    Abstract: PROBLEM TO BE SOLVED: To provide a simple method for producing 1,5-dinitronaphthalene by reducing or eliminating existing problems.
    SOLUTION: This method for producing the 1,5-dinitronaphthalene comprises nitrating naphthalene with 72-87 mass% concentration nitric acid in the absence of sulfuric acid at 30-80°C, filtering the nitrated naphthalene at 5-20°C, washing the obtained solid precipitated material with water, and then washing with acetone to isolate the 1,5-dinitronaphthalene.
