실험 절차

The present invention comprises a process for the preparation of 1) diaminodinitropyridine or 2) diaminodinitrobenzene by contacting 1) an aminopyridine or 2) an aminobenzene, respectively, with oleum and nitric acid, wherein the improvement comprises adding at least about 1% molar excess of nitric acid based upon the aminopyridine or aminobenzene respectively, with stirring for at least two hours to form first 1) aminonitropyridine sulfonic acid or 2) aminonitrobenzene sulfonic acid, respectively, and then 1) diaminodinitropyridine or 2) diaminodinitrobenzene respectively.
