      Storage of Ethyl Bromide?  Bookmark   

  Besides the usual "should be stored in a cool, dry, well-ventilated area in tightly sealed containers", is there anything else I should know about storage of this chem? Is there something I could add to home-made ethyl bromide to preserve it for a few months?

it should be stored in very tightly sealed containers!
i had evaporate 20 ml into the lab atmosphere over some months shocked.
if you used drones method, you should shake it with 1/5th volume
of conc. H2SO4 to remove possible ether and then wash with
sodium (bi)carbonate and water.

it should be realtively stable, distill before use.

Alkyl halogenides are often stored over a piece of silver foil. Dunno why though.

      Silver in alkyl halides  Bookmark   

I'm not exactly sure of the mechanism, however storing alkyl halides with a small amount of silver wire or copper shot prevents discoloration and decomposition of the organics.  For example, I have seen numerous bottles of alkyl iodides from Aldrich, the most recent reagents were all shipped with a few copper beads(shot) rolling around in the bottom of the bottle.  The copper has completely prevented any discoloration from forming over a 5 year period.

I have a 25L flask from the 1950's still nice and clear. It's just standing in a basment.
