Abstract:
1. A mixture of organic acids and nitric acid prepared by a method comprising the steps of: preparing an aqueous solution of an organic compound, wherein the organic compound is selected from the group consisting of monohydric alcohols, diols, polyols, carbohydrates, and mixtures of carbohydrates; combining, over time, employing a controlled process, in a closed reaction vessel, under a positive pressure of oxygen, the aqueous solution of the organic compound and an aqueous solution of nitric acid to oxidize the organic compound to a mixture of organic acids; maintaining controlled, moderate temperatures of from about 25° C. to about 50° C., controlled positive pressure of oxygen, and controlled agitation of the organic compound and nitric acid reaction mixture during the oxidation reaction; and removing a portion of the nitric acid from the combined aqueous solution to give a mixture of organic acids.
