Abstract
A process for producing hydrogen peroxide wherein a gaseous mixture comprising hydrogen and oxygen is contacted with a catalyst in the presence of water and an organic solvent wherein: PA1 (i) the organic solvent is immiscible with water and unreactive with hydrogen peroxide under the contacting conditions; PA1 (ii) the distribution coefficient for hydrogen peroxide between the water and the organic solvent is greater than 1; PA1 (iii) the catalyst is of the formula L.sub.2 MX.sub.2 wherein L is a ligand represented by the formula A R.sub.1 R.sub.2 R.sub.3 wherein R.sub.1 R.sub.2 and R.sub.3 are alkyl, cycloalkyl or aryl groups, hydrogen or halogen, A is a Group 5b element selected from the group consisting of nitrogen, phosphorous and arsenic, M is a Group 8 metal and X is halogen, said catalyst being soluble in said organic solvent and insoluble in water; and PA1 (iv) the gaseous mixture is non-ignitable under the process conditions characterized in that the organic solvent is selected from the group consisting of fluorocarbons, halofluorocarbons and mixtures thereof.
