2HBr + 2H202 --> 1Br2 + 2H20 + 2OH
Isn't it 2HBr + H2O2 --> Br2 + 2H2O?
Could the diiodoisosafrole bee made by using I2 instead?
Isn't it 2HBr + H2O2 --> Br2 + 2H2O?
Not that it matters very much in the end, but when you make bromine from NaBr+H2O2+HCl there will be no HBr at all in your reaction mix.
There would be HBr formed if you used H2SO4.
Well, there will be H+ and Br-, which is just as good
...for oxidising the Br- into Br2, yes. For making Hydrobromic acid, no.
Admitted: that was not the topic. It was just all these NaBr+HCl ---> NaCl+HBr-like equations above that triggered my corrective instincts.
O well, I'm off now mixing vinegar with gypsum, cause I'm almost out of sulfuric... ::)

(uemura: "Re: Ketones from Propenylbenzenes via the di-bromides", Novel Discourse). As far as developing the procedure using cl2, someone needs to balance out some equations. Maybe later.
