Soo-saare Qiimo Fiican Oxalic Acid CAS: 144-62-7

sharraxaad gaaban:

Asiidhka Oxalic waa asiidh dicarboxylic ah oo xooggan oo ka dhaca dhir iyo khudaar badan, badanaa sida cusbada kaalshiyamka ama potassium-ka. Asiidhka Oxalic waa isku-dhafka kaliya ee suurtogalka ah ee laba kooxood oo carboxyl ah si toos ah isugu xidhmaan; sababtaas awgeed asiidhka oxalic waa mid ka mid ah asiidhyada ugu xooggan ee dabiiciga ah. Si ka duwan asiidhyada kale ee carboxylic (marka laga reebo asiidhka formic), si fudud ayaa loo oksaydhiyaa; tani waxay ka dhigaysaa mid waxtar u leh sidii wakiil yareeya sawir-qaadista, cadaynta, iyo ka saarista khad. Asiidhka Oxalic waxaa badanaa lagu diyaariyaa iyadoo lagu kululaynayo sodium formate sodium hydroxide si loo sameeyo sodium oxalate, kaas oo loo beddelo calcium oxalate oo lagu daweeyo sulfuric acid si loo helo oxalic acid bilaash ah.
Xoogagga oxalic acid aad bay ugu yar yihiin dhirta badankood iyo cuntooyinka ku salaysan dhirta, laakiin waxaa ku filan isbinaajka, chard iyo cagaarka beet si ay u farageliyaan nuugista kalsiyum-ka dhirtaas ku jira.
Waxaa lagu soo saaraa jirka iyadoo la adeegsanayo dheef-shiid kiimikaadka glyoxylic acid ama ascorbic acid. Lama dheefshiido laakiin waxaa lagu soo saaraa kaadida. Waxaa loo isticmaalaa falanqayn iyo wakiil guud oo yareeya. Aashitada Oxalic waa acaricide dabiici ah oo loo isticmaalo daaweynta caarada varroa ee deegaannada aan lahayn/hooseeya ee digaagga, baakadaha, ama kooxaha. Aashitada oxalic ee uumiga leh waxaa isticmaala qaar ka mid ah kuwa shinnida dhaqda si ay u disho cayayaanka Varroa ee dulinka ah.

Sifooyinka Kiimikada:Asiidhka Oxalic waa budo aan midab lahayn, aan ur lahayn, ama budo adag. Qaabka aan biyaha lahayn (COOH)2 waa mid aan ur lahayn, cad oo adag; xalku waa dareere aan midab lahayn.

Isticmaalka Oxalic Acid

1. Aashitada Oxalic waxaa inta badan loo isticmaali karaa sidii wakiilka yareeya iyo wakiilka cadayga, waxaa loo isticmaali karaa rinjiyeynta iyo warshadaha daabacaadda, sidoo kale waxaa loo isticmaalaa sifeynta birta dhifka ah, sameynta noocyada kala duwan ee oxalate ester amide, oxalate iyo cawska, iwm.

2. Waxaa loo isticmaalaa sidii falanqayn falanqayn ah.

3. Waxaa loo isticmaalaa sidii reagents shaybaar, reagents falanqaynta koromatografi, dhexdhexaadinta rinjiga iyo walxaha caadiga ah.

4. Asiidhka Oxalic waxaa inta badan loo isticmaalaa soo saarista daawooyinka sida antibiyootikada iyo borneol iyo dareeraha lagu soo saaro birta naadirka ah, wakiilka yareeya iyo rinjiga, wakiilka midabaynta, iwm. Intaa waxaa dheer, asiidhka oxalic waxaa sidoo kale loo isticmaali karaa isku-darka noocyada kala duwan ee oxalate ester, oxalate, iyo oxamide oo leh diethyl oxalate, sodium oxalate iyo calcium oxalate oo leh wax-soo-saarka ugu badan. Oxalate waxaa sidoo kale loo isticmaali karaa soo saarista kobalt-molybdenum-alumina catalyst, nadiifinta birta iyo marmarka iyo sidoo kale cadaynta dharka.

Isticmaalka Beeraha:Asiidhka Oxalic, (COOH)2, oo sidoo kale loo yaqaan ethanedioic acid, waa cad, adag oo crystalline ah, oo si yar ugu milma biyaha. Waa isku-dhis dabiici ah oo si dabiici ah u oksaydhsan oo leh firfircooni chelating oo muhiim ah. Waa mid aad u aashito badan oo sun ah, oo ay soo saaraan dhir badan sida sorrel (sourwood), daabyada caleenta rhubarb, jilif eucalyptus iyo xididdo badan oo dhir ah. Unugyada dhirta iyo unugyada, asiidhka oxalic wuxuu ku ururaa sodium, potassium ama calcium oxalate, kaas oo kan dambe uu u dhaco sida kiristaal. Dhanka kale, milixda asiidhka oxalic waxay gashaa jidhka xayawaanka iyo aadanaha, taasoo keenta xanuuno cudur, iyadoo ku xiran inta la cuno. Noocyo badan oo fangaska ah sida Aspergillus, Penicillium, Mucor, iyo sidoo kale qaar ka mid ah lichens iyo caaryada slime waxay soo saaraan kiristaallada calcium oxalate. Marka ay dhintaan noolahaan, dhirta iyo xayawaanka, milixda ayaa lagu sii daayaa ciidda, taasoo keenta sun. Si kastaba ha ahaatee, microbes-ka burburiya oxalate, oo loo yaqaan Oxalobacter formigenes, waxay yareeyaan nuugista oxalate ee xayawaanka iyo aadanaha.

Asiidhka Oxalic waa kan ugu horreeya ee taxane ah asiidhyada dicarboxylic. Waxaa loo isticmaalaa (a) sidii wakiil cadaya wasakhda sida miridhku ama khad, (b) wax soo saarka dharka iyo maqaarka, iyo (c) sida monoglyceryl oxalate marka la soo saarayo asiidhka ally1 iyo formic.
