Process for the on-site production of ultra-pure hydrogen peroxide for the electronics industry, involves the use of an organometallic complex of cobalt and the reduction of oxygen in an acidic medium |
摘要 |
The hydrogen peroxide is obtained by the oxidation of a cobalt (II) complex in an acidic medium, the organic ligand being a polyazabicylo(6,6,6)eicosane and the installation being on-site and coupled with an additional purification unit if necessary. The process comprises the stages : (a) reduction of dioxygen in an acid medium with an organometallic complex on an inert support which is capable of being oxidized; and (b) separation of the oxidized complex obtained from the formed hydrogen peroxide by solid/liquid extraction; An Independent claim is also included for the installation by which the process is carried out.
