  • Patent number: 5246671
    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.
