Rustyshackleford is that a Friedel craft rxn U r talking about with phenol& benzoic acid and if so
Is benzophenone the resulting product?
Also does anyone think that anhydrous hbr& HI gas could be made from a room temperature
Mixing of polyphos acid and alkali halides?

The minor product of that reaction is 4 hydroxy benzophenone (16%) and major product is the ester (68%). I figure i can extract the organic layer and run a ketone test on it to see if the polyphosphoric acid i made works.
I attached the PDF the reaction is mentioned in (page 5)

As for the HI and HBr, i doubt it at room temperature but probably worth a try.

I never even considered the ester, obvious now it has been pointed out.
