Oxalic acid yog cov khoom siv organic nrog cov tshuaj formula H₂C₂O₄.Nws yog ib qho metabolite ntawm cov kab mob nyob.Nws yog dibasic tsis muaj zog acid.Nws yog dav faib nyob rau hauv cov nroj tsuag, tsiaj txhu thiab fungi, thiab plays txawv functions nyob rau hauv ntau yam kab mob.Nws cov kua qaub anhydride yog carbon trioxide.Cov tsos ntawm oxalic acid yog xim tsis muaj xim monoclinic flake los yog prismatic siv lead ua los yog hmoov dawb, tsw, qaub saj, yooj yim soluble hauv dej tab sis tsis soluble hauv organic solvents xws li ether.Qhov hnyav molecular ntawm oxalic acid yog 90.0349.
Kev siv oxalic acid: complexing agent, masking agent, precipitating agent, reduce agent.
1, raws li cov tshuaj bleaching
Oxalic acid feem ntau yog siv los txo tus neeg sawv cev thiab tshuaj dawb, siv hauv kev tsim cov tshuaj xws li tshuaj tua kab mob thiab borneol, ua cov kuab tshuaj rau kev rho tawm ntawm cov hlau tsis tshua muaj, ua cov tshuaj tua kab mob, thiab ua tus neeg sawv cev tanning.
Oxalic acid kuj tseem siv rau hauv kev tsim cov cobalt-molybdenum-aluminium catalysts, ntxuav cov hlau thiab marble, thiab bleaching ntawm textiles.
2. Raws li tus neeg sawv cev txo qis
Hauv kev lag luam organic synthesis, nws yog siv los tsim cov khoom siv tshuaj xws li hydroquinone, pentaerythritol, cobalt oxalate, nickel oxalate, thiab gallic acid.
Kev lag luam yas yog siv rau hauv kev tsim cov polyvinyl chloride, aminoplastics, urea-formaldehyde plastics, lacquer nplooj, thiab lwm yam.
Kev lag luam dyeing yog siv los tsim cov ntsev-raws li magenta ntsuab, thiab lwm yam.
Hauv kev lag luam luam ntawv thiab dyeing, nws tuaj yeem hloov acetic acid thiab siv los ua xim tsim kev pab thiab tshuaj dawb rau cov xim xim.
Kev lag luam kws tshuaj yog siv rau hauv kev tsim cov chlortetracycline, oxytetracycline, tetracycline, streptomycin, thiab ephedrine.
Tsis tas li ntawd, oxalic acid kuj tuaj yeem siv los ua ke ntau yam khoom xws li oxalate, oxalate thiab oxalamide, ntawm cov khoom siv diethyl oxalate, sodium oxalate thiab calcium oxalate yog cov khoom tsim tau tshaj plaws.
3. Raws li ib tug mordant
Antimony oxalate tuaj yeem siv los ua mordant, thiab ferric ammonium oxalate yog tus neeg sawv cev rau kev luam ntawv
4 Kev tshem tawm xeb ua haujlwm
Oxalic acid tuaj yeem siv los tshem tawm cov xeb: yuav ib lub raj mis ntawm oxalic acid los ntawm lub khw muag tshuaj chemical reagents, coj ib co, ua ib qho kev daws nrog dej sov, siv rau cov xeb thiab so nws.(Ceeb toom: Ceev faj thaum siv, oxalic acid yog corrosive heev rau stainless hlau, oxalic acid nrog siab concentration kuj yog ib qho yooj yim rau corrode tes. Thiab cov kua qaub oxalate generated yog heev soluble, tab sis muaj ib co degree ntawm toxicity. Tsis txhob noj nws. Thaum siv . Tom qab daim tawv nqaij los rau hauv kev sib cuag nrog oxalic acid, nws yuav tsum tau ntxuav nrog dej raws sij hawm.)
Oxalic acid cia khoom
1. Khaws rau hauv qhov chaw qhuav thiab txias.nruj me ntsis noo-pov thawj, waterproof, tshuaj pleev thaiv hnub.Cia kub yuav tsum tsis pub tshaj 40 ℃.
2. Khaws kom deb ntawm cov oxides thiab alkaline.Ntim hauv polypropylene woven hnab lined nrog lub hnab yas.
