Conclusions
-
1.
The decomposition of Li2O2·H2O2·2H2O to lithium peroxide at 50 and 75°C proceeds with intermediate formation of the compounds Li2O2·H2O2·H2O and Li2O2·H2O2.
-
2.
Optimum conditions for the synthesis of Li2O2·H2O2 were found.
-
3.
It was shown by the PMR method that the compound Li2O2·H2O2 (or lithium hydroperoxide, LiOOH) has a lithium peroxide monoperoxyhydrate structure.
-
4.
Compounds with the composition Li2O2·H2O2·2H2O and Li2O2·2H2O2 also should be considered as products of crystallization addition of H2O2 and H2O to Li2O2.
