With what "common" reagent would butane react if pumped into them (except HNO3, as I know which would form a nitro-derivate)?
Ex. aq. CH2O, aq. NH3, conc. HCl.....

Any information/experience wellcomed!

70mL of chlorine and 140mL of butane were introduced into a coke bottle and left in the sun for 24h. After 24h the ph of the water below the gasses was around 1, and the liquid had a slightly thicker than usuall meniscus, and smelled organic. I attempted to separate into two layers using a burette, but two layers did not form. So a reaction definatly did occur, but strangly two layers did not form.

It was clear that this would happen.
Chlorobutane definately formed, and also condensed, but the formed amount is way too small.
Calculate the expected yield of chlorobutane and see why you got nothing.

You need to react many liters each of butane and chlorine!

Actually, I just made a stupid mistake in calculating how much chlorobutane would be formed, in using pv=nRt to get my moles of gas I forgot to convert temperature to Kelvin so I was getting a theoretical yield of 2.6g instead of 0.3g. oops

Here are just a little of the UNDEFINED uses for butyl chloride:
-preparation of butyl sulphide and other smelling compounds
-solvent for much things
-synthesis of metallic-organic compounds, like butyl aluminum (great pyrophoric substance)
and much others.......

Because of the small ratio of butyl chloride from Cl2 and C4H10 I'm searching a flask or something bigger than a 2 liters bottle to make react the 2 gases.....

Does anyone know what butane reacts with, other than chlorine and bromine?
