Benzene via K2Cr2O7
Is it possible to oxidize the alkyl substitutant with a dichromate ion to convert it into benzoic acid. I think I would add stoichiometric am mounts
with toluene in sex was and then reflux just like the permanganate method. Then combine the benzoic acid with NaOH and distill the benzene.
Has anyone ever used potassium dichromate instead of permanganate?

in some HCl to precipitate the Benzoic Acid. Then combine the benzoic acid with NaOH and distill the benzene.

No, but according to this, it works
http://pubs.rsc.org/en/content/articlelanding/1951/jr/jr9510...
and it is also produces benzaldehyde, and a few other compounds.
The KMnO4 method probably also produces a bunch of compounds, the majority being potassium benzoate.

LOL, I think we would all like stoichiometric amounts of sex!
In any case, it works (albeit with an ugly product distribution). The KMnO4 method is most often cited in the literature.

In my neighborhood we would just buy some Sodium Benzoate. Some people use it in canning. ( I think.)
Or, you could Chlorinate Toluene, then hydrolyse it.

He is probably a home chemist like most of us here. Experiment to us means experience. It also means fun, enjoyment, learning.
