しゅう酸/カリウム,(2:1) 化学特性,用途語,生産方法
化学的特性
colorless or white crystal(s) [MER06]
物理的性質
The monohydrate is a white crystalline solid; monoclinic structure; density 2.13 g/cm
3; 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 K2C
2O
4?2H
2O has a pH 1.679.
天然物の起源
Potassium oxalate, along with calcium oxalate, is found in leaves and roots of certain plants. It is used for cleaning and bleaching straw and for removing stains. It also is used in photography, in clinical tests, as a secondary pH standard, and in wet chemical analysis. The analytical application involves standardization of many oxidizing agents in titrimetric analysis.
製造方法
Potassium oxalate can be preparaed by heating potassium formate at 360°C:
2HCOOK →K2C
2O
4+ H
2The salt is obtained as its monohydrate by neutralization of oxalic acid with a dilute aqueous solution of potassium hydroxide followed by crystallization:

純化方法
Crystallise it from water below 50o. Dry it below 60o at 760mm. [See potassium oxalate above, Beilstein 2 IV 1823.]
