Oxalic acid tau dav faib hauv cov nroj tsuag hauv qhov xwm, feem ntau nyob rau hauv daim ntawv ntawm oxalic acid ntsev. CW ScheeLe muaj thawj zaug tau tsim oxalate hauv 1776.

Oxalate yog cov acid muaj zog tshaj plaws ntawm cov dicarboxylic acid. Dhau li muaj cov khoom dav dav ntawm cov carboxylic acid, nws tseem muaj cov khoom txo thiab nce tuaj yeem txo xya lub peev xwm ntawm manganese. Cov cuab yeej no feem ntau siv rau kev ntsuas kom muaj nuj tshuaj ntawm poov tshuaj permanganate.

5 c2h2o4 + 2 kmno4 + 3 h2o4 → k2o4 + 2 mins4 + 8h2o + 10 CE2;

Oxalic acid kuj tseem tuaj yeem txo cov neeg sib tw ua ke mus rau hauv cov hlau balively. Vim hais tias yog cov solubility siab ntawm cov hlau balalent hauv dej, peb tuaj yeem siv lub ntsiab cai no kom tshem tawm xeb ntawm cov khaub ncaws.

Oxalic acid tuaj yeem hnov ​​mob nrog phosphorus pentachhloride los ua kom cov pa phosphorus oxychloride. C2h2o4 + PCL5 → POCL3 + CO + CO2 + 2 HCL.

Oxalic acid tuaj yeem ua rau muaj ntau hlau los ua cov tshuaj pleev oxalic acid ntsev. Ntxiv nrog rau cov alkali hlau ntsev thiab cov khoom siv hlau tsis zoo nrog cov kua Oxalic acid ntsev tau zoo soluble hauv dej. Qee cov ntsev me, txawm hais tias tsis zoo soluble hauv dej, tuaj yeem tsim cov nyom uas yog soluble hauv dej.

FE2 (C2O4) 3 + 3 K2C2O4 + 6 H2O → 2 K3 [Fe 2 (C2O4) • 6 h2o.

Thaum cov cua kub, alkali hlau thiab alkaline ntiaj teb hlau oxalic acid ntsev tuaj yeem raug decomposed rau oxide thiab carbon dioxide. Cov tshuaj pleev oxalic acid ntsev ntawm Nickel, cobalt thiab nyiaj tuaj yeem thaum kawg tsim cov hlau hloov ntawm cov oxium tsis.

Cov khoom siv decomposing ntawm oxalate yog carbon dioxide, carbon monoxide thiab dej.

Oxalate thiab oxalic acid ntsev yog tshuaj lom. Cov nas, los ntawm kev tswj hwm qhov ncauj, muaj LD50 ntawm 2000 ~ 4000 mg / kg.
