LiOH - H2O2 - H2O trinary system study for the selection of optimal conditions of lithium peroxide synthesis

Using solubility method the decay kinetics of peroxide products contained in liquid phase of LiOH - H2O2 - H2O trinary system with 2 to 6% by wt hydrogen peroxide content in liquid phase in 21 to 33 degrees C temperature range has been studied. Conducted studies have allowed to determine temperature and concentration limits of solid phase existence of Li2O2 center dot H2O content, distinctness of which has been confirmed using chemical and qualitative Xray phase analysis. Stabilizing effect of solid phase of Li2O2 center dot H2O content on hydrogen peroxide decay contained in liquid phase of LiOH - H2O2 - H2O trinary system under conditions of experiments conducted has been shown.
