Yes probably, but I didn't think about the possibility of isomers until I tried to recrystallise the and found the acid melted at a rather low
temperature. By this time I had hydrolysed all that I had. I have thought about trying to use TLC or paper chromatography to charaterise the acids and
compare them with bought or acids prepared by unambiguous routes (I have p-toluic acid, o-toluidine and o-xylene so this shouldn't be too difficult).
An interesting observation I made while dissolving BaCO3 and m-toluic acid in water it required about 30% more carbonate that theory. I have no
explanation for this.

I have just posted in the prepublication section my write-up on my experiments into the hydrolysis of DEET if anyone wants to talk a look.
