Nature:
Colorless crystalline, often contain two molecules crystal water heated to 100 degrees crystal water lost, as water oxalic acid.
No smell, taste is sour.
Uses:
Oxalic acid is mainly used for production and bleach, reducing antibiotic and borneolect drugs and refining rare metal solvent, dyestuff, tanning agent for reducing metal surface cleaning and processing, ree extraction, textile printing &dyeing and leather processing, catalyst preparation. Oxalic acid can be used to rust.
And the formation ofacid type oxalic acid salt solubility.
In addition, still can be used for synthesis of oxalic acid ester of oxalic acid, salt and other products, and grass in dimethyl oxalate ethyl ester and sodium oxalate, calcium oxalate maximum yield.
Packing: PP woven bag lined with plastic bag.
