Oxalic acid

Tsananguro pfupi:

Iro rudzi rweganho rejecric, chigadzirwa che metabolic chezvisikwa, binary acid, chakagoverwa zvakanyanya mune zvirimwa, mhuka nefungus, uye pazvinhu zvehupenyu zvakasiyana zvinotamba zvakasiyana. Iyo yakawanikwa kuti xoalic acid yakapfuma mumhando dzinopfuura zana dzezvirimwa, kunyanya sipinach, amaranth, beet, taro, taro, taro, taro, taro mbatatisi uye rhubarb. Nekuti oxal acid inogona kuderedza iyo yekubvarura zvinhu zvemaminerari, inoonekwa seinopesana neyekupesana nekunyudza uye kushandiswa kwezvinhu zvemichero. Its Anhydride ndeye kabhoni sesquioxide.

(Scope yeChikumbiro Chekushandisa 'Chigadzirwa Kushandiswa')

Oxalic acid ndeye isina kusimba acid. Iyo yekutanga-kuraira ionization nguva dzose ka1 = 5.9 × 10-2 uye yechipiri-Order ionization nguva dzose K2 = 6.4 × 10-5. Iyo yakaringana kujairika. Izvo zvinogona kusimudzira chigadziko, discolor chiratidzo, uye kuburitsa carbon dioxide nekudyidzana necarbonates. Iyo ine kuderedzwa kwakasimba uye kuri nyore kuve oxidized mu carbon dioxide uye mvura ne oxidizing mumiririri. Acid potassium permonganate (KMNO4) mhinduro inogona kuderedzwa uye kuderedzwa kusvika ku2-valence manganese ion.

Kushandiswa kwechigadzirwa

Dyeing anonyanya kuwedzera

Mukudhinda uye indasitiri yekudhinda, inogona kutsiva acetic acid kuti iite mavara ekutanga. Inoshandiswa seye colant uye breach ye pigment dhayi. Inogona kusanganiswa nemamwe makemikari ekugadzira madhiri, uye anogona kushandiswawo sechigumbura kumadyadhi, nekudaro achiwedzera hupenyu hwemakadhi.

Shuwa

Kushandiswa kweEziri sezvo Filler muindasitiri yepepa kunogona kunatsiridza kuita uye kunaka kwepepa, zvekutora kwemvura zvinowedzerwa, zviri nyore kutema, kunyorera zvinovandudzwa, uye zvine kumwe kuramba moto.

Indasitiri yePurasitiki

Indasitiri yePurasitiki yekugadzirwa kwePolyvinyl chloride, amino purasti, Urea formaldehdehde purastics, pendi machipisi uye zvichingodaro.

Fotovoltaic indasitiri

Oxoal acid inoshandiswawo muindasitiri yemoto. Oxalic Acid inogona kushandiswa kuita silicon Wafers yemapani eSolar, achibatsira kuderedza kuremara pamusoro peiyo silicon wafers.

Kushambidza kwejecha

Oxalic acid yakasanganiswa neHydrochloric acid uye hydrofluorgic acid inogona kuita pane acid yekushambidza jecha quartz.

Synthesis catalyst

Sechiro chetinoita phenolol resin synthesis, iyo Catalytic maitiro ndeye nyoro, maitiro akagadzikana, uye nguva yakareba kwazvo. Acetone Oxalate Solution inogona kuunganidza kuporesa kuita kwe epoxy resin uye kupfupisa kurapa nguva yekurapa. Iyo inoshandiswawo sePH mutungamiriri weSynthesis yeUrea-formaldehyde resin uye Meleline formineehdehyde resin. Inogona zvakare kuwedzerwa kune mvura-inokandwa polyvinyl doro chinonamatira kuti uvandudze kumhanya kwekuomesa uye kusanganisa simba. Inogona zvakare kushandiswa sekuporesa mumiririri weUrea-formaldehyde resin uye metheni ion chelating mumiririri. Inogona kushandiswa seye accelerator kugadzirira starch binder ne kno4 oxidizing mumiririri wekumhanyisa oxidation rate uye kupfupisa nguva yekuita.
