The catalytic hydrogenation and hydrogenolysis of isomeric dimethoxybenzenes over six platinum metals have been investigated at elevated temperature and pressure. The hydrogenolysis of methoxyl group occurred more extensively over Group VIII<SUB>3</SUB> metals than over Group VIII<SUB>2</SUB>metals. The <I>meta</I> isomer hydrogenolyzed to greater extent and gave smaller <I>cis/trans</I> ratio of dimethoxycyclohexane, than the <I>ortho</I> and <I>para</I> isomers. The greater tendency of the <I>meta</I> isomer toward hydrogenolysis supports the previously proposed explanation according to which the electron-releasing group at <I>meta</I> position would promote hydrogenolysis.
