Mugadziri Akanaka Mutengo Oxalic Acid CAS: 144-62-7

tsananguro pfupi:

Oxalic asidhi yakasimba dicarboxylic asidhi inowanikwa muzvirimwa zvakawanda nemiriwo, kazhinji secalcium kana potassium munyu. Oxalic acid ndiyo chete inogoneka musanganiswa umo mapoka maviri ecarboxyl anobatanidzwa zvakananga; nokuda kwechikonzero ichi oxalic asidhi ndeimwe yakasimba organic acids. Kusiyana nemamwe carboxylic acids (kunze kweformic acid), iri nyore oxidized; izvi zvinoita kuti zvive zvakakosha sechinhu chinoderedza kutora mifananidzo, kuchena, uye kubvisa inki. Oxalic acid inowanzo gadzirwa nekupisa sodium fomati ine sodium hydroxide kuti iite sodium oxalate, iyo inoshandurwa kuita calcium oxalate uye inobatwa ne sulfuric acid kuti iwane oxalic acid yemahara.
huwandu hweoxalic acid hwakanyanya kuderera muzvirimwa zvakawanda uye zvidyarwa-zvikafu, asi pane zvakakwana muspinachi, chard uye beet girini kuvhiringidza kutorwa kwecalcium zvinomera izvi zvakare.
Inogadzirwa mumuviri nemetabolism ye glyoxylic acid kana ascorbic acid. Haina metabolized asi inobuditswa muweti. Inoshandiswa seanalytical reagent uye general reducing agent.Oxalic acid is a natural acaricide inoshandiswa kurapa mite yevarroa mumakoloni asina / low brood, mapakeji, kana kuputika. Vaporized oxalic acid inoshandiswa nevamwe varimi nyuchi semushonga wezvipembenene kurwisa utachiona hweVarroa mite.

Chemical Properties:Oxalic acid ihupfu husina ruvara, husina hwema, kana kuti granular solid. Iyo anhydrous form (COOH)2 haina kunhuwa, yakachena yakasimba; mushonga wacho imvura isina ruvara.

Kushandiswa kweOxalic Acid

1. Oxalic acid inogona kunyanya kushandiswa seanoderedza ajenti uye bleaching agent, mordant yekudhaya uye kudhinda indasitiri, inoshandiswawo mukunatsa isingawanzo simbi, kuumbwa kweakasiyana oxalate ester amide, oxalate uye uswa, nezvimwe.

2. Inoshandiswa seanalytical reagent.

3. Inoshandiswa sema laboratory reagents, chromatography yekuongorora reagent, dhayi yepakati uye yakajairwa zvinhu.

4. Oxalic acid inonyanya kushandiswa kugadzira mishonga yakadai semishonga inorwisa mabhakitiriya uye borneol uye solvent yekubudisa simbi isingawanzoitiki, kuderedza agent uye dhayi, tanning agent, etc. Mukuwedzera, oxalic acid inogonawo kushandiswa pakugadzirwa kwemhando dzakasiyana-siyana dze oxalate ester, oxalate, uye oxamide ine diethyl oxalate, sodium oxalate ine oxalate yakakura uye calcium oxalate. Oxalate inogona zvakare kushandiswa kugadzira cobalt-molybdenum-alumina catalyst, kuchenesa simbi nemarble pamwe nekucheneswa kwemachira.

Zvishandiso Zvekurima:Oxalic acid, (COOH)2, inonziwo ethanedioic acid, ichena, ine crystalline yakasimba, inonyungudika zvishoma mumvura. Iyo inongoitika yakasikwa yakanyanya oxidized organic compound ine yakakosha chelating chiitiko. Iine acidic yakasimba uye ine chepfu, inogadzirwa nemiti yakawanda se sorrel (sourwood), mashizha emashizha e rhubarb, bark eucalyptus uye midzi yakawanda yemiti. Mumaseru ezvirimwa nematishu, oxalic acid inounganidzwa senge sodium, potassium kana calcium oxalate, iyo yekupedzisira inoitika sekristaro. Zvakare, munyu weoxalic acids unopinda mumitumbi yemhuka nevanhu, zvichikonzera kusagadzikana kwepathological, zvichienderana nehuwandu hunopedzwa. Mhando dzakawanda dzefungi seAspergillus, Penicillium, Mucor, pamwe nemamwe lichens uye slime molds zvinogadzira calcium oxalate makristasi. Pakufa kweaya ma microorganisms, zvirimwa nemhuka, munyu unoburitswa muvhu, zvichikonzera huwandu hwehuturu. Nekudaro, maoxalate-anosvibisa tupukanana, anonzi Oxalobacter formigenes, anoderedza kunyudzwa kweoxalate mumhuka nevanhu.

Oxalic acid ndiyo yekutanga yenhevedzano yedicarboxylic acids. Inoshandiswa (a) sechinhu chinopisa chemavara senge ngura kana inki, (b) mukugadzirwa kwematehwe nematehwe, uye (c) semonoglyceryl oxalate mukugadzirwa kwealli1 doro uye formic acid.
