Abstract: The invention provides a continuous moving bed reactor, useful for the prration of 3,7-diacetyl-1,3,5,7-tetraazabicyclo-3.3.1-nonane (DAPT). The reactor makes novel use of water, a known catalyst for said reaction. However, in this invention, the water is present as ice. The ice is made to automatically promote and moderate the reaction as well as regulate the flow of hexamine into the reactor. These automatic functions are achieved by mixing ice with hexamine, the latter is one of two principle reactants used, to generate a standing bed of slurry. When melted at its base, the slurry advanced under the influence of gravity. The melting of the ice being caused by local application of the second principle reactant, acetic anhydride, which is a liquid.The apparatus is constructed in the following way. A tube shaped reservoir for containing the cited slurry is open at the top end and terminates at its bottom end by a porous compartment. The latter compartment openly retains the slurry. A fluid delivery device, i.

Abstract: An effective amount of 5-nitrobarbituric acid or its trihydrate, when mixed ith molten TNT explosive permits the TNT explosive to set with a fine unoriented crystal structure. In one embodiment, the 5-nitrobarbituric acid or its trihydrate is added to well-stirred liquid TNT at about 100.degree.-110.degree. C. and the mixture is allowed to cool until it stiffens and then is reheated slightly below 85.degree. C. and then cast at about 81.degree. C.

Abstract: Random copolymers are formed by reacting methyl methacrylate and n-octadecyl methacrylate (normal octadecyl methacrylate) at about 75.degree.-80.degree. C in the presence of catalytic amounts of benzoyl peroxide. The mole percentage of the monomer units containing the octadecyl group in the copolymers ranges from 7-21%, the mole percentage of the monomer units originating from methyl methacrylate ranging from 79-93%. The copolymers are useful as moldable lubricants which possess admirable toughness, low friction and low wear.
