Hydrogen peroxide integrated process

Therefore, this sensor integrates a biochemical and a chemical reaction with a prior separation (dialysis) and chemiluminescence detection. The process involves the following steps (a) dialysis of the enzyme (6) enzymatic oxidation of the reagent (c) derivatization of hydrogen peroxide and d) detection of the chemiluminescence produced. Such an original approach offers several advantages over similar methodologies, namely ... 

The reaction of methane oxidation with hydrogen peroxide under pressure was studied on an automated micropilot flow unit with integral reactor based on the standard double reactor OL 105/02 system. The OL 105/02 system is usually used in studies of pressurized homogeneous and heterogeneous processes in gas and liquid [123]. The micropilot unit has two equal reactors of 250 cm3 volume and is equipped with standard metering, recording and control instruments. 

Arco have developed an integrated process for the production of industrially important epoxides via an adapted AO process (Figure 1.13).33 34 A sulfonic acid substituted alkylhydroanthraquinone alkylammonium salt is reacted with molecular oxygen to form the alkylanthraquinone and hydrogen peroxide. The hydrogen peroxide is then reacted with an alkene in the presence of a titanium zeolite catalyst (TS-1 see Chapter 4). The epoxide product is then separated, and the anthraquinone salt recycled to a hydrogenator for reaction with... 

A number of electrochemical processes have been employed in an integrated approach for the production of hydrogen peroxide which is subsequently used to oxidize organic functional groups. The electrochemical processes have not only been employed for the preparation of fine chemical intermediates,39 but also for the destruction of organic pollutants in water courses.40... 

The integration of propene oxide and hydrogen peroxide processes appears, from a short-term perspective, a more realistic approach than in situ generation. It is also favored by the location of both facilities at the same chemical site. Basically, process integration envisages a simplification of H2O2 recovery that can even... 

In principle, process integration applies even more to direct synthesis of hydrogen peroxide, further improving the advantages over the anthraquinone route. Methanol can be used to replace water as the solvent and the dilute methanol solution obtained fed into the epoxidation reactor. Minimal purification may be required, for example for the removal of hydrogen bromide and other additives that may have been needed to increase the selectivity. 

The relatively small capacity of the phenol hydroxylation process does not justify the development of alternatives to the use of commercial hydrogen peroxide. The direct synthesis of phenol, for which process integration might be crucial, would be a different matter.
