Introduction

Oxalic acid is an organic acid with the systematic name ethanedioic acid and chemical formula

HO−C(=O)−C(=O)−OH, also written as (COOH)2 or (CO2H)2 or H2C2O4.

It is the simplest dicarboxylic acid. It is a white crystalline solid that forms a colorless solution in water.

Its name is derived from early investigators who isolated oxalic acid from flowering plants of the genus Oxalis,

commonly known as wood-sorrels. It occurs naturally in many foods.

Excessive ingestion of oxalic acid or prolonged skin contact can be dangerous.

Physicochemical property

Our manufacturing process

Oxalic acid is produced primarily by oxidizing carbohydrates or glucose with nitric acid or air in the presence of vanadium pentoxide.

Another method is to regenerate nitric acid using oxygen, using a variety of precursors, including glycolic acid and glycol.

 As of 2011, only the Japanese company Mitsubishi has used this process.

A newer method requires oxidative carbonylation of alcohols to obtain dioxalate:

4 ROH + 4 CO + O 2 → 2 (CO 2 R) 2 + 2 H 2 O
These diesters are then hydrolyzed to oxalic acid. About 120,000 tons are produced annually.

Historically, oxalic acid was prepared by applying a caustic base (such as sodium hydroxide or potassium hydroxide)

to sawdust and then acidifying the oxalate with an inorganic acid (such as sulfuric acid).

Oxalic acid can also be formed by heating sodium formate in the presence of an alkaline catalyst.

Application

The main uses of oxalic acid include cleaning or bleaching, especially for rust removal (iron complexing agent).

Its use in rust remover is due to the fact that it forms a stable water-soluble salt with trivalent iron, namely the iron oxalate ion.

Oxalic acid is an ingredient in some teeth whitening products. About 25% of oxalic acid is used as a mordant in the dyeing process.

It is also used in bleach, especially for pulping wood, cork, straw, rattan, feathers, as well as for rust removal

and other cleaning, for baking powder, and as a third reagent in silica analysis instruments.
