La voie de Hexamine � HMX est longue et comprend de nombreux compos�s interm�diaires. Le dinitrate d'hexamine et le dinitropentam�thyl�ne t�tramine (DPT) sont deux de ces interm�diaires. La solubilit� limit�e des interm�diaires mentionn�s ci-dessus affaiblit l'applicabilit� des mod�les cin�tiques ordinaires du premier et du deuxi�me ordre � l'�tape de d�composition dans laquelle le Dinitrate d'hexamine a �t� converti en DPT. Le coefficient de corr�lation avec l'ajustement du premier ordre �tait l�g�rement sup�rieur � celui correspondant � l'ajustement du deuxi�me ordre. Ce r�sultat signifie que la r�action mentionn�e est probablement de premier ordre, mais l'ajustement a d� �tre refait selon les mod�les fluide-particules afin de prendre en compte l'h�t�rog�n�it� du m�lange �tudi�. Les mod�les cin�tiques contr�lant la diffusion n'�taient pas tr�s coh�rents avec les r�sultats exp�rimentaux. Le mod�le de contr�le de la r�action de surface �tait plus �troitement coh�rent avec les r�sultats exp�rimentaux. L'�nergie d'activation a �t� trouv�e dans la c�l�bre parcelle d'Arrhenius. Pour la conversion du dinitrate d'hexamine en DPT dans les conditions non aqueuses adopt�es, l'�nergie d'activation �tait de 84 kJ/mole, ce qui signifie que la vitesse de r�action peut �tre doubl�e ou tripl�e pour chaque dix degr�s.

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The pathway from Hexamine to HMX is long and includes many intermediate compounds. Hexamine Dinitrate and Dinitropentamethylene Tetramine (DPT) are two of these intermediates. The limited solubility of the above mentioned intermediates weaken the applicability of the ordinary first and second order kinetic models on the decomposition step in which Hexamine Dinitrate was converted into DPT. The correlation coefficient with the first order fit was somewhat higher than that corresponding to the second order fit. This result means that the mentioned reaction is probably first order but fitting had to be redone according to the fluid - particle models in order to consider the heterogeneity of the investigated mixture. The diffusion controlling kinetic models were not highly consistent with the experimental results.The surface reaction controlling model was more tightly consistent with the experimental findings. The activation energy was found from the famous Arrhenius plot. For the conversion of hexamine dinitrate into DPT under the adopted non - aqueous conditions, the activation energy was 84kJ/mole, which means that the reaction rate may be doubled or tripled for each ten degrees. 108 pp. Englisch.
