hello
i am wondering if you could remove one carboxyl group from terephthalic acid to make benzoic acid. what would be the condition this rxn would take
place in? if this rxn took place at reasonable temps, pressures,etc, then this would be my source of the benzene ring.

I think it would be very hard if at all possible to selectivly decarboxylate the phthalic acid and even if you could the rxn would probally go on to
decarboxylate the benzoic acid forming benzene.

I would have to agree with Brominator. Also, terephthalic acid is a lot more expensive and less widely available than benzoic acid . . . unless you
are just doing it on a small scale to prove a point, I would just buy some of the latter off eBay very cheaply as a food preservative or something.

i can get lots of terephthalic acid from breaking down pet bottles.
i have no source of benzoic acid
is there any way to turn it into salicylic acid, phenol, benzene etc? i just need something more commonly used than this chem
