Abstract
Hydrogen peroxide is produced in a reaction between carbon monoxide, oxygen, and water in the substantial absence of gaseous hydrogen in the presence of a solvent using a soluble palladium compound as a catalyst and employing an arsine or phosphine ligand.
Claims31
A process for producing hydrogen peroxide by reacting carbon monoxide, oxygen, and water in the presence of a palladium catalyst wherein the improvement comprises carrying out said reaction in the presence of a soluble compound of Pd, an arsine ligand, a non-coordinating acid, water, and a solvent for said Pd compound and said ligand, wherein the molar ratio of CO/O.sub.2 is in the range of 1/100 to 50/100 and the molar ratio of said arsine ligand/Pd is at least 10/1.
A process for producing hydrogen peroxide by reacting carbon monoxide, oxygen, and water in the presence of a palladium catalyst wherein the improvement comprises carrying out said reaction in the presence of a soluble compound of Pd, at least one phosphine ligand selected from the group consisting of tris (p trifluoro methyl phenyl) phosphine and penta fluoro phenyl diphenyl phosphines, a non-coordinating acid, water, and a solvent for said Pd compound and said ligand, wherein the molar ratio of CO/O.sub.2 is in the range of 1/100 to 50/100 and the molar ratio of said phosphine ligand/Pd is at least 10/1.
The process of claim 28 wherein the temperature is in the range of -20.degree. to +50.degree. C.
