Column length for MM Hg/Al

[nitrous351]

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.

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.
