The progress of the identification of the impurities in FEFO is discussed. One very high boiler has been partially isolated from a sample of concentrated impurities. Mass spectra of five of the low boiling impurities are reported. Heats of fusion for PETN, washed PETN and PETN extracted from Extex are discussed. A standard deviation of less than 1% for the heat at fusion of PETN by DSC-1 is obtained. High pressure DTA thermograms are reported for HMX, PETN, Tetryl and TNT
