Chaw Tsim Khoom Zoo Nqe Oxalic Acid CAS: 144-62-7

1. Oxalic acid feem ntau siv los ua tus neeg sawv cev txo qis thiab tus neeg sawv cev dawb, mordant rau kev lag luam dyeing thiab luam ntawv, kuj siv rau hauv kev ua kom cov hlau tsis tshua muaj, kev tsim cov oxalate ester amide, oxalate thiab nyom, thiab lwm yam.

2. Siv ua cov tshuaj reagent analytical.

3. Siv ua cov tshuaj reagents hauv chaw kuaj mob, cov tshuaj chromatography analysis, cov xim nruab nrab thiab cov khoom siv txheem.

4. Oxalic acid feem ntau yog siv los tsim cov tshuaj xws li tshuaj tua kab mob thiab borneol thiab cov kuab tshuaj rau kev rho tawm cov hlau tsis tshua muaj, cov neeg sawv cev txo qis thiab cov xim zas, cov neeg sawv cev tanning, thiab lwm yam. Tsis tas li ntawd, oxalic acid kuj tseem siv tau rau kev tsim ntau yam oxalate ester, oxalate, thiab oxamide nrog diethyl oxalate, sodium oxalate thiab calcium oxalate uas muaj cov txiaj ntsig loj tshaj plaws. Oxalate kuj tseem siv tau rau kev tsim cov cobalt-molybdenum-alumina catalyst, ntxuav cov hlau thiab marble nrog rau kev ua kom cov ntaub dawb.

Kev Siv Ua Liaj Ua Teb:Oxalic acid, (COOH)2, tseem hu ua ethanedioic acid, yog ib yam khoom dawb, crystalline khov, me ntsis soluble hauv dej. Nws yog ib qho organic compound uas tshwm sim los ntawm ntuj tsim uas muaj oxidized heev nrog rau kev ua haujlwm chelating tseem ceeb. Nws yog acidic heev thiab lom, tsim los ntawm ntau cov nroj tsuag xws li sorrel (sourwood), cov nplooj ntawm rhubarb, tawv ntawm eucalyptus thiab ntau cov hauv paus ntawm cov nroj tsuag. Hauv cov hlwb thiab cov ntaub so ntswg ntawm cov nroj tsuag, oxalic acid tau sau ua sodium, potassium lossis calcium oxalate, uas qhov tom kawg tshwm sim ua cov siv lead ua. Nyob rau hauv lem, ntsev ntawm oxalic acids nkag mus rau hauv lub cev ntawm cov tsiaj txhu thiab tib neeg, ua rau muaj kev mob nkeeg, nyob ntawm seb noj ntau npaum li cas. Ntau hom fungi xws li Aspergillus, Penicillium, Mucor, nrog rau qee cov lichens thiab slime pwm tsim cov calcium oxalate siv lead ua. Thaum cov kab mob me me, cov nroj tsuag thiab tsiaj txhu tuag, cov ntsev tau tso tawm rau hauv av, ua rau muaj qee qhov kev lom. Txawm li cas los xij, cov kab mob oxalate-degrading, hu ua Oxalobacter formigenes, txo qis kev nqus oxalate hauv cov tsiaj txhu thiab tib neeg.

Oxalic acid yog thawj zaug ntawm cov dicarboxylic acids. Nws yog siv (a) ua tus neeg sawv cev rau cov xim xws li xeb lossis kua mem, (b) hauv kev tsim cov ntaub thiab tawv, thiab (c) ua monoglyceryl oxalate hauv kev tsim cov cawv ally1 thiab formic acid.
