Gas-agitated liquid and oxidative extraction in the alkyl anthraquinone process for the preparation of hydrogen peroxide
As preliminary investigations on oxidative extraction in the alkyl anthraquinone process for the production of hydrogen peroxide, the air-agitated liquid extraction of hydrogen peroxide from the working solution was studied and the dynamics of the extraction was measured as a function of the oil/water ratio and gas flow rate. The investigations were carried out either in an empty column or in a packed column. The results proved that the use of gas-agitated oxidative liquid extraction was a good way to integrate the oxidative operation unit with the extraction unit in the alkyl anthraquinone process for the preparation of hydrogen peroxide.
