Oxalic acid is a dicarboxylic acid found naturally in many plants, but industrial oxalic acid is supplied as a synthetic fine white powder. It is one of the most cost-effective reducing bleaches and rust-removal chemicals available to manufacturers and maintenance teams.
Supreme Petro Chemicals supplies oxalic acid powder from Chennai for textile, metal cleaning, leather, wood, stone, and industrial maintenance applications across South India.
What Is Oxalic Acid?
Oxalic acid has CAS number 144-62-7 and molecular formula C2H2O4. It is a white crystalline powder supplied as anhydrous oxalic acid or oxalic acid dihydrate, depending on source and specification.
It works as a strong reducing agent and chelating agent. This makes it useful for removing iron stains, rust, scale, and colour bodies in selected bleaching applications.
Industrial Applications
- Rust and scale removal: Oxalic acid reacts with iron oxide to form soluble iron oxalate. This makes it useful for metal cleaning without heavy mechanical abrasion. It is used in boiler descaling, radiator cleaning, and maintenance cleaning.
- Textiles: Used for bleaching natural fibres such as straw and cane, and in jute and wool processing where reducing action is required.
- Wood: Used as a wood brightener and stain remover. It helps remove tannin stains and iron stains from decking and timber surfaces.
- Leather: Used as a chrome tanning assistant and as a mordant in natural dyeing processes.
- Marble and stone: Used in polishing compounds for selected stone surfaces.
- Pharmaceuticals: Used as a synthesis intermediate. It is not supplied or used as an API in this context.
Safety
Oxalic acid is toxic if ingested and can irritate skin and eyes. It is corrosive to mucous membranes and can affect the kidneys at high exposures. Workers should use gloves, eye protection, and dust-control practices during handling.
Store bags in a dry, ventilated area away from incompatible materials. Follow the SDS for first-aid, spill handling, and disposal instructions.
