Waikawa Oxaliche matū waro.Ko te ahua matū ko H₂C₂O₄.He hua metabolic o nga rauropi.He waikawa ngoikore nga wahanga e rua.Ka tohatohahia ki nga tipu, kararehe, me nga tinana harore.He maha nga mahi i roto i nga momo rauropi.Na reira, ka kiia ko te waikawa oxalic he kaipatu mo te whakauru me te whakamahi i nga huānga kohuke.Ko tana anhydride he waro trioxide.
Āhuatanga:Pepa monoclinic taekore, karaihe prismatic, paura ma ranei, waikawa oxalic kaore he kakara ma te waiora, te reka o te waikawa oxalic ma te whakahiato.Te whakaheke i te 150 ~ 160 ℃.Ka taea te whakamaua i te hau maroke wera.He wairewa te 1g ki te wai 7mL, 2mL wai koropupu, 2.5mL waiwaro, 1.8mL waiwaro koropupu, 100mL etera, 5.5mL glycerin, karekau e rewa ki te benzene, chloroform me te hinu etere.Ko te wairewa 0.1mol/L he pH 1.3.Ko te kiato whanaunga (wai =1) he 1.653.Ira whakarewa 189.5 ℃.
Āhuatanga matū:Ko te waikawa Oxalic, e mohiotia ana ko te waikawa glycolic, ka kitea i roto i nga kai tipu.Ko te waikawa Oxalic he karaihe karekau he tae, he memeha ki te wai, kaua ki nga whakarewa pararopi penei i te ether,
He kaha te ruruku o te Oxalate, a, ko tetahi atu ahua o te maatete whakarewa i roto i nga kai tipu.Ka honoa te waikawa oxalic ki etahi mea whakarewa whenua kawakore, ka tino heke tona memehatanga, penei i te konupūmā oxalate he tata kore e rewa ki te wai.Na reira, ko te aroaro o te waikawa oxalic he painga nui ki te koiora o nga kohuke tino nui;Ka honoa te waikawa oxalic ki etahi huānga whakarewa whakawhiti, ka puta mai nga matatini whakarewa na te mahi ruruku o te waikawa oxalic, a ka tino piki ake te whakarewatanga.
I timata te waikawa Oxalic ki te whakaheke i te 100 ℃, ka tere te whakaheke i te 125 ℃, me te tino whakaheke i te 157 ℃, ka timata ki te pirau.
Ka taea te tauhohe ki te kawakore, ka taea te whakaputa esterification, te acyl halogenation, te tauhohenga amide.Ka puta ano nga tauhohenga whakaheke, ka puta ano nga tauhohenga decarboxylation i raro i te wera.Ko te waikawa oxalic anhydrous he hygroscopic.Ka hangaia e te waikawa Oxalic nga matatini wairewa-wai me nga konganuku maha.
Oxalate noa:1, konutai oxalate;2, konupora oxalate;3, konupora oxalate;4, Ferrous oxalate;5, Antimony oxalate;6, haukinia hauwai oxalate;7, Magnesium oxalate 8, Lithium oxalate.
