Rubidium peroxide

Production

Rubidium peroxide can be produced by rapidly oxidizing rubidium in liquid ammonia at −50°C.

${\displaystyle 2\mathrm{R}\mathrm{b}+{\mathrm{O}}_2\stackrel{-50{}^{\circ }\text{C}}{\to }\mathrm{R}{\mathrm{b}}_2{\mathrm{O}}_2}$

It can also be produced by pyrolysis of rubidium superoxide in vacuum.

${\displaystyle 2\mathrm{R}\mathrm{b}{\mathrm{O}}_2\stackrel{290{}^{\circ }\text{C}}{\to }\mathrm{R}{\mathrm{b}}_2{\mathrm{O}}_2+{\mathrm{O}}_2}$
