Disodium EDTA CAS: 139-33-3 Chaw Tsim Khoom

EDTA disodium, tseem hu ua Disodium edetate dihydrate, yog ib qho tshuaj zoo hauv kev sib koom tes hauv chemistry. Nws muaj rau lub atoms sib koom tes, thiab cov complex tsim hu ua chelate. EDTA feem ntau siv rau hauv kev sib koom tes titration, thiab nws feem ntau siv los txiav txim siab cov ntsiab lus ntawm cov hlau ions. EDTA disodium yog ib hom khoom noj khoom haus additive tso cai los ntawm GB2760, uas tuaj yeem tiv thaiv lossis ncua qhov discoloration, oxidation, rancidity, thiab lwm yam. Ethylenediaminetetraacetic acid disodium ntsev yog siv dav hauv kev lag luam textile. Feem ntau siv los yaj limescale. Nws yog siv rau hauv kev lag luam textile, pulp thiab ntawv kev lag luam thiab tseem nyob rau hauv chelation therapy. Hauv kev kho kom zoo nkauj, nws ua haujlwm ua tus neeg sawv cev sequestering. Nws ua haujlwm ua tus neeg tiv thaiv corrosion rau carbon hlau hauv kev lag luam. Nws kuj ua haujlwm ua tus neeg ntxiv khoom noj khoom haus. Disodium Dihydrogen EDTA yog ib qho sequestrant thiab chelating agent uas nws lub npe tag nrho yog disodium ethylenediamine tetraacetate. nws yog ib qho hmoov tsis hygroscopic uas tsis muaj xim, tsis muaj ntxhiab, thiab tsis saj ntawm cov qib pom zoo siv. Ib qho tshuaj 1% muaj ph ntawm 4.3–4.7. Nws yog siv los tswj cov tshuaj tiv thaiv ntawm cov hlau me me kom suav nrog calcium thiab magnesium nrog lwm cov khoom organic thiab inorganic hauv cov zaub mov kom tiv thaiv kev puas tsuaj ntawm cov xim, kev ntxhib los mos, thiab kev loj hlob ntawm cov av noo thiab tiv thaiv kev oxidation. Nws txoj haujlwm zoo ib yam li disodium calcium edta.
