一般描述

1,3-Diethyl-1,3-diphenylurea is a symmetrical derivative of urea.1 1,3-Diethyl-1,3-diphenylurea is a commonly employed as stabilizer in double-base propellants. Molecule of 1,3-diethyl-1,3-diphenylurea exhibits non-crystallographic C2 symmetry. Photochemically induced fluorescence (PIF) studies of 1,3-diethyl-1,3-diphenylurea as stabilizer has been reported . 1,3-Diethyl-l,3-diphenylurea (Ethylcentralite or EC) has been reported as propellant stabilizer degradation derivative. Effect of ethyl centralite on a cyclotrimethylenetrinitramine (RDX)-based polymer-bonded explosive (PBX) has been reported.

The photochemically induced fluorescence (PIF) studies of 1,3-diethyl-1,3-diphenylurea or ethyl centralite (EC) as stabilizer have been carried out under various conditions. Influences of solvent type (water, methanol, acetonitrile and chloroform), oxygen dependence and UV irradiation time on the spectroscopic properties

The increasing demand for rapid methods to identify both inorganic and organic gunshot residues (IGSR and OGSR) makes electrochemical methods, an attractive screening tool to modernize current practice. Our research group has previously demonstrated that electrochemical screening of GSR samples

The mol-ecule of the title compound, C(17)H(20)N(2)O, a symmetrical derivative of urea, shows non-crystallographic C(2) symmetry. Inter-action with the aromatic system of the phenyl substituents as well as amide-type resonance is responsible for the marked planarization of the coordination environments

Propellants containing nitrate esters need stabilizers to avoid early decomposition or even explosion during storage. Newly prepared malonanilides M1-M5 were tested in stabilizing double-base propellants (DBPs). Their stabilization was compared with the effect of classical stabilizer N,N'-diethyldiphenyl urea (C1) using
