CAS No.: 144-62-7 Chinese Name: Oxalic acid English Name: Oxalic acid; Ethanedioic acid; Dicarboxylic acid Alias: Ethanedioic acid; Acid of sorrel Content: 99.6% Molecular Formula: H?C?O? Molecular Weight: 90.04 EINECS No.: 205-634-3 Package: 25KG/bag Specification: National Standard Usage: Used in the chemical industry to produce pentaerythritol, cobalt oxalate, nickel oxalate, basic green, steel and soil analysis reagent kits, chemical reagents, etc. Acts as a color-developing and dyeing aid in rapid dyeing processes. Serves as a bleaching agent for straw and wheat straw products (oxalic acid has reducing properties) and as a rust stain remover (oxalic acid reacts with iron to form soluble iron oxalate, which is easily washed away, thus removing iron stains from fabrics). Physical Properties: Oxalic acid is an anhydrous, transparent crystal or powder with a sour taste. It is highly soluble in ethanol, soluble in water, slightly soluble in ether, and insoluble in benzene. Storage and Transportation: Store and transport oxalic acid at temperatures not exceeding 40°C. Protect from moisture and rain. Keep separate from alkaline substances and avoid contact with food. During handling, prevent direct skin contact.
