“…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:…”

“…Recently, it has been reported that differential scanning calorimetry (DSC) technique allows more accurate and rapid characterisation of any kind of phase change [9,[15][16][17][18][19]. Thus, it seemed interesting to use the DSC technique for the determination of SLE of complex systems including the stabilizers diphenylamine, ethyl centralite, methyl centralite and their derivatives.…”

This work compares the hitherto unknown crystal structure of N‐methylnitramine with its gas‐phase diffraction structure. A series of alkaline, alkaline earth and some transition‐metal salts were investigated. Furthermore, a series of new nitrogen‐rich salts was synthesized and characterized for the first time. The Mannich reaction of N‐methylnitramine with formaldehyde yields 2‐nitro‐2‐azapropanol, which was treated with 2‐nitro‐2‐azapropyl isocyanate to furnish new bis‐N,O‐(2‐nitro‐2‐azapropyl)carbamate. The analogue bis‐N,N′‐(2‐nitro‐2‐azapropyl)urea derivative is formed when 2‐nitro‐2‐azapropyl isocyanate is treated with water. Owing to the energetic nature of all compounds, their energetic properties were determined. The sensitivities towards impact, friction and electrostatic discharge were determined using the BAM drophammer and friction tester as well as a small‐scale electrical discharge device. Standard enthalpies of formation were calculated at the CBS‐4M level of theory. With these values and the experimental densities, several detonation parameters such as detonation pressure and velocity of the compounds were computed using the EXPLO5 (V6.01) computer code and compared to currently used explosives.

Solid–Liquid Equilibria for the Binary Systems Naphthalene or Biphenyl + 1-Tetradecanol or + 1-Hexadecanol

A differential scanning calorimetric technique has been used to obtain solid-liquid equilibrium temperatures for the mixtures naphthalene or biphenyl + 1-tetradecanol, or + 1hexadecanol. All the systems show a simple eutectic point, whose final composition was determined by means of the Tamman's plots using the needed values of the eutectic heat and of the heat of melting, which are also reported. DISQUAC interaction parameters for the OH/aromatic contacts in the selected systems are given. The present experimental SLE phase diagrams are similarly described by DISQUAC and UNIFAC (Dortmund) models. However, the comparison of DISQUAC and UNIFAC results for systems involving naphthalene and shorter 1-alkanols (methanol-1-octanol) reveals that the temperature dependence of the interaction parameters is more suitable in DISQUAC. The systems are also investigated in terms of the concentration-concentration structure factor. It is shown that the positive deviations from the Raoult's law of the studied solutions become weaker when the homocoordination decreases.
