1,3-Diethyl-1,3-diphenyl-urea.
Acta Crystallogr. Sect. E Struct. Rep. Online 67(4) , o827-o827, (2011) 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 pl... |

Photochemically induced fluorescence studies of 1,3-diethyl-1,3-diphenylurea as stabilizer and its quantitative determination.
Forensic Sci. Int. 240 , 35-40, (2014) 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 dep... |

New protocol for the isolation of nitrocellulose from gunpowders: utility in their identification.
Talanta 81(4-5) , 1742-9, (2010) In this work, a new approach for the isolation of nitrocellulose from smokeless gunpowders has been developed. A multistep solvent extraction method was needed to purify nitrocellulose contained in gunpowders. For single-base or double-base gunpowders six con... |

Stability studies of double-base propellants with centralite and malonanilide stabilizers using MO calculations in comparison to thermal studies.
J. Hazard. Mater. 179(1-3) , 453-61, (2010) 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 effec... |

Evaluation of malonanilides as new stabilizers for double-base propellants.
J. Hazard. Mater. 73(3) , 237-44, (2000) Five malonanilide derivatives (M1-M5) were prepared by the reaction of ethyl malonate with aniline derivatives. These compounds were investigated as new stabilizers for double-base propellants (DBPs). The evaluation process has been performed through thermal ... |
