Why Stored Ethers Can Form Explosive Peroxides

Stored ethers can slowly turn dangerous because they react with oxygen in air and form peroxides. This process is called autoxidation, which means a compound oxidizes on its own while standing in air. Over time, ethers can produce hydroperoxides and dialkyl peroxides.

These peroxide products can ...

When working with low molecular weight ethers, such as diethyl ether, two hazards must be avoided in the laboratory.

Firstly, given their low boiling points, ethers are highly flammable. Thus, care must be taken to keep them away from open flames or sources of electric sparks to prevent possible explosions, and they should be used inside...
