Stability studies of double-base propellants with centralite and malonanilide stabilizers using MO calculations in comparison to thermal studies

DSC measurement and prediction of phase diagrams for binary mixtures of energetic materials’ stabilizers

“…composition can be significantly improved using the method proposed by Matsuoka and Ozawa [31], often used in the literature [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23]. This method is based on the assumption that the eutectic fraction is defined as:…”

“…Excellent research by the world's scientific community has focused on hazardous materials, without sufficiently investigating the nature of the reactions which can occur between stabilizers in the energetic material [7,[10][11][12]. The thermodynamic properties and structural details of these mixtures have received much less attention.…”

Solid + liquid equilibria and molecular structure studies of binary mixtures for nitrate ester’s stabilizers: Measurement and modeling

“…Numerous research studies devoted to the stabilization of nitrate esters have been conducted without sufficiently elucidating the chemical reactions that can occur between the stabilizers in the energetic material [6][7][8][9], but less attention has been paid to their thermodynamic properties and structural details. In this context, within the last ten years, several studies have been carried out by our research group with conclusive and interesting results [3,[10][11][12].…”

Enhancement of stabilizing properties of double-base propellants using nano-scale inorganic compounds

“…In a series of researches extending over long period Marqueyrol and his co-workers [1][2][3][4] have determined the stabilizing effect of various substances particularly naphthalene, mononitronaphthalene, N,N-biphenyl benzamide, carbazol, diphenylamine and diphenylnitrosoamine. Recently many other organic stabilizers for double-base propellants (DBPs) were used such as; malonanilides [5,10], acrylamido polymers [6], poly N-(4-chlorophenyl) and poly N-(4-methylphenyl) acrylamides [7], 5-phenyl-cyclohexane-1,3-dione-4-carboxyanilide [8] and 2,4,6-triphenyl-thiazolo-(3,2-a)-s-triazine [9]. Propellants consisting of nitrocellulose (NC) and/or other nitrate esters are inherently chemically unstable and undergo decomposition even under standard storage conditions.…”

“…Recently in this lab [5,10] thermal analysis techniques (TGA and DSC) together with molecular orbital calculations were introduced as a second tool for evaluation of the double-base propellant stabilizers.…”
