Acide ya oxalic

Acide ya oxalicni ibintu kama. Imiterere yimiti ni H₂c₂o₄. Nibicuruzwa bya metabolike yibinyabuzima. Nibice bibiri bidakomeye. Birakwirakwizwa cyane mu gihingwa, inyamaswa, nuhinga. Ikora imirimo itandukanye mubinyabuzima bitandukanye. Kubwibyo, acide ya oxalic ikunze gufatwa nkumurwanya kugirango ishishikarire kandi igakoresha amabuye y'agaciro. Anhydride yayo ni karuboni.

Ibiranga:Urupapuro rwa Monoclinic rutagira amabara cyangwa ifu yera cyangwa ifu yera, acide ya oxalic odorless by okiside, uburyohe bwa oxalic buryohe na synthesis. Kugabana kuri 150 ~ 160 ℃. Irashobora kubabara mu kirere gishyushye. 1G irashonga mumazi ya 7ml, 2ml Amazi abira, 2.5ml Ethanol, 1.8ML uteke, 5ml ether, 5ml glycerin, na belcernin, chloroform na peteroli na peteroli. 0.1Mol / l igisubizo gifite ph ya 1.3. Ubucucike ugereranije (amazi = 1) ni 1.653. Gushonga Ingingo ya 189.5 ℃.

Imiti yimiti:Acide ya Oxalic, azwi kandi nka aside ya glycolic, iboneka cyane mubiryo byateye. Acide ya oxalic ninkingi itagira ibara Crystal, shoke mumazi aho kuba mubintu bya kama nka ether,

Oxalate ifite ingaruka zikomeye kandi ni ubundi bwoko bwimiti yicyuma mubiryo byateye. Iyo aside ya oxalike ihujwe nibintu bimwe byisi bya alkaline, kwikeba kwayo biragabanuka cyane, nka calcium oxalate ni hafi gukosorwa mumazi. Kubwibyo, kuboneka kwa oxalic acide bigira ingaruka zikomeye kuri bioabwaiailebling yibinyabuzima byingenzi; Iyo aside ya oxalic ihujwe nibintu byinzibacyuho, bikozwe mubibazo byo gukosora biterwa nigikorwa cyo guhuza acide oxalic, kandi kuke kwiyongereye cyane.

Acide ya oxalic yatangiye kugabana kuri 100 ℃, yibajwe vuba kuri 125 ℃, kandi yibazwa cyane kuri 157 ℃, atangira kubora.

Irashobora kubyitwaramo na Alkali, irashobora gutanga imbaraga, Acyl Halolonye, ​​urimude reaction. Kugabanuka kandi birashobora kubaho, kandi ingaruka za demorbortilation zishobora kubaho munsi yubushyuhe. Anhydrous acide ni hygroscopique. Oxalic aside ihinduranya amazi-gushonga hamwe ninama nyinshi.

Oxalate isanzwe:1, sodium oxalate; 2, potasiyumu oxalate; 3, calcium oxalate; 4, oxalas; 5, Antimony Oxalate; 6, amonimium hydrogen oxalate; 7, magnesium oxalate 8, lithium oxalate.

Gusaba:

1. Umukozi utoroshye, umukozi uzwi, umukozi wacitse, kugabanya umukozi. Ikoreshwa mu kugena Beryllium, Calcium, Chromium, zahabu, Manganeri, Strontium, Thorium nandi yicyuma. Isesengura rya PicCrystal kuri sodium nibindi bintu. Gucisha Calcium, Magnesuium, Thoruum n'ibigize isi idasanzwe. Igisubizo gisanzwe kuri kalibration ya potasiyumu permandukate na cyuma gikemuka. Bleach. Irangi. Irashobora kandi gukoreshwa kugirango ikureho ingese kumyenda mu nganda zo kubaka mbere yo koza urukuta rwo hanze, kuko urukuta rwa alkaline rugomba gukomera.

2. Inganda za farumasi zikoreshwa mugukora aureomycin, oxystracycline, streeptomycline, hurptomycin, Borneol, Vitamine B12, penobarbital nibindi biyobyabwenge. Gucapa no gusiga Inganda zikoreshwa nkibitekerezo byamabara, Bleach, Umuganga Hagati. Inganda za plastics kugirango umusaruro wa PVC, Amino Plastiki, Urea - formaldehde plastike.

3. Yakoreshejwe nkumusemburo wa synthesis phhelicasi, retalytic reaction yoroheje, inzira irahagaze neza, kandi igihe kirageze. Acetone Oxalate igisubizo irashobora Catalyze gukiza reaction ya epoxy resin no kugabanya igihe. Ikoreshwa kandi nka synthetic urea formaldehyde resin, melamine formaldehyde resin ph regilator. Irashobora kandi kongerwaho muri polyvinyl formaldehyde amazi-afatika kugirango atezimbere umuvuduko wumye nimbaraga. Ikoreshwa kandi nka urea formaldehyde resin gukiza agent, ion ion ihenduza umukozi. Irashobora gukoreshwa nkihuse yo gutegura ibishishwa bifatika hamwe na kmno4 okiside kugirango wihutishe igipimo cya okiside no kugabanya igihe cyimyitwarire.

Nkumukozi ushimishije:

Acide ya Oxalic ikoreshwa cyane nko kugabanya igent na Bleach, ikoreshwa mugukora antibiyotike na Borneol nibindi biyobyabwenge, irangi rigabanya imipaka, irangi rigabanya umukozi, nibindi

Acide ya oxalic irashobora kandi gukoreshwa mu musaruro wa collat-molybdenum-aluminiyumu catalests, isuku y'ibyuma na marble, no kumenagura imyenda.

Ikoreshwa mu kugira isuku hejuru no kuvuza ibyuma, Gukuramo ibintu bidasanzwe by'isi, gucapa byisi no gusiga irangi, gutunganya uruhu, gutobora uruhu, nibindi.

Nkumukozi ugabanya:

Mu nganda zamanzo kama zikoreshwa cyane mu gukora hydroquinone, Pentarythriyone, Pentarythriosol, Pentarythriopol, Cobarythritol, Cobalthritol, COBALTthritol, Nickel Oxalate, Nickel Oxalate, Acide ya Gallic nibindi bikoresho byamavumba.

Inganda za plastics kugirango umusaruro wa PVC, Amino Plastike, Urea - formaldehde plastike, irangi, nibindi.

Inganda zirangi zikoreshwa mugukora base icyatsi nibindi.

Gucapa no gusiga irangi birashobora gusimbuza aside acetike, ikoreshwa nka pigment irangi ryamabara, umukozi uhazana.

Inganda za farumasi kugirango ukore aureomycin, tetracycline, streptomycin, gediri.

Byongeye kandi, aside oxalic irashobora kandi gukoreshwa muri synthesis ya oxatelate zitandukanye, oxalate na oxalayl oxalate, sodium oxalate, calcium oxalate nibindi bitanga umusaruro.

Uburyo bwo kubika:

1. Shyira ahantu hahana kandi ubukonje. Ubushuhe buhebuje-gihamya, amazi-yerekana amazi n'izuba. Ubushyuhe bwububiko ntibugomba kurenga 40 ℃.

2. Irinde oxide nibintu bya alkaline. Koresha imifuka ya polypropylene iboheshejwe n'amashashi ya pulasitike, 25kg / umufuka.

Muri rusange, acide ya oxalic ni imiti itandukanye hamwe na porogaramu nyinshi muburyo butandukanye. Imitungo yayo igahitamo neza yo gukora isuku, gutunganya no guhindaho, kandi ifite ibyifuzo byinshi mubyiciro, ubusitani no munganda. Nyamara, ingamba z'umutekano zigomba gufatwa mugihe ukoresheje iyi miti, nkuko bifite uburozi kandi irashobora kwangiza niba idaciwe neza.
