Supercritical antisolvent micronization of cyclotrimethylenetrinitramin / Byoung-Min Lee in Industrial & engineering chemistry research, Vol. 48 N° 24 (Décembre 2009) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 48 N° 24 (Décembre 2009) . - pp. 11162–11167 Titre : Supercritical antisolvent micronization of cyclotrimethylenetrinitramin : influence of the organic solvent Type de document : texte imprimé Auteurs : Byoung-Min Lee, Auteur ; Jin-Seong Jeong, Auteur ; Young-Ho Lee, Auteur Année de publication : 2010 Article en page(s) : pp. 11162–11167 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Supercritical--Antisolvent--Micronization--Cyclotrimethylenetrinitramin--Influence--Organic--Solvent Résumé : A supercritical antisolvent (SAS) process was used to prepare micronized cyclotrimethylenetrinitramin (RDX). This study examined the influence of different solvents at a fixed temperature (50 °C) and pressure (13.7 or 15 MPa) on the morphology, particle size (PS), and particle size distribution (PSD) using a semicontinuous SAS process. Dimethyl sulfoxide (DMSO), dimethylformamide (DMF), acetone (AC), acetonitrile (ACN), n-methyl 2-pyrrolidone (NMP), and cyclohexanone (CHN) were used as solvents. The recrystallized RDX particles were characterized by scanning electron microscopy (SEM), particle size analyzer (PSA), Fourier transform infrared (FT-IR) spectroscopy, and differential scanning calorimetry (DSC). Depending on the solvent used, the recrystallized RDX particles showed a variety of morphologies, particle sizes, and particle size distributions (PSD). The mean particle size of the recrystallized RDX ranged from 2.6 to 17.7 μm. The enthalpy change (ΔH = 583.4, 847.7, 967.1, 823.9, 1131, and 1620 J/g) for the exothermic decomposition of recrystallized RDX was much higher than that of the unprocessed RDX (ΔH = 381.5 J/g).
