ACIDIQUE

Acide ya Oxalicni ibintu kama.Imiterere yimiti ni H₂C₂O₄.Nibicuruzwa biva mu binyabuzima.Nibice bibiri bigize aside idakomeye.Ikwirakwizwa cyane mu bimera, inyamaswa, n’ibihumyo.Ikora imirimo itandukanye mubinyabuzima bitandukanye.Kubwibyo rero, aside ya oxyde ikunze gufatwa nkurwanya kurwanya no gukoresha ibintu byamabuye y'agaciro.Anhydride yayo ni karubone trioxide.

Ibiranga:Urupapuro rwa monoclinic rutagira ibara cyangwa prismatic kristal cyangwa ifu yera, aside ya oxyde itagira impumuro nziza ya okiside, aside aside ya oxyde na synthesis.Sublimation kuri 150 ~ 160 ℃.Irashobora kuba ikirere cyumuyaga ushushe.1g irashonga mumazi 7mL, 2mL amazi abira, 2,5mL Ethanol, 1.8mL itetse Ethanol, 100mL ether, 5.5mL glycerine, hamwe no kudashonga muri benzene, chloroform na peteroli.0.1mol / L igisubizo gifite pH ya 1.3.Ubucucike bugereranije (amazi = 1) ni 1.653.Gushonga ingingo 189.5 ℃.

Ibikoresho bya shimi:Acide Oxalic, izwi kandi nka acide glycolike, iboneka cyane mu biribwa by'ibimera.Acide Oxalic ni inkingi itagira ibara ya kirisiti, ishonga mumazi aho kuba mumashanyarazi nka ether,

Oxalate igira ingaruka zikomeye zo guhuza kandi nubundi bwoko bwicyuma gikonjesha ibiryo byibimera.Iyo aside ya oxyde ihujwe nibintu bimwe na bimwe bya alkaline yisi, ibyuma byayo biragabanuka cyane, nka calcium oxyde ya calcium iba idashonga mumazi.Kubwibyo, kuba aside ya oxyde ifite ingaruka zikomeye kuri bioavailable ya minerval yingenzi;Iyo aside ya oxalic ihujwe nibintu bimwe byinzibacyuho byinzibacyuho, ibimera bigenda byangirika bitewe nigikorwa cyo guhuza aside aside, kandi imbaraga zayo ziyongera cyane.

Acide Oxalic yatangiye kugabanuka kuri 100 ℃, igabanuka vuba kuri 125 and, kandi igabanuka cyane kuri 157 and, itangira kubora.

Irashobora kwitwara hamwe na alkali, irashobora kubyara esterification, acyl halogenation, amide reaction.Kugabanya reaction birashobora kandi kubaho, kandi decarboxylation reaction irashobora kubaho munsi yubushyuhe.Anhydrous oxalic aside ni hygroscopique.Acide ya Oxalic ikora amazi-ashonga hamwe nibyuma byinshi.

Ibisanzwe bisanzwe:1, Sodium oxalate; 2, Potasiyumu oxalate; 3, Kalisiyumu ya Kalisiyumu; 4, Ferrous oxalate;5, Antimony oxalate;6, Ammonium hydrogen oxyde;7, Magnesium oxalate 8, Litiyumu.

Gusaba:

1. Umukozi ugoye, umukozi wa mask, umukozi wimvura, kugabanya umukozi.Ikoreshwa mukumenya beryllium, calcium, chromium, zahabu, manganese, strontium, thorium nibindi byuma bya ion.Isesengura rya Picocrystal kuri sodium nibindi bintu.Kugabanya calcium, magnesium, thorium nibintu bidasanzwe byisi.Igisubizo gisanzwe cyo guhinduranya potasiyumu permanganate hamwe nibisubizo bya sulfate.Bleach.Imfashanyo.Irashobora kandi gukoreshwa mu gukuraho ingese ku myenda mu nganda zubaka mbere yo koza urukuta rw'inyuma, kubera ko urukuta rwa alkaline rukomeye rugomba kubanza gukaraba aside alkalike.

2. Inganda zimiti zikoreshwa mugukora aureomycine, oxytetracycline, streptomycine, borneol, vitamine B12, phenobarbital nindi miti.Inganda zo gucapa no gusiga amarangi zikoreshwa nkimfashanyo yamabara, byakuya, ubuvuzi hagati.Inganda za plastiki zo gukora PVC, plastike ya amino, urea - plastike ya fordehide.

3. Byakoreshejwe nk'umusemburo wa fenolike resin synthesis, reaction ya catalitike iroroshye, inzira irahagaze neza, kandi igihe ni kirekire.Umuti wa Acetone oxalate urashobora guhagarika gukira kwa epoxy resin no kugabanya igihe cyo gukira.Ikoreshwa kandi nka syntetique urea formaldehyde resin, melamine formaldehyde resin pH igenzura.Irashobora kandi kwongerwaho muri polyvinyl formaldehyde yamazi yangirika kugirango yongere umuvuduko wumye hamwe nimbaraga zo guhuza.Ikoreshwa kandi nka urea formaldehyde resin ikiza, icyuma cya ion chelating agent.Irashobora gukoreshwa nkihuta mugutegura ibishishwa bya krahisi hamwe na okiside ya KMnO4 kugirango byihute umuvuduko wa okiside kandi bigabanye igihe cyo kubyitwaramo.

Nkumukozi wo guhumanya:

Acide ya Oxalic ikoreshwa cyane cyane nko kugabanya imiti na bleach, ikoreshwa mugukora antibiyotike na borneol hamwe nindi miti, ndetse no gutunganya ibyuma bidasanzwe, ibishishwa bigabanya amarangi, ibikoresho byo gutwika, nibindi.

Acide ya Oxalic irashobora kandi gukoreshwa mugukora cobalt-molybdenum-aluminiyumu, gusukura ibyuma na marble, no guhumanya imyenda.

Ikoreshwa mugusukura ibyuma no kuvura, gukuramo ibintu bidasanzwe kwisi, gucapa imyenda no gusiga irangi, gutunganya uruhu, gutegura catalizator, nibindi.

Nkumukozi ugabanya:

Mu nganda ngengabihe ikoreshwa cyane cyane mu gukora hydroquinone, pentaerythritol, cobalt oxalate, nikel oxalate, aside gallic nibindi bicuruzwa bivura imiti.

Inganda za plastiki zo gukora PVC, plastike ya amino, urea - plastike ya formaldehyde, amarangi, nibindi.

Inganda zisiga irangi zikoreshwa mugukora icyatsi kibisi nibindi.

Inganda zo gucapa no gusiga irangi zirashobora gusimbuza acide acetike, ikoreshwa nkibara ryamabara ya pigment, ibara ryangiza.

Inganda zimiti yo gukora aureomycine, tetracycline, streptomycine, ephedrine.

Byongeye kandi, aside ya oxyde irashobora kandi gukoreshwa muguhuza ibinyabuzima bitandukanye bya oxalate, oxalate na oxalamide, hamwe na diethyl oxalate, sodium oxalate, calcium oxalate nibindi bicuruzwa bitanga umusaruro mwinshi.

Uburyo bwo kubika:

1. Funga ahantu humye kandi hakonje.Kurinda cyane amazi, kutagira amazi nizuba.Ubushyuhe bwo kubika ntibugomba kurenga 40 ℃.

2. Irinde okiside nibintu bya alkaline.Koresha imifuka ya polypropilene ikozwe mumifuka ya plastike, 25kg / umufuka.

Muri rusange, aside ya oxyde ni imiti itandukanye hamwe nibikorwa byinshi mubikorwa bitandukanye.Imiterere yacyo ituma ihitamo ryiza ryo gukora isuku, gutunganya no guhumanya, kandi ifite porogaramu nyinshi mubikorwa byimyenda, ubusitani nubukorikori.Nyamara, ingamba z'umutekano zigomba gufatwa mugihe ukoresheje iyi miti, kuko ari uburozi kandi irashobora kwangiza iyo idakozwe neza.
