Conjugated Dehydrogenation with Hydrogen Peroxide

The induration zone should be as close to the reaction zone as possible. Such an induration system is applied to prevent oxidation of the reaction products outside the reaction zone.

These studies determined the range of parameters of cyclopentane conjugated dehydrogenation with hydrogen peroxide [75],... 

The reaction of piperidine conjugated dehydrogenation with hydrogen peroxide [99] opens the way to dehydrogenation of natural compounds, which include piperidine fragments. As shown by experimental data, pyridine yield increases from 45% to 65.2% with hydrogen peroxide concentration from 20% to 25%, respectively, with reaction selectivity above 98%. A further increase of H202 concentration reduces pyridine yield to 59%. It follows from these... 

In this regard, the above-suggested mechanism of ethylbenzene conjugated dehydrogenation with hydrogen peroxide presents a satisfactory explanation of styrene formation. Here the central place belongs to a new elementary reaction ... 

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. 

The above discussed were several aspects of ethylbenzene conjugated oxidation (dehydrogenation) with hydrogen peroxide. This reaction was studied in detail in many investigations... 

The efficiency of conjugated dehydrogenation of olefins with hydrogen peroxide was also confirmed in studies of propylene dehydrogenation to allene [60], The well-known process of propylene oxidative dehydrogenation to allene in the presence of iodine [61] at 625-700 °C gives low yields of the target product (3.6% allene) at low selectivity of the process (6%).
