Izici Zesakhiwo Se-Molecular ze-Oxalic Acid

Isakhiwo sama-molecule se-oxalic acid sakha isisekelo sezakhiwo zayo zamakhemikhali. Ngokwesakhiwo, i-oxalic acid yakhiwa amaqembu amabili e-carboxyl (-COOH) ahlanganiswe ngqo komunye nomunye, angamelwa yifomula ehlanganisiwe i-HOOC-COOH. Iqembu ngalinye le-carboxyl lakhiwe yiqembu le-carbonyl (C=O) kanye neqembu le-hydroxyl (-OH), isakhiwo esinikeza i-oxalic acid izici ezijwayelekile ze-dicarboxylic acid.

Esimweni sekristalu, ama-molecule e-oxalic acid akha uhlelo oluthile ngokubopha i-hydrogen. Izifundo ze-X-ray diffraction zibonisa ukuthi i-oxalic acid engamanzi ikhona ngezindlela ezimbili zekristalu: ifomu le-α (amakristalu e-rhombic) kanye nefomu le-β (uhlelo lwe-monoclinic). I-oxalic acid e-dihydrated yakha isakhiwo se-monoclinic, lapho ama-molecule amanzi nama-molecule e-oxalic acid akha inethiwekhi eyinkimbinkimbi yokubopha i-hydrogen. Lesi sici sesakhiwo sichaza ukuthi kungani amakristalu e-oxalic acid elahlekelwa amanzi awo okwakheka kwe-crystallization kuqala lapho eshiswa.

Ngokombono wesakhiwo se-elekthronikhi, ama-athomu e-carbon ku-oxalic acid anesimo se-oxidation esingu-+3, isimo se-valence esiphakathi. Lokhu kunikeza i-oxalic acid kokubili izakhiwo ezithile ze-oxidizing kanye nezakhiwo ezibalulekile zokunciphisa, kanye nezakhiwo zokunciphisa ezibusa kakhulu ekuphenduleni okusebenzayo. Ku-molecule, ubude besibopho se-carbon-carbon bungu-1.54 Å, isibopho esiphindwe kabili se-carbon-oxygen singu-1.20 Å, kanti isibopho esisodwa se-carbon-oxygen singu-1.31 Å. Le datha yobude besibopho ibonisa ukusatshalaliswa kwama-electron ngaphakathi kwe-molecule.

I-Zibo Anhao Chemical Co., Ltd. inikeza i-Oxalic Acid (i-Ethanedioic Acid, i-CAS 144-62-7 anhydrous / 6153-56-6 dihydrate) - i-dicarboxylic acid elula kakhulu enefomula yama-molecule (COOH)₂, equkethe ubumsulwa obuncane obungu-99.6% kanye nokuthungwa okuqinile kwekristalu. Yakhiwe ngezinqubo ze-oxidation ze-sodium formate ezilungiselelwe kahle, i-oxalic acid yethu iyi-crystalline eqinile emhlophe, engenaphunga, encibilika kakhulu emanzini nase-ethanol, enezakhiwo zokunciphisa ezinamandla kanye nekhono elihle kakhulu le-chelating yensimbi. Sihlinzeka ngama-anhydrous nama-dihydrate grades, apakishwe ezikhwameni ezilukiwe ezingama-25kg ezinama-inner liner noma ama-IBC totes angu-1000kg, aklanyelwe ukuhlanza kwezimboni, ukudaya izindwangu, ukwelashwa kobuso bensimbi, kanye nezidingo zokwenziwa kwezinto eziphilayo. I-QC eqinile yangaphakathi kanye nemibhalo egcwele yokuthobela imithetho (COA, MSDS, REACH) iqinisekisa ikhwalithi ezinzile kubathengi bomhlaba wonke. Njengomkhiqizi we-oxalic acid othembekile osekelwe eShayina, sihlanganisa amanani ancintisanayo, amanani oku-oda aguquguqukayo, kanye nokusekelwa okuthembekile kwe-logistics ukuze sikhuthaze imisebenzi yakho yezimboni emhlabeni jikelele.
