nkọwa dị mkpirikpi:

Oxalic acid bụ acid dicarboxylic siri ike nke na-apụta n'ọtụtụ osisi na akwụkwọ nri, nke a na-ahụkarị dịka nnu calcium ma ọ bụ potassium ya. Oxalic acid bụ naanị ihe nwere ike ime ka otu carboxyl abụọ jikọọ ozugbo; n'ihi nke a, oxalic acid bụ otu n'ime asịd organic kachasị ike. N'adịghị ka asịd carboxylic ndị ọzọ (ma e wezụga formic acid), a na-eme ka ọ dị ngwa ngwa; nke a na-eme ka ọ baa uru dị ka ihe na-ebelata foto, ịcha ọcha, na iwepụ ink. A na-akwadebekarị oxalic acid site na iji sodium hydroxide kpoo sodium formate iji mepụta sodium oxalate, nke a na-agbanwe ka ọ bụrụ calcium oxalate ma gwọọ ya na sulfuric acid iji nweta oxalic acid n'efu.
Oke oxalic acid dị obere n'ọtụtụ osisi na nri osisi, mana e nwere ọtụtụ ihe dị na akwụkwọ nri spinach, chard na beet iji gbochie mmịpụta calcium nke osisi ndị a nwekwara.
A na-emepụta ya n'ahụ site na metabolism nke glyoxylic acid ma ọ bụ ascorbic acid. A naghị emepụta ya na mmamịrị kama a na-ewepụ ya n'ime mmamịrị. A na-eji ya dị ka ihe nyocha na ihe na-ebelata ihe niile. Oxalic acid bụ acaricide eke nke a na-eji agwọ ọrịa varroa mites na mpaghara ndị nwere obere nwa, ngwugwu, ma ọ bụ ìgwè anụ. Ụfọdụ ndị na-azụ aṅụ na-eji oxalic acid nke a na-esi n'ọkụ eme ihe dị ka ọgwụ ahụhụ megide nje Varroa.

Njirimara Kemịkalụ:Oxalic acid bụ ntụ ntụ na-enweghị agba, enweghị isi, ma ọ bụ granular siri ike. Ụdị anhydrous (COOH)2 bụ ihe siri ike na-enweghị isi, ọcha; ngwọta ya bụ mmiri mmiri na-enweghị agba.

Ngwa nke Oxalic Acid

1. A pụrụ iji oxalic acid mee ihe dị ka ihe na-ebelata ihe na ihe na-eme ka ọbara dị ọcha, ihe na-eme ka agba na mbipụta akwụkwọ dị iche iche, a na-ejikwa ya eme ihe n'ịchacha ígwè dị iche iche, imepụta ụdị oxalate ester amide dị iche iche, oxalate na ahịhịa, wdg.

2. Ejiri ya mee ihe dịka ihe nyocha.

3. A na-eji ya eme ihe dị ka ihe ndị na-eme ka ihe dị n'ime ụlọ nyocha, ihe ndị na-eme ka ihe dị n'ime chromatography, ihe ndị na-eme ka agba dị n'etiti ihe na ihe ndị e ji eme ihe.

4. A na-ejikarị oxalic acid emepụta ọgwụ dịka ọgwụ nje na borneol na ihe mgbaze maka iwepụ ihe dị ụkọ, ihe na-ebelata ihe na agba, ihe na-eme ka akpụkpọ ahụ dị nro, wdg. Na mgbakwunye, enwere ike iji oxalic acid mepụta ụdị oxalate ester dị iche iche, oxalate, na oxamide yana diethyl oxalate, sodium oxalate na calcium oxalate nwere nnukwu mkpụrụ. A pụkwara iji oxalate mee ihe maka mmepụta nke cobalt-molybdenum-alumina catalyst, nhicha nke metal na marble yana ịcha ọcha nke ákwà.

Ojiji Ọrụ Ugbo:Oxalic acid, (COOH)2, nke a na-akpọkwa ethanedioic acid, bụ ihe siri ike ọcha, kristal, nke na-agbaze ntakịrị n'ime mmiri. Ọ bụ ihe mejupụtara organic nke e ji ihe ndị dị ndụ mee nke ọma nke nwere ọrụ chelating dị ukwuu. Ọ na-esi ike ma na-egbu egbu, nke ọtụtụ osisi dị ka sorrel (sourwood), akwụkwọ rhubarb, ogbugbo eucalyptus na ọtụtụ mgbọrọgwụ osisi na-emepụta. Na mkpụrụ ndụ osisi na anụ ahụ, oxalic acid na-agbakọta dị ka sodium, potassium ma ọ bụ calcium oxalate, nke ikpeazụ na-apụta dị ka kristal. N'aka nke ya, nnu nke oxalic acid na-abanye n'ahụ anụmanụ na mmadụ, na-akpata nsogbu ọrịa, dabere na ọnụọgụ e riri. Ọtụtụ ụdị fungi dị ka Aspergillus, Penicillium, Mucor, yana ụfọdụ lichens na slime ebu na-emepụta kristal calcium oxalate. Mgbe nje ndị a, osisi na anụmanụ nwụrụ, nnu ndị ahụ na-apụta n'ime ala, na-akpata ụfọdụ nsí. Agbanyeghị, nje ndị na-emebi oxalate, nke a na-akpọ Oxalobacter formigenes, na-ebelata nnabata oxalate n'ime anụmanụ na mmadụ.

Oxalic acid bụ nke mbụ n'ime usoro dicarboxylic acid. A na-eji ya (a) dị ka ihe na-eme ka agba dị ka nchara ma ọ bụ ink dị ọcha, (b) na mmepụta ákwà na akpụkpọ anụ, na (c) dị ka monoglyceryl oxalate na mmepụta nke ally1 alcohol na formic acid.
