EDTA-ACID Cov
EDTA acid (ethylenediamine tetraacetic acid, Ethylenediaminetetraacetic acid) yog ib qho khoom siv chelate, nws daim ntawv lub cev raws li hauv qab no:
Cov mis mos molecular: C₁₀H₁₆N₂O₈
Molecular Luj: 292.24 g / mol
Cov tsos mob: Ntshiab EDTA acid feem ntau yog dawb crystalline hmoov.
Solubility nyob rau hauv dej: me ntsis yaj, solubility ntawm 20 degree yog hais txog 0.5 g / L.
Solubility nyob rau hauv acid thiab alkali daws yog zoo dua, tshwj xeeb tshaj yog nyob rau hauv alkaline daws solubility yog ho txhim kho.
Insoluble hauv cov kuab tshuaj organic xws li ethanol thiab ether.
Melting point: kwv yees li 240 degree (decomposition).
Nyob ruaj khov ntawm chav tsev kub thiab siab, tab sis rhiab rau cov dej noo, yooj yim rau nqus noo noo.
Nws yog qhov ruaj khov rau lub teeb thiab cua sov, tab sis tuaj yeem decompose rau hauv cov pa phem xws li carbon monoxide, carbon dioxide thiab nitrogen oxides ntawm qhov kub thiab txias.
Lub pH ntawm nws cov kua aqueous yog acidic, tab sis tus nqi tshwj xeeb nyob ntawm qhov solubility thiab concentration.
Qhov ceev: kwv yees li 0 86 g/cm³ (20 degree ).

Ethylenediamine tetraacetic acid (EDTA) yog ib qho tseem ceeb chelating tus neeg sawv cev, uas tuaj yeem tsim cov dej-soluble complexes ruaj khov nrog ntau yam hlau ions. Cov yam ntxwv no ua rau nws muaj peev xwm siv dav hauv ntau lub teb.Nyob rau hauv kev ua liaj ua teb, nws yog dav siv nyob rau hauv kev npaj cov kab kawm chiv. Los ntawm kev siv tshuab chelating, nws tuaj yeem txhim kho cov solubility thiab nqus ntawm cov kab mob, thiab txhawb kev loj hlob thiab kev loj hlob ntawm cov nroj tsuag. Tsis tas li ntawd, nws tuaj yeem siv los txhim kho cov av ib puag ncig thiab pab cov nroj tsuag nqus cov as-ham zoo dua. Tsis tas li ntawd, nws yog siv rau hauv kev npaj ntawm qee yam tshuaj formulations los txhim kho kev ruaj ntseg thiab bioavailability ntawm cov tshuaj.In cov tshuaj pleev ib ce kev lag luam, nws yog ntxiv rau. ntau yam khoom tu tawv nqaij thiab tshuaj zawv plaub hau ua tus neeg sawv cev chelate rau chelate hlau ions hauv dej thiab tiv thaiv cov hlau ions los ntawm kev cuam tshuam tsis zoo nrog lwm cov khoom xyaw hauv cov khoom, yog li ncua lub txee lub neej ntawm cov khoom thiab tswj nws cov txiaj ntsig.
