Summary
-
1.
Lithium peroxide diperhydrate Li2O2· 2H2O2 may be obtained by the action of concentrated hydrogen peroxide on lithium peroxide hydrate monoperhydrate Li2O2· H2O2· 2H2O at low temperatures.
-
2.
Li2O2· 2H2O2 preparations are stable only when they are completely free from mother liquor. The mother liquor may be removed from Li2O2 · 2H2O2 preparations in vacuum at low temperatures.
-
3.
The individuality of the compound Li2O2 · 2H2O2 was confirmed by differential thermal and qualitative x-ray phase analyses.
