Conjugated Oxidation with Hydrogen Peroxide

As mentioned above, at gas-phase conjugated oxidation with hydrogen peroxide in a flow system with stationary mode H02 radical concentration is several orders of magnitude higher than "OH radical concentration. Based on this fact and literary data on olefm epoxidation... 

Figure 4.21 Temperature dependencies of selectivity (y) (1), yields (/ ) of propylene oxide (2), acrolein (3) and side products (4), and propylene consumption (a) (5) for conjugated oxidation with hydrogen peroxide, (a) 30% H202 vH q = 1.3ml/h vc jj = 150ml/h and (b) 10% H202 vh2Q2 = 3-78ml/h vc3H6 = 900ml/h- 2 2 3 6...

This example shows the extent to which conjugated reaction study is simplified, if scientists have data on general regularities of conjugated oxidation with hydrogen peroxide. 

Conjugated Reactions of Oxidation with Hydrogen Peroxide in the Gas Phase... 

From these positions, let us discuss conjugated reactions of substrate oxidation with hydrogen peroxide, which may be presented by the following generalized scheme ... 

Finally, the above investigations show that conjugated 4-EP oxidation with hydrogen peroxide with respect to reaction conditions may be targeted both to 4-VP and 4-VP N-oxide synthesis. 

The gas-phase propylene oxidation with hydrogen peroxide according to the conjugated mechanism is one of the major ways of synthesizing such valuable products as propylene oxide, acrolein and allene [124, 141,142],...
