Abstract
Procedure for the preparation, by direct nitration, of dinitrophendes of the general formula **(See formula)** where R represents a hydrogen atom, a straight chain or branched alkyl moiety containing 1 to 8 carbon atoms, or a cycloalkyl, phenyl or benzyl moiety optionally substituted by an alkyl moiety of 1 to 4 carbon atoms, or by a halogen atom, characterized by being treated, at a temperature maintained between 40º and 80ºC. and stirring, an aqueous solution of an alkali metal phenolate of the formula **(See formula)** where R has the meaning indicated above and where M represents an alkali metal atom, with an aqueous nitric acid solution leading to a nitric acid content in the reaction mixture of 10 to 50% by weight.
