bubble bromine gas

[outdoor-man]

could you tell me how to bubble bromine gas into the rection solution with liquid bromine or something else. during the course, what should i be aware of?

[Mr Skeptic]

Is this homework help? Why is it in organic chemistry? Bromine is inorganic, although it is quite frequently used in organic chemistry. Also, bromine is toxic and not fun to breathe.

thanks for your reply and tips. it is not homework.i just want to know the way to synthesize a series of compounds. it was my first post.

Well, I think you'd have more luck with liquid bromine than gas, since it should be easier to dissolve and less likely to escape. I'd do the reaction outside (with a fan if it's not breezy).

You'd be better off with a solution of bromine in a pressure equalizing dropping funnel. Appropriate solvents would be glacial acetic acid, chloroform, or dichloromethane, depending on the reaction solvent. You can always add it straight in under strong stirring, but you'll need better control over the flow rate than for solutions.

You should be aware of the fact that bromine gas will kill you.
