Beryllium Phosphite 化学特性,用途語,生産方法
説明
Beryllium phosphite can have the formulas of either
Be(OH)HPO3 or Be(OH)(H2PO3)2. It is the former that
appears when phosphorous acid is reacted with the
oxide, hydroxide or carbonate:
BeO (s) +H3PO3 (aq) ? [Be(OH)]2HPO3
The product is the hydrogen phosphite. If the sodium
salt is employed, then the product is likely to be the
phosphite:
BeO (s) + Na3PO3 ? [Be(OH)]3PO3
On heating, it decomposes around 400°C to form the
pyrophosphite:
3[Be(OH)]3PO3 + heat ? Be3(PO3)2 = {Be3P2O6}
+ 3H2 + PH3
