Thermal decomposition of lithium peroxoborate
- 18 Downloads
In the case of the decomposition of LiBO3·H2O under vacuum in the interval 115–145°, 50% of the oxygen is retained in the solid phase, while 50% is liberated in the form of O2. In this case 0.5 mole H2O is lost. The empirical composition of the substance formed is LiBO2.7·0.5H2O. Complete removal of H2O occurs at 250–300°. The activation energy of the decomposition of the peroxo-anion is 46 kcal/mole.
