A process and apparatus for the production of hydrogen peroxide directly from hydrogen and oxygen utilizing a pipeline reactor for establishing a reaction zone for the reaction of these gases within an acidic aqueous solution, is disclosed. The reaction zone is completely filled with the solution and a reaction mixture is formed by dispersing hydrogen gas and oxygen gas in the solution in proportions above the lower flammability limit under control conditions resulting in the formation of hydrogen peroxide. This reaction mixture is maintained until the proportion of hydrogen has decreased to below the lower flammability limit for the gas mixture. The hydrogen peroxide is then removed from the reaction zone. The reaction of the hydrogen and oxygen in the solution is conducted under plug-flow conditions.

Process for the production of hydrogen peroxide from hydrogen and oxygen

An improved process for directly producing hydrogen peroxide from oxygen and hydrogen is disclosed. Hydrogen and oxygen are contacted in the presence of a catalyst, acid, halide ions and a multifunctional phosphonate or phosphate preparation so as to increase hydrogen peroxide yield and decrease catalyst deactivation.
