Chaw tsim tshuaj paus Zoo Nqe Oxalic Acid CAS: 144-62-7

1. Oxalic acid tuaj yeem siv tau los ua tus neeg saib xyuas kom txo qis thiab tshuaj dawb, mordant rau dyeing thiab luam ntawv kev lag luam, kuj siv rau hauv refining tsawg hlau, cov synthesis ntawm ntau yam oxalate ester amide, oxalate thiab nyom, thiab lwm yam.

2. Siv ua analytical reagent.

3. Siv raws li kev kuaj reagents, chromatography tsom xam reagent, dye intermediates thiab cov khoom txheem.

4. Oxalic acid feem ntau yog siv los tsim cov tshuaj xws li tshuaj tua kab mob thiab borneol thiab hnyav rau rho tawm cov hlau tsis tshua muaj, txo tus neeg sawv cev thiab dye, tanning tus neeg saib xyuas, thiab lwm yam. Tsis tas li ntawd, oxalic acid kuj tseem siv tau rau kev sib txuas ntawm ntau yam oxalate. ester, oxalate, thiab oxamide nrog diethyl oxalate, sodium oxalate thiab calcium oxalate muaj cov txiaj ntsig loj tshaj plaws.Oxalate tseem tuaj yeem siv rau kev tsim cov cobalt-molybdenum-alumina catalyst, ntxuav cov hlau thiab marble nrog rau cov tshuaj dawb ntawm textiles.

Agricultural Siv:Oxalic acid, (COOH)2, tseem hu ua ethanedioic acid, yog dawb, crystalline khoom, me ntsis soluble hauv dej.Nws yog ib qho tshwm sim tshwm sim heev oxidized organic compound nrog chelates tseem ceeb.Nws yog acidic thiab lom, tsim los ntawm ntau cov nroj tsuag xws li sorrel (sourwood), nplooj nplooj ntawm rhubarb, bark ntawm eucalyptus thiab ntau cov hauv paus hniav.Nyob rau hauv cov nroj tsuag thiab cov ntaub so ntswg, oxalic acid tau txais los ntawm sodium, potassium los yog calcium oxalate, uas tom kawg tshwm sim li crystals.Nyob rau hauv lem, ntsev ntawm oxalic acids nkag mus rau hauv lub cev ntawm cov tsiaj thiab tib neeg beings, ua rau pathological mob, nyob ntawm seb tus npaum li cas noj.Ntau hom fungi zoo li Aspergillus, Penicillium, Mucor, nrog rau qee cov lichens thiab slime pwm tsim calcium oxalate crystals.Thaum tuag ntawm cov kab mob no, cov nroj tsuag thiab tsiaj txhu, cov ntsev tau tso rau hauv cov av, ua rau qee qhov muaj kuab lom.Txawm li cas los xij, oxalate-degrading microbes, hu ua Oxalobacter formigenes, txo oxalate nqus hauv cov tsiaj thiab tib neeg.

Oxalic acid yog thawj zaug ntawm cov tshuaj dicarboxylic acids.Nws yog siv (a) ua cov tshuaj bleaching rau stains xws li xeb los yog number case, (b) nyob rau hauv textile thiab tawv ntau lawm, thiab (c) raws li monoglyceryl oxalate nyob rau hauv zus tau tej cov ally1 cawv thiab formic acid.
