Oxidation of o-xylene to phthalic acid/anhydride in liquid phase.
I was looking for a better way to produce moderate quantities of phthalic anhydride and I came across this article
<url>http://www.lookchem.com/Chempedia/Chemical-Technology/Organic-Chemical-Technology/7832.html</url>. It mentions in a short paragraph
oxidation of o-xylene to phthalic acid without the use of a V2O5-TiO2 catalyst in the liquid phase (something more laboratory friendly). The
catalysts should be relatively easy to get and yield is reported to be 90%, which is better than what I've heard of for vapor phase oxidation. My
question is what "Soluble acetates or naphthenates of Co, Mn, or Mo are generally used with cocatalysts containing bromine." means exactly, does it
mean [soluble acetates] or [naphthenates of Co, Mn, or Mo] or [soluble acetates or naphthenates] of [Co, Mn, or Mo].
