Oxalic acid (99.6%, 99.4%,99%)

Oxalic acid forms fine colourless crystals, readily soluble in water, with light nitrogen oxides-like odour.

Oxalic acid forms fine colourless crystals, readily soluble in water, with light nitrogen oxides-like odour.Oxalic acid dihydrate begins to dissociate at temperature over 30°C.If heated quickly, it melts at 101.5°C,anhydrous oxalic metals at 180°C.

Oxalic acid used for purifying agent in pharmaceutical industry,special in antibiotic medication, 

such as oxytetracycline, chloramphenicol,etc;Precipitating agent in Rare-earth mineral processing; 

Bleaching agent in the textile activities,wood pulp bleaching;Rust-remover for metal treatment;

Grinding agent,such as marble polishing;Waste water treatment,removing calcium from water.

25kg /50kgPP bag of top grade linerfilm,good properties of waterproof and avoid water,solarization.
