摘要:
A method producing a surfactant from glycerol by converting glycerol, in a first step, to glycidol, polymerizing glycidol to an aliphatic alcohol and finally substituting a hydroxyl group with a substitute anion.
摘要:
A method for the retraction of an explosive component from a high explosive, including the steps of loading a high explosive containing an explosive component into an striping down vessel; supplying a supercritical fluid to the striping down vessel; contacting the high explosive with the supercritical fluid at a temperature below the melting point of the explosive component and at a pressure sufficient to strip down the explosive component; and inducing a sonicating process on the striping down vessel simultaneously at a frequency of 2 MHz to 10 MHz.

摘要:
A highly energetic, high-oxygen carrier suitable as high-performing green replacement for ammonium perchlorate includes halogen-free ionic salts consisting of fuel cations and over-oxidized anions containing multiple nitro- or nitromethyl-substituted azolyl ligands. The over-oxidized anions include a central atom selected from the group consisting of boron, aluminum, or gallium. Characteristically, the carrier has sufficient amounts of oxygen for complete or near complete combustion of the over-oxidized anions, the fuel cations, metal additives and binders.
