potassium trihydrogen dioxalate(Cas 127-96-8) Usage
|
Preparation |
Potassium oxalate can be preparaed by heating potassium formate at 360°C:2HCOOK →K2C2O4+ H2The salt is obtained as its monohydrate by neutralization of oxalic acid with a dilute aqueous solution of potassium hydroxide followed by crystallization:H2C2O4+ 2KOH →K2C2O4+ 2H2O. |
|
Flammability and Explosibility |
Nonflammable |
|
Purification Methods |
Crystallise it from water below 50o. Dry it below 60o at 760mm. [See potassium oxalate above, Beilstein 2 IV 1823.] |
|
Physical properties |
The monohydrate is a white crystalline solid; monoclinic structure; density 2.13 g/cm3; loses its water at about 160°C; converts to carbonate when ignited; effloresces in warm dry air; soluble in water, 33 g/100 mL at 20°C; a 0.05m solution of K2C2O4?2H2O has a pH 1.679. |
