Oxalic Acid

piav qhia luv luv:

Nws yog ib hom organic acid, yog ib yam khoom ntawm cov kab mob metabolic, binary acid, dav faib nyob rau hauv cov nroj tsuag, tsiaj txhu thiab fungi, thiab nyob rau hauv cov kab mob sib txawv ua si sib txawv.Nws tau pom tias oxalic acid yog nplua nuj nyob rau hauv ntau tshaj 100 hom nroj tsuag, tshwj xeeb tshaj yog spinach, amaranth, beet, purslane, taro, qos yaj ywm qab zib thiab rhubarb.Vim tias oxalic acid tuaj yeem txo qhov bioavailability ntawm cov ntxhia hauv cov ntsiab lus, nws raug suav tias yog ib qho antagonist rau kev nqus thiab siv cov ntxhia hauv cov ntsiab lus.Nws cov anhydride yog carbon sesquioxide.

Khoom siv

Dyeing additive

Hauv kev lag luam luam ntawv thiab dyeing, nws tuaj yeem hloov acetic acid los ua thawj xim.Siv raws li cov xim thiab tshuaj dawb rau cov xim dyes.Nws tuaj yeem ua ke nrog qee yam tshuaj los tsim cov dyes, thiab tseem tuaj yeem siv los ua tus stabilizer rau dyes, yog li ncua lub neej ntawm dyes.

Cleanser

Daim ntawv thov ntawm zeolite ua muab tub lim rau hauv daim ntawv kev lag luam tuaj yeem txhim kho kev ua haujlwm thiab cov ntawv zoo, kom nws cov porosity nce, kev nqus dej tau zoo dua qub, nws yooj yim dua rau kev txiav, kev sau ntawv tau zoo dua, thiab nws muaj qee yam hluav taws kub.

Kev lag luam yas

Plastics kev lag luam rau zus tau tej cov polyvinyl chloride, amino plastics, urea formaldehyde plastics, xim chips thiab hais txog.

Kev lag luam photovoltaic

Oxalic acid kuj tseem siv rau hauv kev lag luam photovoltaic.Oxalic acid tuaj yeem siv los ua silicon wafers rau hnub ci vaj huam sib luag, pab txo qhov tsis xws luag ntawm silicon wafers.

Xuab zeb ntxuav

Oxalic acid ua ke nrog hydrochloric acid thiab hydrofluoric acid tuaj yeem ua rau cov kua qaub ntxuav ntawm quartz xuab zeb.

Synthesis catalyst

Raws li ib qho catalyst rau phenolic resin synthesis, cov tshuaj tiv thaiv catalytic yog me me, cov txheej txheem kuj ruaj khov, thiab lub sijhawm ntev tshaj plaws.Cov tshuaj Acetone oxalate tuaj yeem ua rau cov tshuaj tiv thaiv kho ntawm epoxy resin thiab ua kom lub sijhawm kho.Nws kuj yog siv los ua pH regulator rau cov synthesis ntawm urea-formaldehyde resin thiab melamine formaldehyde resin.Nws tseem tuaj yeem muab ntxiv rau cov dej-soluble polyvinyl cawv nplaum los txhim kho qhov ziab kom nrawm thiab kev sib khi lub zog.Nws kuj tseem siv tau los ua tus neeg sawv cev kho ntawm urea-formaldehyde resin thiab hlau ion chelating tus neeg sawv cev.Nws tuaj yeem siv los ua tus accelerator los npaj cov hmoov txhuv nplej siab nrog KMnO4 oxidizing tus neeg saib xyuas kom ceev oxidation tus nqi thiab txo lub sij hawm cov tshuaj tiv thaiv.
