Dosage du polymorphisme : spectrométrie IRTF et chimiométrie. Application aux formes polymorphes du CL20 (Hexaazahexanitroisowurtzitane / HNIW).

Abstract : HexaazahexaNitroIsoWurtzitane (or HNIW) hexanitred derivate, still called CL20, is a new highly energy molecule, which presents four polymorphic forms : α, β, γ and ε. Is the form ε most active and marketing stipulates to provide a product of which content of form ε that is to say higher than 95%, with estimate of the contents of the other forms as well as majority im-purity (pentanitred derivative). The aim of this work is on the one hand to characterize the four formes polymorphes, and on the other hand to develop, to optimize and validate a new quantitative analytical method to measure polymorphic composition of the CL20 by coupling IRTF (MIR) spectrometry/chemometric, respecting the technical and commercial require-ments, and transferable on factory site. The chemometric methods are used to conceive the experimentation and to process the experimental data necessary (calibration and validation).
