Abstract:
1. A method of preparing a deicing composition, the method comprising: a) preparing an aqueous solution of at least one organic compound suitable for nitric acid oxidation; b) combining, over time, the aqueous solution of the at least one organic compound and an aqueous solution of nitric acid to oxidize the at least one organic compound to a mixture of organic acids; c) removing a portion of the nitric acid from the combined aqueous solution through an evaporation process; and d) making basic with at least one base the solution from which nitric acid has been removed to convert residual nitric acid to inorganic nitrate and to convert the mixture of organic acids to a mixture of organic acid salts; wherein a deicing agent is combined with the residual inorganic nitrate and the mixture of organic acid salts.
