Abstract
A process for co-producing hydrogen peroxide and another useful product, namely either an oxalate ester or a carbonate ester product, is provided. The process comprises reacting a saturated monohydric alcohol with carbon monoxide and a quinone to form an oxalate ester or a carbonate ester product and hydroquinone. The hydroquinone is then reacted with oxygen to form hydrogen peroxide and a quinone. The quinone from the second reaction can be recycled to the alcohol-carbon monoxide first reaction.
