Abstract

Tetra substituted ureas wherein at least one substituent is an aryl group have proven very oxidation resistant in the anthraquinone process for making hydrogen peroxide. The urea nitrogen is directly attached to the aryl group. These ureas can be used as a single solvent or as a component of a mixture of solvents.
