Studies and Theoretical Optimization of CL‐20 : RDX Cocrystal

Abstract: CL-20 among other nitramines is highly energetic along with the high positive heat of formation, and is a green energetic material employed as solid propellant [1][2][3]. However, it suffers basically from mechanical sensitivity and cost of synthesis. Cocrystallization of CL-20 with other suitable HEMs and LEMs is considered as the best crystal engineering technique to reduce its sensitivity [2,[4][5][6] as it masks crystal defects which in turn are responsible for mechanical sensitivity. The present investiga… Show more

“…Some reports in the literature on the synthesis of CL-20 cocrystals with other nitramines include the following: CL-20/HMX cocrystals and CL-20/RDX cocrystals. From the reported results, CL-20/RDX cocrystals are usually formed in ratios of 1:1 and 1:2 via EM and GM methods, which was confirmed on the basis of spectral and other analytical techniques. The formation of CL-20/RDX cocrystals is driven by C–H···O hydrogen bonds between -NO 2 and −CH 2 .…”

“…The particles obtained by GM method are near-spherical and of uniform size, 96 and the other cocrystal morphology clearly shows the sharpness of CL-20 crystal edges being masked and distortion in the orthorhombic structure. 95 In addition, though new crystal phases were presented in the XRD pattern of CL-20/RDX cocrystal, the single crystal data need to be further studied to confirm the refined crystal structure.…”

“…It is interesting to observe that the higher number of NO 2 groups is not only the sole contributing effect for oxidation, while the bonding and arrangement of the NO 2 groups also gives a reasonable explanation to the quencher efficiency. Hence from the observation of the Figure S1(c,d) for CL‐20 and Cocrystal, it may be attributed that all the NO 2 groups are not involved in quenching, which is viewed from the structural configuration of N‐NO 2 groups in CL‐20 and Cocrystal which are not planar and moreover are stressed 61 while in RDX the NO 2 groups are planar suggesting better interaction between the HEM and CSA(PANi).…”

“…CL-20 is the most powerful green energetic material compared to RDX and TNT [16]. Whereas CL-20: RDX Cocrystals are the next generation energetic materials with improved characteristics without affecting the energy of its sub crystals [17]. The doped polyaniline is a conjugated polymer that acts as a fluorophore and show a molecular wire effect during fluorescence quenching studies.…”
