The report completes the technical, operating and economic studies for a 3-year pilot plant demonstration of the ureaammonium nitrate UAN route to guanidine nitrate GN as an intermediate for manufacture of nitroguanidine NQ. It summarizes the 1973 effort, including plant modifications, production of 10 tons of specification GN, economic comparison of the UAN and British Aqueous Fusion BAF processes for GN, and layaway of the GN pilot plant. An economic catalyst Houdry CP-532 silica bead lifetime was shown in the reactors which are basically production prototypes in design and size. The concept of the UAN process for manufacturing GN via a melt reactor plus a single aqueous crystallization step was demonstrated.
