Diethyl Ether Explosive Peroxides

I ve never stored diethyl ether before but am thinking of producing minor amounts myself and storing said ether inside of glass ptfe bottles.

Diethyl ether explosive peroxides. Citation needed ether is sensitive to light and air tending to form explosive peroxides. Diethylene glycol dimethyl ether diglyme 4 methyl 2 pentanol. Then any movement of the apparatus could cause the dry and shock sensitive peroxides crystal to explode. Diethyl ether is highly volatile and has a low flash point and a low explosive limit by volume in air.

Diethyl ether hydroperoxide can be formed by. Auto oxidation reaction is observed with common ethers such as diethyl ether diisopropyl ether tetrahydrofuran and 1 4 dioxane an illustrative product is diethyl ether peroxide such compounds can result in a serious explosion when distilled. The diffusion of diethyl ether in air is 9 18 10 6 m 2 s 298 k 101 325 kpa. Di isopropyl ether seems to be unusually susceptible to this type of peroxidation.

Explosions can also occur when containers of peroxide containing liquids are merely jolted or the peroxides ignite as a result of friction upon opening. The extraction process concentrated the peroxides in the bottom of the round bottom flask and along the glass vessel of the apparatus. Ethylene glycol ether acetates glyme 1 phenylethanol. The reaction is accelerated by light metal catalysts and aldehydes.

Euh066 repeated exposure may cause skin dryness or cracking. Ether peroxides have a higher boiling point than ether and are contact explosives when dry. Diethyl ether will slowly form explosive peroxides in storage though addition of a small amount of butylated hydroxytoluene bht or storage over sodium hydroxide will prevent this. Explosive mixture or when disturbed by unusual heat shock or friction.

Form explosive peroxides when distilled evaporated or otherwise concentrated. When stored in the presence of air or oxygen ethers tend to form explosive peroxides such as diethyl ether hydroperoxide. Diethyl ether hydroperoxide is the organic compound with the formula c 2 h 5 och ooh ch 3 it is a colorless distillable liquid. Diethyl ether is best stored in narrow neck reagent glass bottles.

In addition to avoiding storage conditions likely to form peroxides it is recommended when an ether is used as a solvent not to. Pictogram signal word danger hazard statement s h224 extremely flammable liquid and vapour. Diethyl ether cas no 60 29 7 material safety data sheet sds msds. I am aware of possible pressure build up due to vapors and storage temperature but what always puts me off is the formation of explosive peroxides.

Care must be taken not to distill ether to dryness due to the trace amounts of peroxides formed. Diethyl ether ether 2 pentanol. Euh019 may form explosive peroxides.
