Selig, W; Crossman, G L

PETN in the composites LX-08, LX-13, XTX-8003, and LX-02-1 was determined by a titrimetric micromethod. The method is based on the reduction of the nitrate group with ferrous ion in concentrated sulfuric acid. Sample size was from 2 to 5 mg. The titrant was approximately 0.01 N ferrous ammonium sulfate in 1:1 sulfuric acid. None of the other ingredients in the above-mentioned composites interfered. A Sargent Model D recording titrator with a platinum/mercurous sulfate electrode system was used. With the Tektronix 4051 graphics system as little as 300 ..mu..g of PETN can be determined with good precision.
