Oxalic Acid

Kufotokozera mwachidule:

Ndi mtundu wa asidi organic, ndi kagayidwe kachakudya cha zamoyo, bayinare asidi, ambiri kufalitsidwa mu zomera, nyama ndi bowa, ndipo mu zamoyo zosiyanasiyana zimagwira ntchito zosiyanasiyana.Zapezeka kuti asidi oxalic ali wolemera mu mitundu yoposa 100 ya zomera, makamaka sipinachi, amaranth, beet, purslane, taro, mbatata ndi rhubarb.Chifukwa oxalic acid imatha kuchepetsa bioavailability wa zinthu zamchere, imatengedwa ngati mdani pakuyamwa ndi kugwiritsa ntchito zinthu zamchere.Anhydride yake ndi carbon sesquioxide.

Kugwiritsa Ntchito Mankhwala

Chowonjezera cha utoto

M'makampani osindikizira ndi opaka utoto, amatha kulowa m'malo mwa asidi kuti apange mitundu yoyambirira.Amagwiritsidwa ntchito ngati colorant ndi bleach kwa utoto wa pigment.Ikhoza kuphatikizidwa ndi mankhwala ena kuti apange utoto, ndipo ingagwiritsidwenso ntchito ngati chokhazikika cha utoto, potero kuwonjezera moyo wa utoto.

Woyeretsa

Kugwiritsa ntchito zeolite ngati zodzaza mumakampani opanga mapepala kumatha kupititsa patsogolo magwiridwe antchito ndi mawonekedwe a pepala, kotero kuti porosity yake ichuluke, kuyamwa kwamadzi kumakulitsidwa, kumakhala kosavuta kudula, kulembera kumatheka, ndipo kumakhala ndi kukana moto.

Makampani apulasitiki

Makampani apulasitiki opangira polyvinyl chloride, mapulasitiki amino, mapulasitiki a urea formaldehyde, tchipisi ta utoto ndi zina zotero.

Makampani a Photovoltaic

Oxalic acid imagwiritsidwanso ntchito pamakampani a photovoltaic.Oxalic acid angagwiritsidwe ntchito kupanga zowotcha za silicon pamapanelo adzuwa, kuthandiza kuchepetsa zolakwika pamwamba pa zowotcha za silicon.

Kutsuka mchenga

Oxalic acid pamodzi ndi hydrochloric acid ndi hydrofluoric acid akhoza kuchitapo kanthu pa kutsuka kwa asidi kwa mchenga wa quartz.

Synthesis chothandizira

Monga chothandizira kaphatikizidwe ka phenolic resin, chothandizira chimakhala chochepa, ndondomekoyi imakhala yokhazikika, ndipo nthawi ndi yayitali kwambiri.Njira yothetsera acetone oxalate imatha kuyambitsa machiritso a epoxy resin ndikufupikitsa nthawi yochiritsa.Amagwiritsidwanso ntchito ngati pH regulator pakuphatikizika kwa urea-formaldehyde resin ndi melamine formaldehyde resin.Itha kuwonjezeredwa ku zomatira zosungunuka zamadzi za polyvinyl kuti muwongolere liwiro lowuma komanso mphamvu yomangirira.Itha kugwiritsidwanso ntchito ngati wochiritsa wa urea-formaldehyde utomoni ndi chitsulo ion chelating wothandizira.Itha kugwiritsidwa ntchito ngati accelerator kukonzekera wowuma binder ndi KMnO4 oxidizing agent kuti ifulumizitse kugunda kwa okosijeni ndikufupikitsa nthawi yochitira.
