Imiterere ya aside oxalic mu miterere ya molekile

Imiterere ya molekile ya aside oxalic ni yo shingiro ry'imiterere yayo ya shimi. Mu miterere, aside oxalic igizwe n'amatsinda abiri ya karubokisili (-COOH) afatanye mu buryo butaziguye, ashobora gugaragazwa na formula ifunze ya HOOC-COOH. Buri tsinda rya karubokisili rigizwe n'itsinda rya karubokisili (C=O) n'itsinda rya hydroxyl (-OH), imiterere iha aside oxalic imiterere isanzwe ya aside dicarboksilili.

Mu gihe cy’ubucukumbuzi, molekile za aside oxalic zigira uburyo bwihariye binyuze mu guhuza hydrogen. Ubushakashatsi bwa X-ray bugaragaza ko aside oxalic anhydrous iboneka mu buryo bubiri bwa kristu: α-form (rombic crystals) na β-form (monoclinic system). Aside oxalic dihydrate ikora imiterere ya monoclinic, aho molekile z’amazi na molekile za aside oxalic zigira urusobe rw’imibanire ya hydrogen. Iyi miterere isobanura impamvu kristu za aside oxalic zitakaza amazi yazo yo guhuza crystallization mbere yo gushyuha.

Ukurikije imiterere y'ikoranabuhanga, atome za karuboni muri aside oxalic zifite imiterere ya oxidation ya +3, imiterere ya valence iri hagati. Ibi biha aside oxalic imiterere imwe n'imwe yo oxidation n'imiterere ikomeye yo kugabanya, hamwe n'imiterere yo kugabanya ikaba ari yo iganza mu bikorwa byinshi. Muri molekile, uburebure bw'umugozi wa karuboni na karuboni ni 1.54 Å, umugozi wa karuboni na ogisijeni ni 1.20 Å, naho umugozi umwe wa karuboni na ogisijeni ni 1.31 Å. Aya makuru y'uburebure bw'umugozi agaragaza ikwirakwizwa rya electron muri molekile.

Zibo Anhao Chemical Co., Ltd. itanga aside ya Oxalic yo mu rwego rwo hejuru (aside Ethanedioic, CAS 144-62-7 anhydrous / 6153-56-6 dihydrate) - aside dicarboxylic yoroshye cyane ifite formula ya molekile (COOH)₂, ifite ubuziranenge bungana na 99.6% n'imiterere ihoraho ya kristale. Ikozwe binyuze mu buryo bworoshye bwa oxidation ya sodium formate, aside oxalic yacu ni crystalline solid yera, idahumura, ishongesha cyane mu mazi na ethanol, ifite imiterere ikomeye yo kugabanya kandi ikagira ubushobozi budasanzwe bwo gukaraba ibyuma. Dutanga aside ya anhydrous na dihydrate, ipakiye mu mifuka ya 25kg iboshye irimo imigozi y'imbere cyangwa 1000kg IBC totes, igenewe gusukurwa mu nganda, gusiga amarangi mu myenda, gutunganya icyuma, no gukenera gukora organic synthesis. QC ikomeye mu nzu hamwe n'inyandiko zuzuye zo kubahiriza amategeko (COA, MSDS, REACH) bitanga ubuziranenge buhamye ku baguzi ku isi. Nk'umucuruzi wizerwa w'aside oxalic ukorera mu Bushinwa, duhuza ibiciro bishimishije, ingano y'ibicuruzwa byoherezwa mu buryo bworoshye, hamwe n'inkunga yizewe yo gutwara ibintu kugira ngo dutere imbaraga ibikorwa byawe by'inganda ku isi yose.
