WebThe equatorial bonds in cyclohexane are those that lie in the plane and are shown going in the direction away from the equator. They are not at a right angle but more than that, so equatorial bonds are sightyly slanted.Their orientation is as per that of axial bond on the same carbon atom.. For upward axial bond, equatorial bond will be ... WebTherefore, the cleavage of the >C ar-O- bridge bond in ODB first undergoes partial and/or complete hydrogenation aromatic ring in ODB by the H‧‧‧H transfer. Interestingly, with the increasing Si/Al ratios, Ni 13% /HZ-5(200) has low cyclohexane yield in catalytic HDO due to the less acid sites, which causes poor hydrodeoxygenation activity.
