Soo saaraha Qiimaha Wanaagsan ee Oxalic Acid CAS: 144-62-7 Sawirka Sifaysan

sharaxaad gaaban:

Oxalic acid waa dicarboxylic acid xoog leh oo ku dhacda dhir iyo khudaar badan, badiyaa sida kalsiyumka ama cusbada potassium.Oxalic acid waa xarunta kaliya ee suurtogalka ah ee laba kooxood oo karboksyl ah ay si toos ah ugu biiraan;Sababtaas awgeed oxalic acid waa mid ka mid ah acids organic ugu xooggan.Si ka duwan asiidhyada karboksilic ee kale (marka laga reebo formic acid), si sahal ah ayaa oksaydhaysan loo sameeyaa;Tani waxay ka dhigaysaa mid waxtar u leh sidii wakiilka yaraynta sawir qaadista, bleaching, iyo ka saarista khad.Oxalic acid waxaa badanaa lagu diyaariyaa kuleylinta sodium hydroxide oo leh sodium hydroxide si loo sameeyo sodium oxalate, taas oo loo beddelo oxalate calcium waxaana lagu daaweeyaa sulfuric acid si loo helo oxalic acid bilaash ah.
Heerarka oxalic acid aad bay ugu hooseeyaan inta badan dhirta iyo cuntooyinka dhirta ku salaysan, laakiin waxaa ku filan isbinaajka, chard iyo cagaarka dabocase si ay u farageliyaan nuugista calcium ee dhirtaas sidoo kale ku jira.
Waxaa lagu soo saaraa jirka iyada oo loo marayo dheef-shiid kiimikaad glycoxylic acid ama ascorbic acid.Lama dheefi karo ee waxa ay ka soo baxdaa kaadida.Oxalic acid waa acaricide-dabiici ah oo loo isticmaalo daawaynta caarada varroa ee gumeysiga aan lahayn/hooseeya, baakado, ama raxan.Acid oxalic uumi ah ayay qaar ka mid ah beeralayda shinnidu u adeegsadaan cayayaan ka dhan ah caarada Varroa.

Guryaha Kiimikada:Oxalic acid waa budo aan ur lahayn, ama midab adag.Qaabka anhydrous (COOH)2 waa ur aan ur lahayn, adag oo cad;xalku waa dareere aan midab lahayn.

Codsiyada Oxalic acid

1. Oxalic acid waxaa inta badan loo isticmaali karaa sida hoos u dhigista wakiilka iyo warankiilada, mordant ee midabaynta iyo warshadaha daabacaadda, sidoo kale loo isticmaalo sifaynta biraha dhif ah, synthesis of oxalate ester amide kala duwan, oxalate iyo cawska, iwm.

2. Loo isticmaalo sida falanqeeye falanqeeye.

3. Loo isticmaalo sidii reagents shaybaadhka, reagents falanqaynta chromatography, dhex dhexaadinta dheeha iyo walxaha caadiga ah.

4. Oxalic acid waxaa inta badan loo isticmaalaa soo saarida dawooyinka sida antibiyootiga iyo borneol iyo dareeraha laga soo saaro birta dhifka ah, yaraynta dheeha iyo dheeha, maqaarka, iwm. ester, oxalate, iyo oxamide oo leh diethyl oxalate, sodium oxalate iyo calcium oxalate oo leh waxsoosaarka ugu badan.Oxalate waxa kale oo loo isticmaali karaa soo saarida cobalt-molybdenum-alumina kicinta, nadiifinta birta iyo marmarka iyo sidoo kale nadiifinta dunta.

Isticmaalka Beeraha:Oxalic acid, (COOH) 2, oo sidoo kale loo yaqaan ethanedioic acid, waa cad, adag oo crystalline ah, wax yar oo biyaha ku milmaya.Waa unug dabiici ah oo si dabiici ah u soo baxa oo oksaydhaysan oo leh firfircooni firfircoon.Waa mid aad u acidic ah oo sun ah, oo ay soo saaraan dhir badan sida sorrel (sourwood), caleemaha caleenta ee rhubarb, jilif eucalyptus iyo xididdo badan oo geedo ah.Unugyada dhirta iyo unugyada, oxalic acid waxay ku ururaan sida sodium, potassium ama calcium oxalate, kuwaas oo kan dambe u dhaco sida crystals.Dhanka kale, milixyada oxalic acids waxay galaan jidhka xayawaanka iyo bini'aadamka, taas oo keenta cilladaha cudurada, taas oo ku xidhan qadarka la isticmaalo.Noocyo badan oo fangaska ah sida Aspergillus, Penicillium, Mucor, iyo sidoo kale qaar ka mid ah lichens iyo caaryada slime waxay soo saaraan crystals oxalate calcium.Marka ay dhintaan microorganisms-kan, dhirta iyo xayawaanka, milixdu waxay ku sii daayaan ciidda, taasoo keenta xaddi sun ah.Si kastaba ha noqotee, microbes-ka-xumeeya, oo loo yaqaan 'Oxalobacter formigenes', waxay yareeyaan nuugista oxalate ee xayawaanka iyo bini'aadamka.

Oxalic acid waa kan ugu horreeya ee taxanaha dicarboxylic acids.Waxaa loo isticmaalaa (a) sida warankiilo wasakhda sida miridhku ama khad, (b) wax soo saarka dunta iyo hargaha, iyo (c) sida monoglyceryl oxalate ee soo saarida ally1 khamriga iyo formic acid.
