Best way to get rid of hypochlorite?
If I was to attemp a hoffman rearrangement of benzamide to aniline, there would be still some hypochlorite present if I used excess. I read that
aniline zinc chloride double salt is insoluble (I think in encyclopedia of purification of reagents or something like that) and is a good way to
purify aniline. So I would acidify the solution, but wouldn't want to form any chlorine.
What would be the best way to get rid of hypochlorite in solution?

H2O2 would probably work. It reacts with hypochlorite to form O2 and NaCl.
H2O2 typically does not oxidize amines very readily, although in some situations it can.

Haha no worries bfesser 
Anders, any other alternatives to H2O2? I have very old 3% solution only and I guess it's actually like 100% H2O by now.

Thiosulfates will reduce hypochlorite, but I am unsure whether or not they react with aniline.

I don't know bfesser, Beginnings or General Chem forum.. anything works for me. It's not like the thread is going to get lost somewhere
Justin, I have considered this yet it will still release SO2 on acidification. I think I read somewhere that sulfur reacts with hypochlorite so I
could just filter excess but I am not sure. Don't want to make any H2S.

thinking about removing oxygen from compounds one thing comes to mind...
CO + Fe2O3 > Fe + CO2
PLAUSIBLY this could work the same way with NaClO
ammonia is what i usually use to remove acidic vapours, but you might not want to open a bottle of ammonia anywhere near NaClO as trace amounts of
hydrazine can be formed along with alot of chloramines

The reaction of sodium hypochlorite with hydrogen peroxide goes via singlet oxygen. This is noticeable as the mixed solution is a much more powerful
oxidiser than the two reagents apart and under certain conditions chemiluminescence can be observed.
Singlet oxygen may well chew up your aniline.
