Oxalic acid

AKWỤKWỤKWỌ CHINEKE

A na-ekesa acid oxalic n'ọtụtụ ebe na osisi na okike, ọtụtụ dị n'ụdị nnu oxalic acid. CW Scheele nwere nke mbụ emepụtara oxalate na 1776.

Oxalate bụ acid kachasị ike n'etiti acid dicarboxylic. E wezụga inwe njiri mara nke carboxylic acid, ọ na-ebelata ihe onwunwe ma nwee ike ibelata manganese valence asaa n'ụzọ dị ukwuu na manganese bivalent. A na-ejikarị ihe onwunwe a eme ihe maka nyocha ọnụọgụ nke potassium permanganate.

5 C2H2O4 + 2 KMnO4 + 3 H2SO4 →K2SO4 + 2 MNSO4 + 8H2O + 10 CO2;

Oxalic acid nwekwara ike ibelata ígwè trivalent ka ọ bụrụ ígwè bivalent. N'ihi nnukwu solubility nke ígwè bivalent na mmiri, anyị nwere ike itinye ụkpụrụ a iji wepụ nchara na uwe.

Oxalic acid nwere ike meghachi omume na phosphorus pentachloride iji mepụta phosphorus oxychloride. C2H2O4 + PCl5 → POCl3 + CO + CO2 + 2 HCL.

Oxalic acid nwere ike meghachi omume na ọtụtụ ọla iji mepụta nnu oxalic acid. Na mgbakwunye na nnu alkali metal na nnu bivalent iron salts na nnu oxalic acid ndị ọzọ na-esighị ike na mmiri. Ụfọdụ nnu ígwè, ọ bụ ezie na esichaghị ike na mmiri, nwere ike ịmepụta mgbagwoju anya nke na-agbaze na mmiri.

Fe2 (C2O4) 3 + 3 K2C2O4 + 6 H2O →2 K3 [Fe (C2O4) 3] • 6 H2O.

N'elu kpo oku, alkali metal na alkaline ụwa metal oxalic acid nnu nwere ike ida carbon monoxide na-etolite carbonates na carbonate na-aga n'ihu na-n'okpuru kpo oku ga-n'ihu decomposed n'ime oxide na carbon dioxide. Nnu oxalic acid nke nickel, cobalt na ọlaọcha nwere ike mechaa mepụta ọla kama ịbụ oxide na-abụghị metal.

Ngwaahịa na-emebi emebi nke oxalate bụ carbon dioxide, carbon monoxide na mmiri.

Oxalate na oxalic acid nnu na-egbu egbu. Oke, site na nchịkwa ọnụ, nwere LD50 nke 2000 ~ 4000 mg / kg.
