Àgwà Nhazi Molekụla nke Oxalic Acid

Nhazi molekul nke oxalic acid bụ ntọala nke ihe onwunwe kemịkalụ ya. N'usoro, oxalic acid nwere otu carboxyl abụọ (-COOH) ejikọtara onwe ha ozugbo, nke usoro a na-akpọ HOOC-COOH nwere ike ịnọchite anya ya. Otu carboxyl ọ bụla nwere otu carbonyl (C=O) na otu hydroxyl (-OH), usoro nke na-enye oxalic acid njirimara a na-ahụkarị nke dicarboxylic acid.

N'ọnọdụ kristal, molekul oxalic acid na-etolite nhazi pụrụ iche site na njikọ hydrogen. Ọmụmụ ihe gbasara mgbasa ozi X-ray na-egosi na anhydrous oxalic acid dị n'ụdị kristal abụọ: ụdị α (crystals rhombic) na ụdị β (usoro monoclinic). Acid oxalic dihydrated na-emepụta usoro monoclinic, ebe molekul mmiri na molekul oxalic acid na-etolite netwọk njikọ hydrogen dị mgbagwoju anya. Njirimara nhazi a na-akọwa ihe kpatara kristal oxalic acid ji efunahụ mmiri kristal ha na mbụ mgbe a na-ekpo ọkụ.

Site n'echiche nhazi eletrọnịkị, atọm carbon dị na oxalic acid nwere ọnọdụ oxidation nke +3, ọnọdụ valence dị n'etiti. Nke a na-enye oxalic acid ma ụfọdụ ihe ndị na-eme ka oxidation dị na ihe ndị dị mkpa na-ebelata ihe, yana mbelata ihe ndị na-achịkwa ọtụtụ mmeghachi omume bara uru. Na molekul ahụ, ogologo njikọ carbon-carbon bụ 1.54 Å, njikọ abụọ carbon-oxygen bụ 1.20 Å, na njikọ otu carbon-oxygen bụ 1.31 Å. Data ogologo njikọ ndị a na-egosipụta nkesa eletrọn n'ime molekul ahụ.

Zibo Anhao Chemical Co., Ltd. na-enye Oxalic Acid dị elu (Ethanedioic Acid, CAS 144-62-7 anhydrous / 6153-56-6 dihydrate) — dicarboxylic acid kachasị mfe nwere usoro molekul (COOH)₂, nke nwere 99.6% ịdị ọcha kacha nta na udidi kristal na-agbanwe agbanwe. Ejiri usoro oxidation sodium formate eme ihe, oxalic acid anyị bụ kristal ọcha, nke na-enweghị isi, nke a na-agbaze nke ukwuu na mmiri na ethanol, yana ihe onwunwe na-ebelata ike yana ikike chelating metal pụrụ iche. Anyị na-enye ma ọkwa anhydrous na dihydrate, nke a na-etinye na akpa 25kg nke nwere ihe mkpuchi dị n'ime ma ọ bụ akpa IBC 1000kg, nke ahaziri maka nhicha ụlọ ọrụ mmepụta ihe, agba ákwà, ọgwụgwọ elu ígwè, na mkpa njikọ organic. QC siri ike n'ime ụlọ na akwụkwọ nrubeisi zuru oke (COA, MSDS, REACH) na-ekwe nkwa ịdị mma kwụsiri ike maka ndị na-azụ ahịa ụwa. Dịka onye na-emepụta oxalic acid nke dị na China a pụrụ ịtụkwasị obi, anyị na-ejikọta ọnụ ahịa asọmpi, olu usoro mgbanwe, na nkwado njem njem a pụrụ ịdabere na ya iji kwalite ọrụ ụlọ ọrụ gị n'ụwa niile.
