Oxalic acid bụ ihe organic nwere usoro kemịkalụ H₂C₂O₄.Ọ bụ metabolite nke ihe ndị dị ndụ.Ọ bụ acid na-adịghị ike.A na-ekesa ya na osisi, anụmanụ na fungi, ma na-arụ ọrụ dị iche iche n'ụdị dị iche iche.Anhydride acid ya bụ carbon trioxide.Ọdịdị nke oxalic acid bụ flake monoclinic na-enweghị agba ma ọ bụ kristal prismatic ma ọ bụ ntụ ntụ ọcha, enweghị isi, uto utoojoo, na-adị mfe soluble na mmiri mana ọ naghị agbaze na ihe mgbaze organic dị ka ether.Arọ molekụla nke oxalic acid bụ 90.0349.
Ojiji nke oxalic acid: onye na-eme mgbagwoju anya, onye na-ekpuchi ihe mkpuchi, onye na-emepụta ihe, onye na-ebelata ihe.
1, dị ka onye na-ahụ maka ịcha ọcha
A na-ejikarị oxalic acid dị ka onye na-ebelata ihe na-eme ka ọ dị ọcha na ihe na-acha ọcha, nke a na-eji na-emepụta ọgwụ ndị dị ka ọgwụ nje na borneol, dị ka ihe mgbaze maka mmịpụta nke ọla ndị na-adịghị ahụkebe, dị ka ihe na-ebelata agba agba, na ihe na-eme ka akpụkpọ anụ.
A na-ejikwa oxalic acid na-emepụta cobalt-molybdenum-aluminom catalysts, ihicha ọla na marble, na ịcha ọcha nke textiles.
2. Dị ka onye na-ebelata ego
N'ime ụlọ ọrụ mmepụta ihe, a na-ejikarị emepụta ngwaahịa kemịkal dị ka hydroquinone, pentaerythritol, cobalt oxalate, nickel oxalate, na gallic acid.
A na-eji ụlọ ọrụ plastik mee ihe na mmepụta nke polyvinyl chloride, aminoplastics, urea-formaldehyde plastics, lacquer sheets, wdg.
A na-eji ụlọ ọrụ na-esiji eme ihe n'ịmepụta magenta green, wdg.
Na ụlọ ọrụ obibi akwụkwọ na ịcha akwa, ọ nwere ike dochie acetic acid ma jiri ya mee ihe dị ka ihe enyemaka na-emepe emepe agba na ihe ịcha ọcha maka agba agba.
A na-eji ụlọ ọrụ na-emepụta ọgwụ na-emepụta chlortetracycline, oxytetracycline, tetracycline, streptomycin, na ephedrine.
Tụkwasị na nke ahụ, a pụkwara iji oxalic acid mee ihe dị iche iche dị ka oxalate, oxalate na oxalamide, n'ime nke diethyl oxalate, sodium oxalate na calcium oxalate kachasị na-arụpụta.
3. Dị ka onye ndu
Enwere ike iji Antimony oxalate mee ihe dị ka mordant, na ferric ammonium oxalate bụ onye nnọchi anya maka ibipụta blueprints.
4 Ọrụ iwepụ ajari
Enwere ike iji oxalic acid wepụ nchara: zụta karama oxalic acid n'ụlọ ahịa na-ere ọgwụ reagents, were ụfọdụ, mee ihe ngwọta na mmiri ọkụ, tinye ya na nchara nchara wee hichaa ya.(Rịba ama: Kpachara anya mgbe ị na-eji ya, oxalic acid na-emebi emebi nke ukwuu na igwe anaghị agba nchara. Oxalic acid nwere oke itinye uche na-adịkwa mfe imebi aka. Na acid oxalate emepụtara na-agbaze nke ukwuu, mana ọ nwere ụfọdụ nsí. Erila ya. Mgbe a na-eji . Mgbe akpụkpọ ahụ batara na oxalic acid, a ga-eji mmiri saa ya n'oge.)
Oxalic acid nchekwa
1. Na-echekwa na akọrọ na jụụ ebe.Igwe anaghị agba nchara, mkpuchi mmiri, mkpuchi anwụ.Okpomọkụ nchekwa ekwesịghị gafere 40 ℃.
2. Na-ezere oxides na alkaline bekee.Ejiri ya na akpa rọba kpuchie akpa polypropylene.
