2,6‐Diarylmethylene‐thiazolo[3,2‐a]pyrimidine‐3,5,7‐triones as Stabilizers for Double‐Base Propellant

Abstract

2,6‐Diphenylmcthylene‐thiazolo‐pyrimidine‐trione, the o‐, m‐, and p‐nitrophenyl‐derivatives were prepared and incorporated as stabilizers in a double base smokeless powder. The prepared powders were subjected to some standard qualitative and quantitative stability tests. It was found that the 2,6 diphenyl trione (Ia) has a good stabilizing effect for double‐base propellants.

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

“…1) show superior properties as stabilizers for DBPs in comparison with the classical ones [31][32][33][34]. The acidity of these molecules could favor their use as stabilizers for DBPs.…”

Preparation and thermal performance of nitrocellulose coated by polydopamine

“…These substances react with nitrogen oxides to form a series of nitrosamine compounds, which affect human life safety and cause environmental pollution problems 9,10 . Therefore, in the past few decades, researchers have developed kinds of stabilizers, such as triphenylamine, 11 ketones, 12,13 polymer, 14,15 phenols, 10,16 and natural extracts, 2,17 to meet the requirements of “green” propellants.…”
