Acetone and Hypochlorite


Does anyone know how adding Acetone decomposes the excess hypochlorite after a treatment of sodium hypochlorite solution?

Do an internet search on the "haloform" reaction. Chloroform is formed at high pH. At much lower pH, chloroacetone (causes strong tear production in the eyes) is formed.

I see if you do a Haloform reaction, (using sodium hypochlorite as the source of both base and chlorine?) you get a carboxyllic acid and CCl3-, or RCOO- and chloroform, but then when you add acetone, after the chloroform is expelled, how does the acetone destroy the exess hypochlorite?

Oh, the acetone and the NaOCl go through another Haloform reaction?

So you get propanoic acid and chloroform again? Where did the -OH come from to make the acid?

How about DETRITUS?

There's an entire forum library for answers to basic questios like the mechanism of the haloform reaction.

Read Gattermann, read Vogel, read Cohen.
