| 用途: | 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. |
