Beryllium oxalate is an inorganic compound, a salt of beryllium metal and oxalic acid with the chemical formula Шаблон:Chem.[1] It forms colorless crystals, dissolves in water, and also forms crystalline hydrates. The compound is used to prepare ultra-pure beryllium oxide[2] by thermal decomposition.[3]

Synthesis

The action of oxalic acid on beryllium hydroxide:[4]

<math>\mathsf{Be(OH)_2 + H_2C_2O_4 \ \xrightarrow{}\ BeC_2O_4 + 2H_2O }</math>

Chemical properties

Crystalline hydrates lose water when heated:

<math>\mathsf{BeC_2O_4\cdot 3H_2O \ \xrightarrow[-2H_2O]{100^oC}\ BeC_2O_4\cdot H_2O \ \xrightarrow[-H_2O]{220^oC}\ BeC_2O_4}</math>
