“…The determination of cyclo-1,3,5-trimethylene-2,4,6-trinitramine (RDX) and cyclo-1,3,5,7-tetramethylene-2,4,6,8-tetranitramine (HMX) is dif®cult because of their close structural similarity (1) . The study of the mechanism of formation of the high explosive RDX in the nitrolysis of hexamethylenetetramine results in the discovery of a number of compounds with related structures which are possible intermediates and by-products in the reaction (2) . The presence of some of these compounds even in small quantities in commercial production lots of hexogen may produce desirable and undesirable effects (2) .…”

“…But the dependence of the amount of HNO 3 yielded from RDX on RDX concentration in 97.5% H 2 SO 4 and on the size of the RDX crystals are limiting this method (5) . A chromatographic (2) and an infrared method (1) have been described, but they are of limited use. So far the analysis of both RDX and HMX has mainly been accomplished by HPLC (6,7) .…”

The UV‐absorption spectra of cyclo‐1,3,5‐trimethylene‐2,4,6‐trinitramine (RDX) and cyclo‐1,3,5,7‐tetramethylene‐2,4,6,8‐tetranitra mine (HMX) are strongly overlapping and do not allow their direct determination without previous separation by conventional methods. A partial least squares method (PLS) in a multicomponent analysis provides a sensitive and accurate technique for the analysis of complex mixtures with strong overlapping spectra. The experimental calibration matrix was designed with 15 samples. The concentration varied between 0.584 μg/ml and 10.220 μg/ml for HMX, and between 0.400 μg/ml and 8.000 μg/ml for RDX. The cross‐validation method was used to select the number of factors. To check the accuracy of the proposed method, the optimized model obtained by using PLS‐2 was applied to the determination of these compounds in industrial samples.

“…Bonhomme (2), Duvckaerts (5, 10), and Jones (8) have reported on the relationship between particle size and absorbance of the material incorporated in the disk. Others (3,4,7) have discussed the use of the disk technique for specific analyses. This paper describes the application of the pressed disk technique to a rapid determination of isomer distribution in mixtures of o-, m-, and p-dicyanobenzene.…”
