tometry was developed for the determination of small amounts of dipentaerythritol hexanitrate (DPEHN) in pentaerythritol tetranitrate (PETN). The method involved preparing a 15% solution of the sample in methyl cyanide: measuring the absorbance of this solution at the peak of the 8.9-micron band using a 1.0 mm rock salt cell: and instrumental compensation of the cell, solvent, and PETN. The net absorbance was converted to percent DPEHN by the use of a previously established relationship between absorbance and concentration. This relationship had been established with standards. The developed method is applicable to the determination of as low as a few tenths of one percent as well as higher percentages of DPEHN in PETN with a precision of about 0.1%. (auth)
