Procedure

A process for the preparation of styphnic acid comprising adding a liquid suspension containing from about 4 to about 20 percent weight/volume of 2,4-dinitroso resorcinol over a period of time sufficient to form styphnic acid to a nitric acid solution containing between 45 and 100 percent by weight of nitric acid, said solution being maintained at a temperature in the range from about 45° to 100°C.
