He aha ka ʻokoʻa ma waena o ka waikawa Oxalic a me ka waikawa Acetic?

He aha ka ʻokoʻa ma waena o ka waikawa Oxalic a me ʻAkika ʻAketika?
No ka hoʻokaʻawale ʻana i ka waikawa oxalic a me ka waikawa acetic, hiki iā mākou ke hoʻohālikelike iā lāua mai nā ʻano like ʻole e like me ke ʻano kemika, nā waiwai, a me nā noi hana. ʻOiai ʻo nā mea ʻelua no nā waikawa organik, ʻo nā ʻokoʻa i ko lākou mau ʻano a me nā ʻano e alakaʻi ai i nā ʻano like ʻole ma ke ʻano, nā hopena kemika, a me ka hoʻohana ʻana o ke kanaka.

ʻO ka mea mua, e nānā kākou i kā lākou mau hoʻohui kemika.
ʻO ka waikawa oxalic, i ʻike ʻia ma ke ʻano kemika ʻo ka waikawa ethanedioic, aia i loko o ia mau mea ʻelua mau hui carboxyl (-COOH) i loko o kona ʻano molekala, me ke ʻano molekala H₂C₂O₄. Ua like ia me kahi molekala e lawe ana i ʻelua mau hui waikawa, mākaukau e hoʻokuʻu i ʻelua mau iona hydrogen.

ʻO ka waikawa acetic, i ʻike ʻia hoʻi ʻo ka waikawa ethanoic, aia i loko o hoʻokahi wale nō hui carboxyl, me ke ʻano molekala CH₃COOH. Ua like kona molekala me kahi "mea huakaʻi solo" me kahi hui waikawa hoʻokahi. ʻO kēia ʻokoʻa i ke ʻano molekala, e like me kā lākou "code genetic", e hoʻoholo ai i kahi moʻo o nā ʻokoʻa ʻano ma hope.

ʻO ka hōʻike pololei loa o kēia "ʻokoʻa genetic" ʻo ia ka ikaika waikawa.
ʻO ka waikawa oxalic kahi waikawa ikaika diprotic hiki ke hoʻohuihui i nā ion hydrogen i nā ʻanuʻu i loko o ka hopena wai, e hoʻoikaika nui ana i kona waikawa ma mua o ka waikawa acetic.

He waikawa nāwaliwali monoprotic maʻamau ka waikawa acetic; hoʻohuihui wale kekahi o kona mau mole i ka wai, e hopena ana i ka waikawa iki.
Hiki iā mākou ke noʻonoʻo i ka waikawa oxalic ma ke ʻano he kanaka ʻōpio ikaika a pane koke, ʻoiai ʻo ka waikawa acetic e like me kahi ʻelemakule akahai a mālama ʻia.

Ma ke ʻano o nā waiwai kemika, ma muli o ka pilina pololei o kāna mau hui carboxyl ʻelua, loaʻa i ka waikawa oxalic ka hiki ke hoʻemi ikaika. Hiki ke hoʻopau maʻalahi ʻia e nā mea hoʻoemi (e like me ka potassium permanganate) e hana i ke kalapona dioxide a me ka wai. ʻO kēia ʻano e hoʻohana pinepine ʻia ai ka waikawa oxalic ma ke ʻano he mea hoʻemi i ka nānā ʻana i nā kemika.

I ka hoʻohālikelike ʻana, ʻo ke ʻano molekala o ka waikawa acetic he paʻa loa ia, ʻaʻole maʻalahi ka oxidized, e hāʻawi ana iā ia i kahi ʻano kemika "paʻa".
Eia kekahi, ke hana ka waikawa oxalic me kekahi mau iona metala (e like me nā iona calcium), hana ia i nā precipitates calcium oxalate i hoʻoheheʻe maikaʻi ʻole ʻia i ka wai, ʻo ia kekahi o nā ʻāpana nui o nā pōhaku puʻupaʻa.
I ka hoʻohālikelike ʻana, ʻo nā acetates i hoʻokumu ʻia e ka hopena o ka waikawa acetic me nā ion calcium a me nā mea ʻē aʻe he maʻalahi ke hoʻoheheʻe ʻia i ka wai.

Ma ke ʻano o ka hana a me ka hoʻohana ʻana, loaʻa i kēlā me kēia mea kona ʻano ponoʻī.
Loaʻa nui ka waikawa Oxalic i nā mea kanu he nui ma ke ʻano, e like me ka spinach, amaranth, a me ka rhubarb. ʻO ia ke kumu e ʻōlelo ʻia ai e hoʻomaʻemaʻe i kēia mau mea kanu ma mua o ka ʻai ʻana e wehe i kahi hapa o ka waikawa oxalic. Loaʻa iā ia kahi ākea o nā noi ʻoihana, me ka wehe ʻana i ka popo, ka hoʻokeʻokeʻo ʻana i nā lole, a me ka hoʻokaʻawale ʻana a me ka hoʻomaʻemaʻe ʻana i nā metala honua kakaikahi. Eia nō naʻe, ma muli o kona ʻawaʻawa a me ka palaho, pono e mālama pono i ka wā e hoʻohana ai.

ʻO ka waikawa acetic kekahi o nā waikawa organik i kamaʻāina loa i ke ola o kēlā me kēia lā. ʻO ia ka ʻāpana nui o ka vīnega, e hāʻawi ana i ka vīnega i kona ʻono ʻawaʻawa kū hoʻokahi. I ka ʻoihana meaʻai, hoʻohana ʻia ka waikawa acetic ma ke ʻano he acidulant a me ka preservative; i ka ʻoihana kemika, he mea maka synthesis organik koʻikoʻi ia no ka hana ʻana i ka vinyl acetate, nā fibers acetate, a me nā mea hou aku. Ma muli o kona acidity akahai a me ka haʻahaʻa loa o ka toxicity (i loko o nā pae hoʻohana kūpono), hoʻohana nui ʻia ka waikawa acetic a palekana hoʻi i nā kahua meaʻai a me nā lāʻau lapaʻau.

ʻAkika Oxalic – Zibo Anhao Chemical Co., Ltd.
ʻO Zibo Anhao Chemical Co., Ltd. kahi mea hana Kina hilinaʻi a me ka mea hoʻolako i ka waikawa oxalic kiʻekiʻe (Ethanedioic Acid, CAS 144-62-7), i hoʻokumu pono ʻia ma Zibo, Shandong—ka puʻuwai o ka ʻoihana kemika o Kina. Loaʻa kā mākou waikawa oxalic i nā ʻano anhydrous (≥99.5%) a me dihydrate (≥99.0%), e ʻike ʻia ana he pauka crystalline keʻokeʻo me nā waiwai kemika paʻa, ka makū haʻahaʻa, a me nā haumia liʻiliʻi.

Hana ʻia ma lalo o ka kaohi koʻikoʻi o ka maikaʻi a me nā kūlana aupuni, hōʻike kā mākou waikawa oxalic i ka mana hoʻemi ikaika a me ka hiki ke chelating maikaʻi loa, i hoʻohana nui ʻia i ka hoʻoluʻu lole (mordant/bleaching), ka mālama ʻana i ka metala (wehe ʻana i ka popo/electroplating), ka unuhi ʻana i ka honua laha ʻole, ka synthesis organik, ka ʻili ʻili, a me ka hana lāʻau lapaʻau a me ka mahiʻai. Ua hoʻāʻo piha ʻia kēlā me kēia pūʻulu a ua hele pū ʻia me COA, MSDS, a me nā palapala hoʻokō ʻē aʻe e hoʻokō i nā koi ʻoihana honua.

Me nā makahiki o ka ʻike hoʻokuʻu aku ma ʻAsia, ʻEulopa, ka Hikina Waena, a ma ʻō aku, hāʻawi mākou i ka ʻōpala maʻalahi (nā ʻeke 25kg), nā kumukūʻai hoʻokūkū, a me nā huaʻōlelo hoʻouna hilinaʻi (FOB/CIF/DDP). Inā no nā kauoha hoʻāʻo liʻiliʻi a i ʻole ka lako nui, hāʻawi ʻo Zibo Anhao Chemical i ka maikaʻi mau, ka lako paʻa, a me nā hoʻonā i hana kūikawā ʻia e kākoʻo i ka ulu ʻana o kāu ʻoihana.
