DEP

DEP (falone, 19), a mixture of tris[2-(2,4-dichlorophenoxy)ethyl]phosphite and bis[2-(2,4-dichlorophenoxy)ethyl]phosphite is prepared by the reaction of 2,5-dichlorophenoxyethanol with phosphorus trichloride in the presence of pyridine.

Super-rate burning occurs when lithium fluoride (LiF) is incorporated into NC-NG or NC-TMETN double-base propellants. As shown in Fig. 6.27, the burning rate of a propellant catalyzed with 2.4% LiF and 0.1% C increases drastically in the pressure region between 0.3 MPa and 0.5 MPa. This super-rate burning effect diminishes gradually as the pressure is increased above 0.5 MPa. The non-cata-lyzed propellant is a conventional NC-NG double-base propellant composed of 55 % NC, 35% NG, and 10% DEP. The maximum burning rate increase is about 230% at 0.5 MPa.

ICEP can also contribute to the rotation of polarizable particles with elongated shapes [2, 4, 5, 15], as illustrated in Pig. 2a. It is well known that DEP causes such particles to align with the axis of a uniform field, due to electrostatic torque on the induced dipole. At low AC...
