Maybee somebee has a use for this.
I found this somewhere.
This guy has some funny comments "Don't put this in someones eyes, Hehehe
Bromacetone
Bromacetone is a strong lacrimator or tear gas, in stronger concentrations it is also a nerve gas. This chemical is not very difficult to synthesize. In its purest form one only needs acetone, water and bromine. A very small amount of strong acid is also needed, we can use concentrated sulphuric acid.
First we mix water and acetone in equal amounts. Then the sulphuric acid is added and mixed Afterwards we add a little bromine and mix. After the brown color of the reaction`s vessel is gone, we add more bromine. And so on. Soon we can see a second layer in the reaction vessel, on the bottom is the heaviser bromacetone.
CH3COCH3 + H2O + H2SO4 +Br2 => CH3COCH2Br
Now we can stop the reaction. We have synthesized some bromacetone, and we don`t need much. There is no reason for making more bromacetone than we can use at once, because it is not very stable. After a time it decomposes and becomes black.
Bromine is a dangerous chemical, and it is difficult to bay. Bromine on the skin gives terrible wounds. So it is better to synthesize bromacetone without bromine. Thus we can use potassium bromide and a very strong hydrogen superoxide instead of bromine.
We mix acetone and water and some sulphuric acid as before. Then we ad some potassium bromide and mix well till we get a clear solution. Then we add some superoxide and the solution becomes brown. After the brown color has vanished, we add more hydrogen superoxide. When a small amount of bromacetone has made a second layer on the bottom of the reaction vessel, we can stop the reaction.
CH3COCH3 + H2O + H2SO4 + KBr + H2O2 => CH3COCH2Br
Warning: Never put bromacetone directly in someone`s eyes!
