摘要：
4,4'-dinitrodibenzyls are prepared by reaction of 4-nitrotoluenes, in the presence of an organic solvent and/or diluent, with an alkali metal-alcoholate and/or an alkaline earth metal alcoholate, and subsequent treatment of the reaction mixture with an aqueous solution of hypohalous acids and/or their salts or with chlorine, bromine or an aqueous solution of hydrogen peroxide and/or its salts, or with organic or inorganic peracids and/or their salts.
