Oxalic Acid

Cov lus piav qhia luv luv:

Yog hom organic acid, yog cov khoom lag luam metabolic ntawm cov muaj sia, cov tsiaj roj ntsha, thiab cov tsiaj txhu thiab cov tsiaj muaj sia ua si sib txawv. Nws tau pom tias oxalic acid nplua nuj nyob rau ntau tshaj 100 hom nroj tsuag, tshwj xeeb yog zaub ntsuab, amaranth, beet, taro, qos yaj ywm, qab zib, qab zib, qab zib, qab zib, qab zib, qab zib, qab zib, qos yaj ywm thiab rhubarb. Vim tias oxalic acid tuaj yeem txo cov xyoob ntawm cov pob zeb hauv av, nws tau suav hais tias yog kev tawm tsam rau kev nqus cov ntxhia. Nws anhydride yog carbon sesquioxide.

Oxalic acid yog cov kua qaub tsis muaj zog. Thawj-txiav txim one1 = 5.9 × 10-2 thiab qhov thib ob-xaj one) = 6.4 × 10-5. Nws muaj acid accural. Nws tuaj yeem nruab siab lub hauv paus, discolor qhov ntsuas, thiab tso cov pa roj carbon dioxide los ntawm kev sib cuam tshuam nrog cov pa roj carbonates. Nws muaj kev sib txig sib txig thiab yog qhov yooj yim kom ua oxidized rau hauv cov pa roj carbon dioxide thiab dej los ntawm oxidizing tus neeg sawv cev. Accidanassium permanganate (kmno4) kev daws teeb meem tuaj yeem raug tshem tawm thiab txo qis rau 2-muaj kev sib tw manganese ion.

Dyeing Adinitive

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

Ntxuav

Daim ntawv thov ntawm Zesolite raws li cov tub lim hauv cov ntawv kev lag luam tuaj yeem txhim kho kev ua tau zoo, yog li ntawd nws qhov kev ua tau zoo, nws yog qhov ua tau zoo dua, thiab nws muaj qee qhov hluav taws kub tiv thaiv.

Plastics Kev Lag Luam

Plastics kev lag luam rau kev tsim cov polyvinyl chloride, amino plastics, urea formaldehyde plastics, pleev xim duab thiab lwm yam.

Photovoltaic kev lag luam

Oxalic acid kuj tseem siv nyob rau hauv kev lag luam photovoltaic. Oxalic acid tuaj yeem siv los ua kom cov khoom ua si silicon wafers rau cov khoom siv hnub ci, pab kom txo qhov tsis xws luag nyob ntawm qhov chaw ntawm cov 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 catalyst rau phenolic resin synthesis, cov txheej txheem catalytic yog qhov sib zog me, cov txheej txheem tsis ruaj khov, thiab lub sijhawm ntev tshaj plaws. Acetone Oxalate daws tau cathening cov tshuaj tiv thaiv ntawm epoxy cob qhia thiab luv luv lub sijhawm kho. Nws kuj tseem siv tau ua cov xov tooj ntawm PHEM RAU COV SCHTHesis ntawm Urea-Formaldehyde Resin thiab Melamine Formalrehyde Resin. Nws kuj tseem tuaj yeem raug ntxiv rau dej-soluble polyvinyl cawv nplaum kom txhim kho kev ziab nrawm nrawm nrawm nrawm nrawm nrawm. Nws kuj tseem siv tau los ua tus saib xyuas tus neeg sawv cev ntawm urea-formaldehyde cob thiab hlau ion chelating tus neeg sawv cev. Nws tuaj yeem siv los ua tus nrawm los npaj cov hmoov txhuv nplej siab nrog Kmno4 oxidizing tus neeg sawv cev los ua kom cov oxidation ceev thiab lub sijhawm luv.
