Oxalic asidhi chinhu cheorganic chine chimiro chemakemikari H₂C₂O₄.Imetabolite yezvipenyu.Icho chinonzi dibasic weak acid.Inoparadzirwa zvakanyanya mumiti, mhuka uye fungi, uye inotamba mabasa akasiyana muzvisikwa zvakasiyana.Asidhi yayo anhydride ndiyo kabhoni trioxide.Kutaridzika kweoxalic acid haina ruvara monoclinic flake kana prismatic crystal kana chena poda, isina kunhuhwirira, inovava kuravira, inonyungudika nyore mumvura asi isinganyungudika muorganic solvents senge ether.Huremu hwema molecular oxalic acid ndeye 90.0349.
Kushandiswa kweoxalic acid: inogadzirisa agent, masking agent, precipitating agent, inoderedza agent.
1, semumiririri we bleaching
Oxalic acid inonyanya kushandiswa sechinhu chinoderedza uye bleaching agent, inoshandiswa mukugadzirwa kwemishonga yakadai semishonga inorwisa mabhakitiriya neborneol, sechinhu chinonyungudutsa chekubvisa simbi dzisingawanzoitiki, sechinhu chinoderedza dhayi, uye sechinhu chinopisa.
Oxalic acid inoshandiswawo mukugadzirwa kwecobalt-molybdenum-aluminium catalysts, kucheneswa kwesimbi nemarble, uye kucheneswa kwemachira.
2. Sechinhu chinoderedza
Muindasitiri ye organic synthesis, inonyanya kushandiswa kugadzira zvigadzirwa zvemakemikari zvakaita sehydroquinone, pentaerythritol, cobalt oxalate, nickel oxalate, uye gallic acid.
Indasitiri yepurasitiki inoshandiswa mukugadzira polyvinyl chloride, aminoplastics, urea-formaldehyde mapurasitiki, lacquer mapepa, nezvimwe.
Indasitiri yedhayi inoshandiswa mukugadzira munyu-based magenta green, nezvimwe.
Muindasitiri yekudhinda nekudhaya, inogona kutsiva acetic acid uye kushandiswa semuvara wekuvandudza rubatsiro uye bleaching agent ye pigment dhayi.
Indasitiri yemishonga inoshandiswa mukugadzira chlortetracycline, oxytetracycline, tetracycline, streptomycin, uye ephedrine.
Pamusoro pezvo, oxalic acid inogona zvakare kushandiswa kugadzira zvigadzirwa zvakasiyana senge oxalate, oxalate uye oxalamide, pakati peiyo diethyl oxalate, sodium oxalate uye calcium oxalate ndiyo inonyanya kugadzira.
3. Somufi
Antimony oxalate inogona kushandiswa se mordant, uye ferric ammonium oxalate inhengo yekudhinda mapurani.
4 Rust kubvisa basa
Oxalic acid inogona kushandiswa kubvisa ngura: tenga bhodhoro re oxalic acid kubva muchitoro chinotengesa makemikari reagents, tora mamwe, gadzira mhinduro nemvura inodziya, uise kune tsvina uye uipukuta.(Cherechedza: Chenjera paunenge uchishandisa, oxalic acid inoparadza zvakanyanya kusimbi isina tsvina. Oxalic acid ine high concentration zvakare iri nyore kuodza maoko. Uye iyo acid oxalate inogadzirwa inonyungudika, asi ine mwero wehuturu. Usaidye. pakushandisa . Mushure mekunge ganda rasangana neoxalic acid, rinofanira kugezwa nemvura nenguva.)
Oxalic acid kuchengetedza
1. Chengetedza munzvimbo yakaoma uye inotonhorera.Yakanyatso hunyoro-huchapupu, kusapinda kwemvura, sunscreen.Tembiricha yekuchengeta haifanirwe kudarika 40 ℃.
2. Ramba kure nemaokisi uye alkaline zvinhu.Yakaiswa muhomwe yepolypropylene yakarukwa yakaiswa neplastic bag.
