Abstract: A method in the recovery of trinitromethane in the form of an aqueous solution from a solution containing nitric acid, water and trinitromethane, the solution containing a smaller quantity of nitric acid than that corresponding to the nitric acid content of an azeotropic mixture of nitric acid, water and trinitromethane, wherein it is ensured that the solution contains so much water that the distilled mixture of trinitromethane and water obtains a content of approximately 35 % or lower trinitromethane and a content of approximately 65 % or more water, and the remaining nitric acid solution obtains a composition of approximately 67 % nitric acid (HNO3) and approximately 33 % water (maximum azeotrope in the system nitric acid-water).
