Abstract

A process for producing hydrogen peroxide from hydrogen and oxygen in the presence of a noble metal and a cationic polymer comprising a halogen-containing anion is disclosed. The cationic polymer improves hydrogen peroxide yield, and it can be easily recycled.

Claims (18)

1. A process for producing hydrogen peroxide, which comprises reacting hydrogen and oxygen in a solvent in the presence of a noble metal and a cationic polymer comprising a halogen-containing anion, wherein the noble metal is not encapsulated by the polymer.

2. The process of claim 1 wherein the cationic polymer comprises a functionality selected from the group consisting of ammonium, phosphonium, sulfonium, and mixtures thereof.

3. The process of claim 2 wherein the cationic polymer comprises ammonium ions.

4. The process of claim 3 wherein the cationic polymer comprises N-alkyl pyridinium ions.

5. The process of claim 1 wherein the halogen is selected from the group consisting of chlorine, bromine, and iodine, and mixtures thereof.

6. The process of claim 1 wherein the anion is inorganic.

7. The process of claim 1 wherein the anion is selected from the group consisting of chloride, chlorate, perchlorate, bromide, bromate, iodide, periodate, and mixtures thereof.

8. The process of claim 1 wherein the anion is bromide.

9. The process of claim 1 wherein the cationic polymer is prepared by reacting an alkyl halide with a vinylpyridine polymer.

10. The process of claim 9 wherein the alkyl halide is an alkyl bromide.

11. The process of claim 1 wherein the number average molecular weight of the cationic polymer is at least 5000.

12. The process of claim 1 wherein the cationic polymer is crosslinked.

13. The process of claim 1 wherein the noble metal is selected from the group consisting of rhenium, palladium, platinum, silver, gold, and mixtures thereof.

14. The process of claim 1 wherein the noble metal is palladium.

15. The process of claim 1 wherein the noble metal is elemental.

16. The process of claim 1 wherein the noble metal is supported on a carrier.

17. The process of claim 1 wherein the solvent is selected from the group consisting of alcohols, ethers, esters, ketones, carbon dioxide, water, and mixtures thereof.

18. The process of claim 1 wherein the reaction is performed in the presence of an acid.
