Abstract
This paper describes the results of the chemical analysis of different so called insensitive RDX samples. The materials are to be said to react insensitive in the GAP-test when they are used as ingredients in specific formulations. The true reasons for this insensitivity are not clearly understood until now.
The properties of e.g. explosive particles produced by crystallisation processes could be influenced by the inclusion and / or adsorption of residual solvent moelcules. The used type of solvent or antisolvent determines the crystal form which possibly decides about / influences the mechanical and thermal sensitivity of the substances. Furthermore the addition of suitable components like plastizers or coating materials may influence the sensitivity of explosives.
Objective of the paper was to chemically characterize different i-RDX-samples by different analytical techniques (IR, HPLC, GC-MSD) in order to get a first view of the compositions of the samples and possibly to identify similarities or differences between the charges. Furthermore suitable conditions for the SPME enrichment technique (solid phase micro extraction) should be tested the effective enrichment of possible residual solvents in so called insensitive RDX charges which are delivered / sold by different suppliers.
