Abstract
A method for synthesizing hydrogen peroxide comprises the steps of: synthesizing an analog of anthraquinone that is miscible or soluble in carbon dioxide; reacting the analog of anthraquinone with hydrogen in carbon dioxide to produce a corresponding analog of tetrahydroquinone; and reacting the analog of tetrahydroquinone with oxygen to produce the hydrogen peroxide and regenerate the analog of anthraquinone. A chemical compound having the formula: wherein R1, R2, R3, R4, R5, R6, R7, and R8 are independently, the same or different, H, RC, or RSRC, wherein RS is a spacer group and RC is a fluoroalkyl group, a fluoroether group, a silicone group, an alkylene oxide group, a fluorinated acrylate group, or a phosphazine group, and wherein at least one of R1, R2, R3, R4, R5, R6, R7, and R8 is not H.
