Oxalic acid

Oxalic acidchinhu chechinhu. Fomu yemakemikari ndeye h₂c₂o₄. Icho chigadzirwa che metabolic chezvisikwa. Iyo mbiri-chikamu chisina kusimba acid. Inogoverwa zvakanyanya muzvimedu, mhuka, uye fungul miviri. Iyo inoita mabasa akasiyana siyana mune akasiyana zvipenyu zvisikwa. Naizvozvo, qualic acid inowanzoonekwa seinopesana neyakaora uye yekushandiswa kwezvinhu zvemichero. Its Anhydride ndeye kabhoni trioxide.

Hunhu:Ruvara rwakaipa rwonzi Sublimation pa150 ~ 160 ℃. Inogona kunge yakakundwa mumhepo inopisa yakaoma. 1G ine mvura inonakidza mumvura 7ml, 2mml ethanol, 2.8ml ethanol, 1,8ml inobika ethanol, 100ml ether, 5.5ml glycerin, uye insoluble muBenzene, chloroform uye petroleum ether. 0.1mol / l mhinduro ine pH ye1.3. Dentives yerudzi (mvura = 1) is 1.653. Kunyungudika Pfungwa 189.5 ℃.

Makemikari Zvivakwa:Oxalic acid, anozivikanwawo se glycolic acid, inowanikwa zvakanyanya mune zvekudya zvekudya. Oxalic acid is a columnar crystal, nyarara mumvura kwete mu organic soles yakadai seErth,

Oxalate ine yakasimba yekubatanidza maitiro uye imwe mhando yesimbi yekuchera mumiririri mune chirimwa chikafu. Kana oxal acid inosanganiswa neimwe alkaline yepasi zvinhu, iyo solubility yakaderedzwa kwazvo, yakadai se calcium oxalate ingangoerekana yaita mvura. Naizvozvo, kuvapo kwe oxalic acid ine mhedzisiro yakanaka pakubata kwenyama yakakosha; Kana oxalic acid yakasanganiswa nezvimwe zvinhu zvekushanduka simbi, zvinyoro-nyoro zvinoumbwa zvinoumbwa nekuda kwekubatanidza chiito che oxal acid, uye yavo solubility yakawedzera.

Oxalic Acid yakatanga kuita se100 ℃, nekukurumidza zvakavanzika pa125

Unogona kuita naAlkali, unogona kuburitsa estation Kuderedza maitiro kunogona kuitikawo, uye kuyananisa zvinogadziriswa zvinogona kuitika pasi pekupisa. Anhydrous oxalic acid ndeye hygroscopic. Oxalic acid inoumba madhiri emvura ane simba nemarara mazhinji.

Oxalate:1, sollium olate; 2, potassium oxacolate; 3, calcium oxaclate; 4, ferus oxate; 5, Antimony Oxacolate; 6, amonium hydrogen oxitalate; 7, Magnesium Oxalate 8, Lithi Boalate.

Chikumbiro:

1. Kuoma mumiririri, masking mumiriri, akasarudzika mumiririri, kuderedza mumiririri. Izvo zvinoshandiswa pakutsunga kweBeryllium, Calcium, Chromium, Goridhe, Manganese, Strontium, Trorium uye mamwe masimbi ioni. Picodocrystal kuongororwa kweSodium uye zvimwe zvinhu. Fungidzira Calcium, magnesium, trorium uye zvisingawanzo zvepasi zvinhu. Solution Solution yeCalibration yePotassium Permonganate uye Suus Sulfate Mhinduro. Bleach. Dye rubatsiro. Inogona zvakare kushandiswa kubvisa ngura pane zvipfeko zviri muindasitiri yekuvaka usati wabhururuka madziro ekunze, nekuti madziro alkaline yakasimba inofanira kutanga yebras.

2. Pharmaceucal indasitiri yakashandiswa muAureomycin, Oxytetracycline, Streptomycin, Borneol, Vitamin B12, phenobarbital uye zvimwe zvinodhaka. Kudhinda uye indasitiri yekudyira inoshandiswa seyakaitwa neruvara, bleach, kurapwa kwepamoyo. Indasitiri yePurasitiki yekugadzirwa kwePVC, Amino Purastics, Urea - ForMALDEHDE CLASTICS.

3 Acetone Oxalate Solution inogona kuunganidza kurapa maitiro e epoxy resin uye kupfupisa kuporesa nguva. Zvakare inoshandiswa seSynthetic Urea forrea formaldehyde resin, Melamine FormEhdehyde Resin Ph Regulator. Inogona zvakare kuwedzerwa muPolyvinyl formanadehdehyde yemvura-inonamira inonamatira kuti uvandudze kumhanya uye kusanganisa simba. Zvakare inoshandiswawo seUrea formaldehyde resin kuronga mumiririri, metheni ion chelating mumiririri. Inogona kushandiswa seyinosimudzira yekugadzirira starch anominesives ine Kmno4 oxidant yekukurudzira iyo oxidation chiyero uye kupfupisa nguva yekuita.

Semumiriri wakasarudzika:

Oxalic Acid inonyanya kushandiswa sekudzora mumiririri uye bleach, inoshandiswa mukugadzirwa kwemishonga inorwisa mabhakitiriya uye zvimwe zvinodhaka zvisingawanzo simbisa

Oxalic Acid inogona zvakare kushandiswa mukugadzirwa kweCobalt-Molybdenum-Aluminum Catalysts, kuchenesa kwesimbi nemarble, uye kusviba kwemanyorerwo.

Inoshandiswa kune simbi yekuchenesa uye kurapwa, rare pasi pelement kubviswa, kudhinda machira uye dhayi, kugadzirira kweganda, kugadzirira kweganda, etcalyst.

Sekudzora mumiririri:

Mune iyo organic synthesis indasitiri inonyanya kushandiswa mukugadzirwa kwehydroquinone, pentaerythritol, cobalt oxacolate, nicker oxate, gallic acid uye zvimwe zvigadzirwa zvemakemikari.

Indasitiri yepurasitiki yekugadzirwa kwePVC, amino purasti, Urea - formaldehyde mapurasitiki, paint, nezvimwe.

Dhayi indasitiri inoshandiswa kugadzira base green uye zvichingodaro.

Kudhinda uye Dyeing Indasitiri inogona kutsiva acetic acid, inoshandiswa sekutyaira dhayi rubatsiro, kusanganisa mumiririri.

Indasitiri yechechi yekugadzira yeAureomycin, Tetracycline, Streptomycin, Ephedrine.

Mukuwedzera, oxal acid inogona zvakare kushandiswa mune synthesis yemhando dzakasiyana siyana, uye dieothyl zvigadzirwa, sodium oxalate, calcium oxacolate uye zvimwe zvigadzirwa zvinonyanya kubereka.

Nzira yekuchengetedza:

1. Chisimbiso munzvimbo yakaoma uye inotonhorera. Yakanyorova nyoro-chiratidzo, mvura-chiratidzo uye zuva-chiratidzo. Tembiricha yekuchengetedza haifanire kupfuura makumi mana ℃.

2. Ibva kure kubva kune oxides uye alkaline zvinhu. Shandisa Polypropyle yakarohwa mabhegi akaiswa nemapepa epurasitiki, 25kg / bhegi.

Zvakazara, oxalic acid is a shanduro yemakemikari yakawanda ine akawanda mashandiro mune akasiyana maindasitiri. Zvivakwa zvayo zvinoita kuti ive sarudzo yakanakira kuchenesa, kunatswa uye kusviba, uye ine zviyero zvakati wandei muzvinyorwa zvemitezo, maindasitiri ehondo uye meseturu. Nekudaro, kuchengetedzwa kwekuchengetedza kunofanirwa kutorwa kana uchishandisa kemikari ino, sezvo ichine chepfu uye inogona kukuvadza kana isina kubatwa nemazvo.
