Polynitrobiphenyl derivate
Searching at the US Patent Office i find this patent 4,935,544, which illustrates the synthesis of a high energy explosive compound.
Example I
In a preparation without the use of catalist 50 g of 2,2´,6,6-´tetranitrobenzidine is dissolved in 2000mL of 100% H2SO4. After s sufficient period
of time dissolving the reactants, an acis mixture containing 130 mL of 90% HNO3 and 200 mL of of 96% H2SO4 is added. While stirring, this mixture is
heated rapidly to 70°C and held at that temperature for a period of time from about 1 to 2.5 hours. This reaction mixture is then cooled rapidly to
0° to -25°C and stirred for a period of time from about 0.5 t 2 hours. The mixture is filtered, and the solid is washed successively with conc.
H2SO4, 50% H2SO4 and 1N aqueus HCl. This product is then dried to yield 47.8 g of Octanitrobenzidine.
Yellow-orange needles.
MP 280° - 290°C (Unrecrystallized)
MP 310°C (Recrystallized from acetonitrile)
MW. 544.23
%N 25.74
Density 1.82 g/cm3
Impact Sensitivity 95 cm (2.5 Kg weight)
Det. Vel. (Clac´d) 8,300 m/sec
