ABSTRACT:
A method for separating an aqueous solution which contains minor amounts of nitrated esters which are only slightly soluble in water is provided. Separation of the nitrated esters, which include ethylene glycol dinitrate and nitroglycerin, is effected by contacting the aqueous solution with an organic phase of ethylene glycol dinitrate for a period of time sufficient to allow extraction of the nitroglycerin in solution into the ethylene glycol dinitrate phase. The organic ethylene glycol dinitrate phase is then separated from the aqueous solution, and the latter is distilled at a temperature of from about 50 degrees F. to about 200 degrees F. at a lower than atmospheric pressure. Upon completion of the separation process water, which is substantially free of nitrated esters, is suitable for discharge and return to a natural environment.
