Thanks for the links! This seems to be by far the easiest method of preventing peroxide formation.

Do you want to say that copper catalyzes the decomposition of organic peroxides into oxygen and the original organic compound?


Not exactly but close. I think the reason why it's not widely known is because it was a patented monopoly. The patent says "If the ether contains peroxides, the action of copper results in the formation of a small amount of organic acids" and magnesium hydroxide is recommended for removing these to apparently give pure ether. Much ether was packaged under this patent by Squibb. Alumina is a one step substitute nowadays.
