EDTA-ACID Cov

EDTA Acid, tseem hu ua Ethylene Diamine Tetraacetic Acid, yog ib qho tseem ceeb organic compound nrog daim ntawv C₁₀H₁₆N₂O₈. Nws yog cov khoom tsis muaj xim, tsis muaj ntxhiab tsw uas yaj hauv dej thiab feem ntau siv rau hauv kev tshuaj xyuas tshuaj thiab kev siv hauv kev lag luam.

Chemical Properties:
Cov mis mos molecular: C₁₀H₁₆N₂O₈
Molar hnyav: 292.24 g / mol
Structure: nws cov molecule muaj ob pawg amino (-NH₂) thiab plaub pawg carboxylic (-COOH), uas tuaj yeem tsim kev sib koom tes ruaj khov nrog ntau yam hlau ions.

kev npaj: nws feem ntau yog npaj los ntawm cov tshuaj tiv thaiv ntawm cyanacetic acid nrog ethylenediamine. Cov kauj ruam tshwj xeeb yog raws li nram no:

Ethylenediamine reacts nrog cyanoacetate nyob rau hauv cov xwm txheej yooj yim los ua N, N'-bis (carboxymethyl) ethylenediamine.
Lub intermediate ces underwed ib tug ntxiv tshuaj tiv thaiv los tsim nws.

Nws yog polyvalent chelator muaj peev xwm tsim tau ib qho ruaj khov chelate nrog ntau cov divalent thiab trivalent hlau ions (xws li Ca² +, Mg² +, Fe³ +, thiab lwm yam) thiab feem ntau yog siv rau hauv kev sib cais thiab kev soj ntsuam ntawm softened dej thiab hlau ions.

Hauv kev kho dej, EDTA feem ntau yog siv rau cov dej softening thiab tshem tawm cov hlau hnyav ions. Los ntawm chelating, EDTA tuaj yeem ntes thiab tshem tawm cov tawv tawv ions xws li calcium thiab magnesium los ntawm dej, tiv thaiv cov ions los ntawm kev tsim cov nplai hauv cov kav dej thiab cov boilers. Qhov kev ua haujlwm no yog qhov tseem ceeb rau ob qho tib si kev lag luam thiab kev siv dej hauv tsev, vim qhov ntsuas tsis tau tsuas yog txo cov khoom siv, tab sis kuj tuaj yeem ua rau cov khoom puas tsuaj. Tsis tas li ntawd, EDTA tuaj yeem tshem tawm cov hlau hnyav xws li txhuas, cadmium thiab mercury los ntawm dej, ua kom muaj kev nyab xeeb ntawm cov dej zoo.

Ua tsaug rau koj tuaj xyuas thiab txais tos koj cov lus nug zoo!
