Abstract: PROCESS FOR MANUFACTURING A PURIFIED AQUEOUS HYDROGEN PEROXIDE SOLUTION Process for manufacturing a purified aqueous hydrogen peroxide solution, in which a crude aqueous hydrogen peroxide solution is subjected to a washing operation with at least one organic solvent, and wherein an organophosphorus chelating agent is added to the organic solvent.
1. A process for manufacturing propylene oxide (1,2-epoxypropane) by reaction of
propylene with hydrogen peroxide, said process using a hydrogen peroxide solution
containing less than 100 ppb of Al and/or Fe which is a crude aqueous hydrogen
peroxide solution which has been obtained by an AO (auto-oxidation) process.
2. The process as claimed in claim 1, wherein the hydrogen peroxide solution contains Al and/or Fe in the range of 10 ppb.
3. The process as claimed in claim 1, wherein the hydrogen peroxide solution contains below 1 ppb of Al and/or Fe.
4. The process as claimed in claim 1, wherein the hydrogen peroxide solution contains less than 100 ppb of Cr.
5. The process as claimed in claim 4, wherein the hydrogen peroxide solution contains Cr in the range of 10 ppb.
6. The process as claimed in claim 4, wherein the hydrogen peroxide solution contains below 1 ppb of Cr.
