Obtaining anthranilic acid from methyl red
I have a great amount of methyl red which I find useless for indicator purposes only, so recently I cleaved the Diazo bond with zinc in 50% sulphuric
acid, zinc granules are used as I don't have powder. The reaction took 2 days to go to completion. During the time, the very deep red solution
gradually fades to colorless, and now a clear solution is obtained
Now the problem came: How can I separate the two products and isolate them?? I suppose the only products are anthranilic acid and
N,N-Dimethyl-p-aminoaniline right? But as I neutralize the acid I don't get any precipitate (which the aniline should be insoluble) What's wrong with
my strategy /reaction??
