Ortho xylene oxidation
Xylene xylol or dimethylbenzene is any one of three isomers of dimethylbenzene,
or a … The isomers can be distinguished by the designations ortho- (o-), meta- (m
-) and para- (p-), which specify to which … Of the three isomers, the p-isomer is
the most industrially sought after since it can be oxidized to terephthalic acid.15 May 2011 … The oxidation of o-xylene (OX) to phthalic anhydride (PA) is one of the important
