Specific features of dehydrogenation mechanism

Conjugated ethylbenzene dehydrogenation by 15% aqueous hydrogen peroxide. 

Oxidative ethylbenzene dehydrogenation by oxygen in an amount equivalent to its concentration in 15% aqueous hydrogen peroxide at complete dissociation of the latter. 

Ethylbenzene dehydrogenation in the simultaneous presence of hydrogen peroxide and molecular oxygen. 

Experimental results on conjugated ethylbenzene dehydrogenation with hydrogen peroxide, shown in Table 4.2 (experiments 1 and 2), indicate that the use of 15% aqueous hydrogen peroxide promotes high yields of styrene for both the missed and the converted ethylbenzene 36.3% and 90%, respectively1. 

for this reaction H202 is a highly active dehydrogenating agent.
