      Column length for MM Hg/Al  Bookmark   

SWIM wants to do the MM Hg/Al reaction in a 2Litre, 2 neck flat bottom flask. Is a 200mm condenser enough to contain the reflux? Would it be better to stack the condenser on top of a vigreux column? How are the smells for this reaction? THanks Peace

Anytime that you are unsure and have the available materials/glassware, it is a good idea to add another bit of length.  Put a short or medium length vigreaux on there and then the condensor, it won't hurt*, but it may help.

  This gives additional notes on the factors can influence the reaction.  So, yes it may be affected, but it shouldn't be by much.

Act quickly or not at all.

      Or if containing a runaway reaction is the concern  Bookmark   

Or if containing a runaway reaction is the concern you could add a length of clear vinyl tubing or other such tubing to contain the possible Al/Hg Volcano.
