Miniaturization might also be used in the distributed production of chemicals. Two examples include the safe production of hydrogen peroxide from hydrogen and oxygen or the production of chemicals or fuels from synthesis gas. More detailed study into the potential improvements in product yields, waste minimization, and costs are required to fully understand the impact of miniaturization. At this time it offers the potential to produce hazardous materials or conduct potentially dangerous oxidation reactions on a small scale that is inherently safer. 

The direct route to hydrogen peroxide from hydrogen and oxygen is described in Chapter 5.4.1 (page 238). 

The high frequency oscillatory current during the silent electrical discharge in an ozonizer affects the chemical reaction in some way. A parallel relation exists between the high frequency current and the yield of hydrogen peroxide from hydrogen and oxygen, but not between the low frequency base current and the yield. 

New routes to hydrogen peroxide new methods for direct synthesis of hydrogen peroxide (from hydrogen and oxygen) in a controlled, safe manner could provide a lower cost oxidant that reduces the use of chlorine. For example, in situ generation of hydrogen peroxide can be used to produce propylene oxide in place of the chlorohydrin route and...

The direct synthesis of hydrogen peroxide from hydrogen and oxygen (Reaction 15.6) is in principle the simplest method by which to form hydrogen peroxide and is forecast to offer lower production costs and also require quite low levels of investment. 

Development up to the pilot scale (5 1/h) of the direct synthesis of hydrogen peroxide from hydrogen and oxygen in methanol, carried out in very safe conditions, has been reported in patent applications" " " and presented at international congresses. ...
