Nā ʻano kūkulu molekala o ka waikawa Oxalic

ʻO ke ʻano molekala o ka waikawa oxalic ke kumu o kona mau waiwai kemika. Ma ke ʻano he ʻano, aia ka waikawa oxalic i ʻelua mau hui carboxyl (-COOH) i hoʻopaʻa pololei ʻia kekahi i kekahi, hiki ke hōʻike ʻia e ka formula i hoʻopaʻa ʻia ʻo HOOC-COOH. Ua haku ʻia kēlā me kēia hui carboxyl me kahi hui carbonyl (C=O) a me kahi hui hydroxyl (-OH), kahi ʻano e hāʻawi ana i ka waikawa oxalic i nā ʻano maʻamau o kahi waikawa dicarboxylic.

I ke kūlana crystalline, hoʻokumu nā molekala waikawa oxalic i kahi hoʻonohonoho kikoʻī ma o ka hoʻopili hydrogen. Hōʻike nā haʻawina diffraction X-ray aia ka waikawa oxalic anhydrous i ʻelua mau ʻano kristal: ke ʻano α (nā kristal rhombic) a me ke ʻano β (ʻōnaehana monoclinic). Hoʻokumu ka waikawa oxalic dihydrated i kahi ʻano monoclinic, kahi e hoʻokumu ai nā molekala wai a me nā molekala waikawa oxalic i kahi pūnaewele hoʻopili hydrogen paʻakikī. Hōʻike kēia hiʻohiʻona hoʻonohonoho i ke kumu e nalowale ai nā kristal waikawa oxalic i ko lākou wai o ka crystallization i ka wā e hoʻomehana ʻia ai.

Mai kahi kuanaʻike hoʻonohonoho uila, loaʻa i nā ʻātoma kalapona i loko o ka waikawa oxalic kahi kūlana oxidation o +3, kahi kūlana valence waena. Hāʻawi kēia i ka waikawa oxalic i kekahi mau waiwai oxidizing a me nā waiwai hōʻemi koʻikoʻi, me nā waiwai hōʻemi e noho aliʻi ana i ka hapa nui o nā hopena hana. I loko o ka molekala, ʻo ka lōʻihi o ka pilina kalapona-kalapona he 1.54 Å, ʻo ka pilina pālua kalapona-oxygen he 1.20 Å, a ʻo ka pilina hoʻokahi kalapona-oxygen he 1.31 Å. Hōʻike kēia mau ʻikepili lōʻihi o ka pilina i ka hoʻolaha ʻana o ka electron i loko o ka molekala.

Hāʻawi ʻo Zibo Anhao Chemical Co., Ltd. i ka Oxalic Acid kiʻekiʻe loa (Ethanedioic Acid, CAS 144-62-7 anhydrous / 6153-56-6 dihydrate) - ʻo ia ka dicarboxylic acid maʻalahi loa me ke ʻano molekala (COOH)₂, e hōʻike ana i ka maʻemaʻe liʻiliʻi he 99.6% a me ke ʻano crystalline kūlike. Hana ʻia ma o nā kaʻina hana oxidation sodium formate i hoʻomaikaʻi ʻia, ʻo kā mākou oxalic acid he crystalline paʻa keʻokeʻo, ʻala ʻole, hiki ke hoʻoheheʻe ʻia i ka wai a me ka ethanol, me nā waiwai hoʻemi ikaika a me ka hiki ke hoʻopili metala koʻikoʻi. Hāʻawi mākou i nā ʻano anhydrous a me dihydrate, i hoʻopili ʻia i loko o nā ʻeke ulana 25kg me nā liners o loko a i ʻole 1000kg IBC totes, i hana ʻia no ka hoʻomaʻemaʻe ʻoihana, ka hoʻoluʻu lole, ka mālama ʻana i ka ʻili metala, a me nā koi synthesis organik. ʻO ka QC paʻa i loko o ka hale a me nā palapala hoʻokō piha (COA, MSDS, REACH) e hōʻoiaʻiʻo i ka maikaʻi paʻa no nā mea kūʻai honua. Ma ke ʻano he mea hana waikawa oxalic hilinaʻi ma Kina, hoʻohui mākou i nā kumukūʻai hoʻokūkū, nā nui kauoha maʻalahi, a me ke kākoʻo logistics hilinaʻi e hoʻoulu i kāu mau hana ʻoihana ma ka honua holoʻokoʻa.
