AIKI OXALIC

ʻOxalic acidhe mea olaola.ʻO ke ʻano kemika ʻo H₂C₂O₄.He huahana metabolic o nā mea ola.He ʻakika nāwaliwali ʻelua ʻāpana.Hoʻolaha nui ʻia i nā kino mea kanu, holoholona, ​​a me nā kino fungal.Hana ia i nā hana like ʻole i nā mea ola like ʻole.No laila, ʻike pinepine ʻia ka waikawa oxalic ma ke ʻano he antagonist no ka absorption a me ka hoʻohana ʻana i nā mea mineral.ʻO kāna anhydride ka carbon trioxide.

Nā hiʻohiʻona:ʻO ka pepa monoclinic kala ʻole a i ʻole ke aniani prismatic a i ʻole ka pauka keʻokeʻo, ka ʻakika oxalic ʻaʻala ʻole ma o ka hoʻoheheʻe ʻana, ka ʻono o ka oxalic acid ma ka synthesis.Sublimation ma 150 ~ 160 ℃.Hiki ke pale ʻia i ka ea maloʻo wela.Hiki ke hoʻoheheʻe ʻia ka 1g i ka wai 7mL, 2mL wai paila, 2.5mL ethanol, 1.8mL paila ethanol, 100mL etera, 5.5mL glycerin, a hiki ʻole ke hoʻoheheʻe ʻia i loko o benzene, chloroform a me ka ʻaila etera.He 1.3 ka pH o 0.1mol/L.ʻO ka mānoanoa pili (wai =1) he 1.653.Ka helu hehee 189.5 ℃.

Nā waiwai kemika:ʻO ka waikawa oxalic, i ʻike ʻia ʻo glycolic acid, loaʻa nui i nā meaʻai mea kanu.ʻO ka ʻakika Oxalic he aniani kolamu kala ʻole, hiki ke hoʻoheheʻe ʻia i ka wai ma mua o nā mea hoʻoheheʻe kūlohelohe e like me ka ether,

He hopena koʻikoʻi ko Oxalate a ʻo ia kekahi ʻano mea hoʻoheheʻe metala i ka meaʻai mea kanu.Ke hui pū ʻia ka ʻakika oxalic me kekahi mau mea metala honua alkaline, hoʻemi nui ʻia kona solubility, e like me ka calcium oxalate aneane hiki ʻole ke hoʻoheheʻe ʻia i ka wai.No laila, he hopena nui ka loaʻa ʻana o ka oxalic acid i ka bioavailability o nā mineral pono;Ke hui pū ʻia ka ʻakika oxalic me kekahi mau mea metala transitional, ua hoʻokumu ʻia nā paʻakikī hiki ke hoʻoheheʻe ʻia ma muli o ka hana coordination o ka waikawa oxalic, a ua hoʻonui nui ʻia ko lākou solubility.

Hoʻomaka ka ʻakika Oxalic e hoʻohaʻahaʻa i ka 100 ℃, hoʻoheheʻe koke ʻia ma 125 ℃, a hoʻohaʻahaʻa nui ʻia ma 157 ℃, a hoʻomaka e decompose.

Hiki ke hana me ka alkali, hiki ke hana i ka esterification, acyl halogenation, amide reaction.Hiki ke hana ʻia nā hopena hoʻēmi, a hiki ke hana ʻia nā hopena decarboxylation ma lalo o ka wela.He hygroscopic ka waikawa oxalic anhydrous.Hoʻokumu ka ʻakika Oxalic i nā paʻakikī hiki ke hoʻoheheʻe ʻia i ka wai me nā metala he nui.

Oxalate maʻamau:1, Sodium oxalate;2, Potassium oxalate;3, Calcium oxalate;4, Ferrous oxalate;5, Antimony oxalate;6, Ammonium hydrogen oxalate;7, Magnesium oxalate 8, Lithium oxalate.

Noi:

1. Mea hana paʻakikī, masking agent, precipitating agent, reducing agent.Hoʻohana ʻia ia no ka hoʻoholo ʻana i ka beryllium, calcium, chromium, gula, manganese, strontium, thorium a me nā ion metala ʻē aʻe.ʻIkepili Picocrystal no ka sodium a me nā mea ʻē aʻe.E hoʻoheheʻe i ka calcium, ka magnesium, ka thorium a me nā mea ʻeleʻele honua.ʻO ka hopena maʻamau no ka calibration o ka potassium permanganate a me ka cerous sulfate solutions.Bleak.Kōkua kala.Hiki ke hoʻohana ʻia no ka wehe ʻana i ka ʻōpala o nā lole i ka ʻoihana hale ma mua o ka palaki ʻana i ka uhi o ka paia o waho, no ka mea, ikaika ka alkaline o ka paia e pono ke kāhili mua i ka oxalic acid alkali.

2. ʻOihana lāʻau lapaʻau i hoʻohana ʻia i ka hana ʻana o aureomycin, oxytetracycline, streptomycin, borneol, vitamin B12, phenobarbital a me nā lāʻau ʻē aʻe.ʻO ka ʻoihana paʻi a me ka waihoʻoluʻu i hoʻohana ʻia ma ke ʻano he kōkua kala, bleach, waena lapaʻau.ʻO ka ʻoihana plastik no ka hana ʻana o PVC, amino plastics, urea - formaldehyde plastics.

3. Hoʻohana ʻia ma ke ʻano he catalyst no ka phenolic resin synthesis, ʻoluʻolu ka hopena catalytic, paʻa ke kaʻina hana, a ʻo ka lōʻihi ka lōʻihi.Hiki i ka hopena o ka Acetone oxalate ke hoʻopau i ka hoʻōla ʻana o ka epoxy resin a hoʻopōkole i ka manawa hoʻōla.Hoʻohana pū ʻia e like me ka resin urea formaldehyde synthetic, melamine formaldehyde resin pH regulator.Hiki ke hoʻohui ʻia i loko o ka polyvinyl formaldehyde wai-soluble adhesive e hoʻomaikaʻi i ka wikiwiki maloʻo a me ka ikaika paʻa.Hoʻohana pū ʻia e like me ka urea formaldehyde resin curing agent, metala ion chelating agent.Hiki ke hoʻohana ʻia e like me ka wikiwiki no ka hoʻomākaukau ʻana i nā adhesive starch me ka KMnO4 oxidant e hoʻolalelale i ka nui o ka oxidation a hoʻopōkole i ka manawa pane.

Ma ke ʻano he mea hoʻomaʻemaʻe:

Hoʻohana nui ʻia ka waikawa Oxalic e like me ka mea hoʻohaʻahaʻa a me ka bleach, i hoʻohana ʻia i ka hana ʻana i nā lāʻau antibiotic a me borneol a me nā lāʻau lapaʻau ʻē aʻe, a me ka hoʻomaʻemaʻe ʻana i nā metala paʻa ʻole, ka mea hoʻohaʻahaʻa dye, tanning agent, etc.

Hiki ke hoʻohana ʻia ka ʻakika Oxalic i ka hana ʻana i nā catalysts cobalt-molybdenum-aluminum, hoʻomaʻemaʻe i nā metala a me nā kinikini, a me ka bleaching o nā textiles.

Hoʻohana ʻia no ka hoʻomaʻemaʻe ʻana a me ka mālama ʻana i ka ʻili metala, ka ʻili ʻana o ka honua ʻeleʻele, ka paʻi textile a me ke kala, ka hana ʻili, ka hoʻomākaukau catalyst, etc.

Ma ke ʻano he mea hoʻohaʻahaʻa:

Hoʻohana nui ʻia ka ʻoihana synthesis organik i ka hana ʻana o ka hydroquinone, pentaerythritol, cobalt oxalate, nickel oxalate, gallic acid a me nā huahana kemika.

ʻO ka ʻoihana plastik no ka hana ʻana o PVC, amino plastics, urea - formaldehyde plastics, pena, etc.

Hoʻohana ʻia ka ʻoihana dye e hana i ka ʻōmaʻomaʻo kumu a pēlā aku.

Hiki ke hoʻololi i ka ʻoihana paʻi a me ka waihoʻoluʻu ʻana i ka acetic acid, hoʻohana ʻia e like me ke kōkua kala kala puaʻa, bleaching agent.

ʻO ka ʻoihana lāʻau lapaʻau no ka hana ʻana o aureomycin, tetracycline, streptomycin, ephedrine.

Eia kekahi, hiki ke hoʻohana ʻia ka waikawa oxalic i ka synthesis o nā ʻano oxalate ester, oxalate a me nā huahana oxalamide, a ʻo diethyl oxalate, sodium oxalate, calcium oxalate a me nā huahana ʻē aʻe ka mea nui loa.

Ke ala mālama:

1. E sila i kahi maloʻo a anuanu.Hoʻopaʻa paʻa i ka moisture, pale wai a me ka lā.ʻAʻole pono ka mahana mālama ma mua o 40 ℃.

2. E hoʻokaʻawale i nā oxides a me nā mea alkaline.E hoʻohana i nā ʻeke ulana polypropylene i hoʻopaʻa ʻia me nā ʻeke plastik, 25kg/ʻeke.

ʻO ka holoʻokoʻa, ʻo ka waika oxalic kahi kemika maʻamau me nā noi he nui i nā ʻano ʻoihana like ʻole.ʻO kāna mau waiwai he koho maikaʻi loa ia no ka hoʻomaʻemaʻe, hoʻomaʻemaʻe a me ka bleaching, a he nui nā noi i loko o ka ʻoihana textile, māla a me nā mea hana metala.Eia nō naʻe, pono e mālama i ka palekana i ka wā e hoʻohana ai i kēia kemika, no ka mea he mea ʻawaʻawa a hiki ke pōʻino inā ʻaʻole mālama pono ʻia.
