Chaw tsim tshuaj paus cov nqe lag luam zoo nkauj oxalic acid CAS: 144-62-7

Cov lus piav qhia luv luv:

Oxalic acid yog ib qho muaj zog dicarboxylic kua qaub tshwm sim nyob rau hauv ntau cov nroj tsuag thiab zaub, feem ntau yog nws cov calcium lossis cov ntsev potassium. Oxalic acid yog qhov tsuas ua tau compound nyob rau hauv uas ob pawg carboxyl tau koom ncaj qha; Vim li no oxalic acid yog ib qho ntawm cov organic muaj zog tshaj plaws. Tsis zoo li lwm cov roj carboxylic acids (tsuas yog formic acid), nws yog qhov yooj yim oxidized; Qhov no ua rau nws muaj txiaj ntsig zoo li tus neeg sawv cev txo tus neeg sawv cev rau kev thaij duab, tshuaj dawb, thiab tus cwj mem raug tshem tawm. Oxalic acid feem ntau yog npaj los ntawm cov cua sov sodium decate ua cov sodium oxaleate thiab kho nrog cov sulfuric acid kom tau txais oxalic acid kom tau dawb oxalic acid.
Kev ua tau zoo ntawm oxalic acid tau zoo nkauj qis nyob rau hauv feem ntau cov nroj tsuag thiab nroj tsuag thiab beet zaub ntsuab los cuam tshuam nrog kev nqus cov calcium cov nroj tsuag kuj muaj.
Nws yog tsim nyob rau hauv lub cev los ntawm metabolism ntawm glyoxylic acid los yog ascorbic acid. Nws tsis yog metabolized tab sis tawm hauv cov zis. Nws yog siv los ua kev tshuaj ntsuam thiab dav dav txo cov neeg saib xyuas tus neeg saib xyuas.Oxalic acid yog ib lub ntuj mites nyob rau hauv cov kob nrog tsis muaj / tus brood, pob, lossis cov pob zeb. Vaporized oxalic acid yog siv los ntawm qee cov beekeepers raws li ib tug kab tshuaj tua kab rau ntawm parasitic varroa mite.

Tshuaj lom neeg cov khoom:Oxalic acid yog cov hmoov tsis muaj kob, tsw ntxhiab, lossis cov khoom ci. Daim ntawv anhydrous (COH) 2 yog qhov tsis muaj ntxhiab, cov khoom dawb; Qhov kev daws teeb meem yog cov kua tsis muaj kob.

Cov ntawv thov ntawm oxalic acid

1. Oxalic acid tuaj yeem siv los ua txo tus neeg sawv cev thiab tshuaj dawb rau zas xim, cov ntaub ntawv ntawm ntau sab, oxalate thiab lwm yam.

2. Siv los ua kev ntsuas cov tshuaj reagent.

3. Siv raws li kev kuaj qab zib reagents, chromatography tsom xam reagent, zas xim thiab cov khoom siv.

4. Oxalic acid yog siv rau kev tsim cov tshuaj xws li tshuaj tua kab mob thiab cov neeg muaj kuab lom thiab zas xim thiab zas xim thiab zas xim thiab zas xim rau cov tshuaj oxalis Ester, oxalate, thiab oxamide nrog diethyl oxalate, sodium oxalate thiab calcium oxalate muaj cov txiaj ntsig loj tshaj plaws. Oxalate kuj tseem siv tau rau kev tsim cov cobalt-Molybdenum-alumina catalyst, kev tu ntawm hlau thiab marble raws li cov tshuaj pleev ntawm textiles.

Kev ua liaj ua teb siv:Oxalic acid, (COH) 2, tseem hu ua Ethanedioic acid, yog khoom dawb, crystalline khoom, me ntsis soluble hauv dej. Nws yog ib qho tshwm sim zoo heev oxidized organic compound nrog cov kev ua si chelating tseem ceeb. Nws yog qhov muaj zog acidic thiab lom, tsim los ntawm ntau cov nroj tsuag zoo li sorrel (sourwood), cov nplooj ntoos hlav ntawm rhubarb, tawv ntoo ntawm eucalyptus thiab ntau tsob ntoo keeb kwm. Hauv cov nroj tsuag thiab cov ntaub so ntswg, oxalic acid tau ntau dua li sodium, potassium lossis calcium oxalate, ntawm qhov kawg tshwm sim yog muaju. Nyob rau hauv lem, ntsev ntawm oxalic acids sau rau hauv lub cev ntawm cov tsiaj thiab tib neeg quavntsej, ua rau pathologrers, nyob ntawm seb cov nyiaj noj haus. Ntau hom kev lom zem ntawm Fungi zoo li Aspergillus, penicillium, mucor, nrog rau qee cov ntaub pwm thiab cov pwm ua pwm tuaj yeem tsim cov calcium oxalate muaju caldium. Thaum muaj kev tuag ntawm cov kab mob me, nroj tsuag thiab tsiaj, cov ntsev ua kua tau tso rau hauv av, ua rau qee qhov hnoos qeev. Txawm li cas los xij, oxalate-degrading microbes, hu ua Oxalobacter ntawv, txo cov oxalate nqus tub rog thiab tib neeg.

Oxalic acid yog thawj ntawm cov series ntawm dicarboxylic acids. Nws yog siv (a) raws li tus neeg sawv cev rau cov stains zoo li xeb thiab tawv, thiab tawv ntau lawm, thiab (c) ua cov dej cawv ntawm cov ally1 Cawv thiab cov kua qaub acid.
