira momwe zitsulo zocheperako zimagwirira ntchito kuti ziphatikizepo calcium ndi magnesium ndi zinthu zina zachilengedwe ndi zosapangidwa m'zakudya kuti apewe kuwonongeka kwa mtundu, kapangidwe, ndi kukula kwa ma precipitates komanso kupewa okosijeni. Ntchito yake ndi yofanana ndi ya disodium calcium edta.
