Patent ID: 7147833

Claim:
A process for producing a solution of hydrogen peroxide in an organic medium by reaction of hydrogen and oxygen in the presence of a catalyst in said organic medium, comprising the steps of: (a) establishing a continuous flow of a liquid phase reaction medium in an elongated reaction zone formed by a plurality of pipe sections in communication with each other, said liquid phase reaction medium comprising an organic compound in the presence of a catalyst for said reaction, and at least one of the pipe sections of the elongated reaction zone includes a plurality of tubes upon which the catalyst is fixed, said tubes being arranged within the elongated reaction zone such that portions of the liquid phase reaction medium flow through said tubes; (b) introducing a reactive feed of oxygen and hydrogen into said continuously flowing liquid phase reaction medium to form hydrogen peroxide within said liquid phase reaction medium; and (c) separating unreacted gases from said liquid phase reaction medium containing hydrogen peroxide.
