heat of explosion (H2O liq.):
1,5–isomer: 725 kcal/kg = 3031 kJ/kg
1,8–isomer: 732 kcal/kg = 3064 kJ/kg
specific energy: 58 mt/kg = 569 kJ/kg
melting point: 1,5–isomer: 216 °C = 421°F
1,8–isomer: 170 °C = 338°F

This material is prepared by a two-step nitration of naphthalene with
nitric acid. The commercial product, which is a mixture of isomers,
melts above 140 °C = 276°F. It is readily soluble in benzene, xylene,
and acetone and is sparingly soluble in alcohol and ether. It has been
used in French explosive mixtures (schneiderites) as fuel mixed with
ammonium nitrate.
