Oxalic acidwaa walax dabiici ah. Foomka kiimikada waa H₂c₂o₄. Waa wax soo saar dheef-shiid kiimikaad oo noolaha ah. Waa aashitada laba-qayb ah oo daciif ah. Waxaa si ballaaran loogu qaybiyaa geedka, xayawaanka, iyo xubnaha fangaska. Waxay ku shaqaysaa howlo kala duwan oo ku saabsan noolaha kala duwan ee nool. Sidaa darteed, aashitada oxalic waxaa badanaa loo arkaa inay ka hortagto nuugista iyo ka-faa'iideysiga waxyaabaha macdanta. Anhydigrid waa kaarboon kaadhsado.
Astaamaha:Xaashi aan midab lahayn oo aan lahayn ama qashin qubka ama budada cad, oxalic acid okless by okces, dhadhanka aashitada ee oxalic ee isku-darka. Ku-soo-nooleyntii 150 ~ 160 ℃. Waxaa laga yaabaa in lagu raadiyo hawo kulul oo kulul. 1G waxay ku milmaysaa 7Ml biyo, 2ml biyo karkaraya, 2.5ml ethanol, 1.8ml ethanol, oo ah 100ml etherce, oo ah 5.5ml etherrin, oo ay ku dhex jiraan Benzene, Chloroform iyo Batroolka. 0.1mol / L xalka wuxuu leeyahay pH oo 1.3 ah. Cufnaanta qaraabada (biyaha = 1) waa 1.653. Meesha dhalaalaysa 189.5 ℃.
Guryaha kiimikada:Oxlic acid, oo sidoo kale loo yaqaan aashitada glycolic, waxaa si weyn looga helaa cuntooyinka dhirta. Oxlic acid waa isku-darka midab leh oo midab leh, oo biyo ku dhex jira halkii laga isticmaali lahaa solvents dabiici ah sida ether,
Oxaalate wuxuu leeyahay saameyn xoog leh oo isku-dubbaridid oo kale ah oo ah nooc kale oo bir ah oo ka mid ah wakiilka birta ee cuntada dhirta. Marka ay aashito oxelic ah lagu daro qaar ka mid ah walxaha alkaline ee alkaline, xalideeda si weyn hoos ayaa loo dhimay, sida kaalshiyamka ah ee oxalaate ah ayaa ku dhawaad biyo ku dhex jira. Sidaa darteed, jiritaanka Oxlic acid waxay saameyn weyn ku leedahay bioavafal-ka macdanta muhiimka ah; Marka ay aashito oxelic ay weheliso qaar ka mid ah walxaha birta ku meel gaarka ah, dhismayaasha milatarta ayaa loo sameeyay ficil isuduwidda oo ay sabab u tahay oxalic acid, iyo xaruudahooda si weyn ayaa loo kordhiyaa.
Oxlic acid ayaa ku kalifay inay ku qubeysato 100 ℃, si dhakhso ah ugu dubay 125 ℃, oo si aad ah u dubbaday 157 ℃, oo bilaabay inuu burburiyo.
Waxay ka falcelin kartaa alkali, waxay soo saari kartaa edbinta, cadeynta Acyl Halogention, falcelin ahaan. Falcelinta yareynta ayaa waliba dhici kartaa, iyo falcelinta decarxuleation waxay ku dhici kartaa kuleylka. ADHYDRUSDHODE ACIONIC Acid waa hygroscopic. Oxlic acid waxay ka dhigan tahay dhismayaasha biyaha-milmi-ku-dhaca birta badan.
Oxi obilii ah:1, Sodium oksiotate; 2, potassinate; 3, kaalshiyaye oxalate; 4, oxiousk. 5, dibi-xummad; 6, ammonium hydrogen oxalite; 7, Magnesium oksiolate 8, lithium oxoatate.
