Ngā Āhuatanga Hanganga Ngota o te Waikawa Oxalic

Ko te hanganga ngota o te waikawa oxalic te pūtake o ōna āhuatanga matū. I roto i te hanganga, ko te waikawa oxalic he mea hanga mai i ngā rōpū carboxyl e rua (-COOH) e hono tika ana tetahi ki tetahi, ka taea te whakaatu i tēnei mā te tātai whakapoto HOOC-COOH. Ko ia rōpū carboxyl he mea hanga mai i te rōpū carbonyl (C=O) me te rōpū hydroxyl (-OH), he hanganga e hoatu ana ki te waikawa oxalic ngā āhuatanga noa o te waikawa dicarboxylic.

I roto i te āhua tioata, ka hangaia e ngā ngota waikawa oxalic tētahi whakaritenga motuhake mā te hononga hauwai. E whakaatu ana ngā rangahau hihi-X kei roto i ngā āhua tioata e rua te waikawa oxalic korewai: te āhua-α (ngā tioata rhombic) me te āhua-β (pūnaha monoclinic). Ka hangaia e te waikawa oxalic kua waikore he hanganga monoclinic, ka hangaia e ngā ngota wai me ngā ngota waikawa oxalic he whatunga hononga hauwai matatini. Mā tēnei āhuatanga hanganga ka ngaro tuatahi te wai tioata o ngā tioata waikawa oxalic ina werahia.

Mai i te tirohanga hanganga hiko, ko te āhua waikura o ngā ngota waro i roto i te waikawa oxalic he +3, he āhua uara waenga. Mā tēnei ka hoatu ki te waikawa oxalic ētahi āhuatanga waikura me ngā āhuatanga whakaiti nui, me ngā āhuatanga whakaiti e tino kaha ana i roto i te nuinga o ngā tauhohenga mahi. I roto i te ngota, ko te roa o te here waro-waro he 1.54 Å, ko te here takirua waro-hāora he 1.20 Å, ā, ko te here kotahi waro-hāora he 1.31 Å. E whakaata ana ēnei raraunga roa here i te tohatoha irahiko i roto i te ngota.

Ka tukuna e Zibo Anhao Chemical Co., Ltd. te Waikawa Oxalic kounga teitei (Waikawa Ethanedioic, CAS 144-62-7 anhydrous / 6153-56-6 dihydrate) — te waikawa dicarboxylic māmā rawa atu me te tātai ngota ngota (COOH)₂, e whakaatu ana i te 99.6% te parakore iti rawa me te kakano tioata pumau. I hangaia mā roto i ngā tukanga whakahāngaitanga konutai formate kua arotauhia, ko tā mātou waikawa oxalic he totoka tioata ma, kore kakara, he tino wairewa ki te wai me te etanoru, he kaha te whakaiti me te kaha whakakaha whakarewa tino pai. Ka tukuna e mātou ngā momo anhydrous me te dihydrate, kua takaihia ki roto i ngā putea whatu 25kg me ngā raina o roto, ngā putea IBC 1000kg rānei, kua whakaritea mō te horoi ahumahi, te tae kakahu, te maimoatanga mata whakarewa, me ngā tono hanganga rauropi. Ko te QC pakari o roto me ngā tuhinga tutuki katoa (COA, MSDS, REACH) ka whakamana i te kounga pumau mō ngā kaihoko o te ao. Hei kaihanga pono o te waikawa oxalic i Haina, ka whakakotahi mātou i ngā utu whakataetae, ngā rahinga ota ngāwari, me te tautoko ratonga pono hei whakakaha i ō mahi ahumahi puta noa i te ao.
