Oxalic acid

Kufotokozera kwaifupi:

Ndi mtundu wa organic acid, ndi mankhwala a metabolic a acids, a asidi, amagawidwa kwambiri muzomera, nyama ndi bowa, ndipo m'matumbo osiyanasiyana amagwira ntchito zosiyanasiyana. Zapezeka kuti oxalic acid ndi olemera pamitundu yoposa 100 ya mbewu zopitilira 100, amaran sipipi, beent, arro, mbatata yokoma ndi rhubarb. Chifukwa oxalic acid amatha kuchepetsa bioaavailability ya zinthu zam'minera, zimawerengedwa ngati wotsutsana ndi mayamwidwe ndi kugwiritsa ntchito zinthu zam'm mineral. Anhydride yake ndi carbon sesquoxide.

Oxalic acid ndi ofooka acid. Woyambitsa May-Order Loven Ka1 = 5.9 × 10-2 ndi yachiwiri - inoit-dongosolo lokhalapo KA2 = 6.4 × 10-5. Ili ndi wambani. Itha kusokoneza maziko, discolor chizindikiritso, ndikumasula mpweya woipa malinga ndi mgwirizano wa carbemin. Imakhala ndi kuthekera kwamphamvu ndipo ndikosavuta kukhala oxidizere mu kaboni dayokisi ndi madzi mwa wogula. Acid potaziyamu permanganate (kmno4) yankho limatha kusungunuka ndikuchepetsedwa mpaka 2-valencese ion.

Kupatsa Kuwonjezera

Posindikiza ndi kulowetsa makampani opanga, imatha kusintha acetic acid kuti apange mitundu yoyambira. Chogwiritsidwa ntchito ngati colorant komanso bulichi pa utoto wa utoto. Itha kuphatikizidwa ndi mankhwala ena kuti apange utoto, ndipo amathanso kugwiritsidwa ntchito ngati chibilire cha utoto, potero kufalitsa moyo wa utoto.

Yezikitsani

Kugwiritsa ntchito Zeolite monga momwe zimakhalira pamakampani ogulitsa mapepala kumatha kukonza magwiridwe antchito ndi pepala lake.

Makampani opanga mapulasitiki

Makampani ogulitsa za plastic kuti akupanga polyvinyl chloride, amino pulasitiki, urea formaldehyde plastics, tchipisi cha utoto ndi zina zotero.

Makampani Opanga Photovovoltaltaltaltaltaltaltaltaltaltaltaltaltaltaltaltaltaltal

Oxalic acid amagwiritsidwanso ntchito pazinthu za Photovovultaltaltaltaltaltaltaltaltaltaltaltal. Oxachic acid imatha kugwiritsidwa ntchito popanga liricon chofunda cha mapanelo a dzuwa, akuthandizira kuchepetsa zofooka pamtunda wa silicon.

Kutsuka mchenga

Oxachic acid ophatikizidwa ndi hydrochloric acid ndi hydrofluoric acid amatha kuchitapo kanthu osamba mchenga.

Synthesis catalyst

Monga chothandizira cha phenolic synthesis, zovuta zomwe zimapangitsa ndizofatsa, njirayi imakhala yokhazikika, ndipo nthawi ndiyotalikirapo kwambiri. Acetone oxalate Solution amatha kuthana ndi zomwe Epoxy zimayendera ndikufupikitsa nthawi yodala. Amagwiritsidwanso ntchito ngati pulogalamu ya pH ya synthesis ya urea-formaldehyde utoto ndi melamine formaldehyde utoto. Itha kuwonjezeredwanso ku sulvinyl polyvinyl amalimbikitsa kukonza liwiro louma ndi kulimba mtima. Itha kugwiritsidwanso ntchito ngati kuthira wothandizira wa urea-formaldehyde utoto ndi chitsulo cha ion. Itha kugwiritsidwa ntchito ngati wokuthandizani kukonzekeretsa wowuma wa kmno4 oxidizing wothandizira kuti athetse kuchuluka kwa oxidation ndikufupikitsa nthawi.
