ʻO ka ʻakika Oxalic kahi mea olaola me ke ʻano kemika H₂C₂O₄.He metabolite ia o nā mea ola.He ʻakika nāwaliwali dibasic.Hoʻolaha nui ʻia i nā mea kanu, nā holoholona a me nā haʻi, a pāʻani i nā hana like ʻole i nā mea ola like ʻole.ʻO kona waikawa anhydride he carbon trioxide.ʻO ka hiʻohiʻona o ka waika oxalic he monoclinic flake kala ʻole a i ʻole ke aniani prismatic a i ʻole ka pauka keʻokeʻo, ʻono ʻole, ʻono ʻawaʻawa, hiki ke hoʻoheheʻe ʻia i loko o ka wai akā ʻaʻole hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe kūlohelohe e like me ka ether.ʻO 90.0349 ke kaumaha molekala o ka ʻakika oxalic.
Nā hoʻohana o ka oxalic acid: complexing agent, masking agent, precipitating agent, reducing agent.
1, ma ke ʻano he mea hoʻomaʻemaʻe
Hoʻohana nui ʻia ka waikawa Oxalic ma ke ʻano he mea hoʻohaʻahaʻa a me ka bleaching agent, i hoʻohana ʻia i ka hana ʻana i nā lāʻau lapaʻau e like me nā antibiotics a me borneol, ma ke ʻano he mea hoʻoheheʻe no ka unuhi ʻana i nā metala laʻa, ma ke ʻano he mea hoʻoheheʻe dye, a ma ke ʻano he tanning agent.
Hoʻohana pū ʻia ka waikawa Oxalic i ka hana ʻana i nā catalysts cobalt-molybdenum-aluminum, ka hoʻomaʻemaʻe ʻana i nā metala a me ke kinikini, a me ka bleaching o nā textiles.
2. Ma ke ano he mea hoemi
I ka ʻoihana synthesis organik, hoʻohana nui ia e hana i nā huahana kemika e like me ka hydroquinone, pentaerythritol, cobalt oxalate, nickel oxalate, a me ka waikawa gallic.
Hoʻohana ʻia ka ʻoihana plastics i ka hana ʻana i ka polyvinyl chloride, aminoplastics, urea-formaldehyde plastics, lacquer sheets, etc.
Hoʻohana ʻia ka ʻoihana dye i ka hana ʻana i ka ʻōmaʻomaʻo magenta paʻakai, etc.
Ma ka ʻoihana paʻi a me ka hoʻoluʻu ʻana, hiki ke hoʻololi i ka acetic acid a hoʻohana ʻia ma ke ʻano he kōkua hoʻomohala kala a me ka bleaching agent no nā kala puaʻa.
Hoʻohana ʻia ka ʻoihana lāʻau lapaʻau i ka hana ʻana o chlortetracycline, oxytetracycline, tetracycline, streptomycin, a me ephedrine.
Eia kekahi, hiki ke hoʻohana ʻia ka oxalic acid e synthesize i nā huahana like ʻole e like me ka oxalate, oxalate a me ka oxalamide, ma waena o ka diethyl oxalate, sodium oxalate a me ka calcium oxalate ka mea nui loa.
3. Me he mordant la
Hiki ke hoʻohana ʻia ka Antimony oxalate ma ke ʻano he mordant, a ʻo ka ferric ammonium oxalate kahi mea hana no ka paʻi ʻana i nā kiʻi.
4 Hana wehe ʻana i ka ʻōpala
Hiki ke hoʻohana ʻia ka ʻakika oxalic no ka wehe ʻana i ka ʻōpala: kūʻai aku i ʻōmole oxalic acid mai kahi hale kūʻai e kūʻai aku ana i nā mea hoʻohui kemika, e lawe i kekahi, e hana i ka hopena me ka wai mahana, e hoʻopili i ka ʻeleʻele a holoi.(E hoʻomanaʻo: E makaʻala i ka hoʻohana ʻana, he mea ʻino loa ka ʻakika oxalic i ke kila kila. ʻO ka waikawa oxalic me ka ʻike kiʻekiʻe he maʻalahi hoʻi e ʻino i nā lima. ke hoʻohana 。 Ma hope o ka pili ʻana o ka ʻili me ka waika oxalic, pono e holoi ʻia me ka wai i ka manawa.)
ʻO ka mālama ʻana i ka waikawa oxalic
1. E mālama i kahi maloʻo a maʻalili.Hoʻopaʻa paʻa ʻole i ka wai, ka pale lā.ʻAʻole pono ka mahana mālama ma mua o 40 ℃.
2. E hoʻokaʻawale i nā oxides a me nā mea alkaline.Hoʻopili ʻia i loko o ka ʻeke ulana polypropylene i hoʻopaʻa ʻia me ka ʻeke plastik.
