Anhydrous Oxalic Acid
Anhydrous acid is a king of tasteless hite powder sublimating in 110 ~ 120 ℃. In the dry heat air it can be weathered. 1g product can be dissolved in 7 ml cold water, 2 ml boiling water, 2.5 ml cold ethanol, 1.8 ml boiling alcohol, 100 ml ether, 5.5 ml glycerol but benzene, chloroform and petroleum ether. 0.1mol / L liquor had 1.3pH. The relative density is 1.653 and melting point is 189.2 ℃ -189.5℃
Anhydrous acid 99.5% for lithium battery-grade low iron ions
