shows the production process and the con-
sumption of raw materials for producing 100 kg glycerine dinitrate is listed in
Table
5.23
.
The side products in the reaction include 200 kg ammonium nitrate and 165 kg
calcium sulfate.
The cost of production of glycerine dinitrate by this method is slightly lower
than the method of nitroglycerine as a raw material (Table
5.24
).
