Abstract
Process for preparing hydrogen peroxide, comprising the following steps: a) a step of reduction of dioxygen in acidic medium with a hydrophobic organometallic complex, and b) a step of separation of the oxidized organometallic complex resulting from step a) and of the hydrogen peroxide by liquid/liquid extraction.
Claims11
A process for preparing hydrogen peroxide, comprising:
- a) reducing dioxygen in an acidic medium with a hydrophobic organometallic complex, thereby forming hydrogen peroxide and an oxidized organometallic complex;
- and
- b) separating the oxidized organometallic complex resulting from step a) from the hydrogen peroxide by liquid/liquid extraction.
