The method I use is cheaper, (doesn't require H2SO4).
HCl+NaBr, then redox with Ca(ClO)2.
First picture: my three different attempts, the same quantity of reactants was used each time, I can proudly say my yield improved greatly!
Other pics: my most recent attempt (did that today actually)
I do have to say be careful with this reaction, your method seems to give a calmer reaction, on my first attempt the Ca(ClO)2 reacted so furiously it
gave a coke + mentos fountain - except with a vile mixture of acids and Bromine gas. I ran - hence the tiny yield, just thought I'd share my story.
Also anyone know how to safely dispose of the by product? I'm thinking dilute the f* out of it and flush it down the toilet, but I'm not sure that's
what one is supposed to do... For now the stuff is sitting in glass jars.
Still congrats on the Bromine isolation! It is a pretty rewarding reaction.
As for storage, ampules work fine, I haven't found a need to refrigerate it, last thing I want is for someone to eat an unusually flavored
Popsicle.
