Experimental Method for Determination of the Rate of Evaporation of 2,4, 6-Trinitrotoluene (TNT) and 2,4-Dinitrotoluene (2,4-DNT)
Abstract
The rate of evaporation of 1,3,5-trinitrotoluene (TNT) and 2,4- dinitrotoluene (DNT) into air under ambient conditions was determined. This was accomplished by making cast pipes of TNT and 2,4-DNT. Nitrogen was passed through a pipe and then through a cold trap. The trap contained 0.5 mL of methanol and was chilled in an ice bath. The nitrogen flow rate (mL/min) through the pipe and trap was measured and after a specified amount of time the trap was disconnected and the methanol was removed. The concentration of TNT or 2,4-DNT in the methanol was determined by high performance liquid chromatography (HPLC) analysis. From the mass of TNT or 2,4-DNT found, mean flow rate of nitrogen through the apparatus, and the length of time for a run, the rate of evaporation as grams per minute per square centimeter (g min cm- ) was calculated. This data was used to validate Griffy's theoretical model for determining the evaporation rate of TNT....
