Abstract
Amine salts of dinitroalkyl phenols have been suggested as herbicides and insecticides. A selection of such amine salts was examined as to their suitability for characterizing dinitroalkyl phenols. The following new salts are described: the piperidine, morpholine, and cyclohexylamine salts of each of 2,4-dinitrophenol, 4,6-dinitro-2-methylphenol, 2,6-dinitro-4-methylphenol, 4,6-dinitro-2-isopropylphenol, 2,6-dinitro-4-isopropyl phenol, 4,6-dinitro-2-(sec-butyl)-phenol, 2,6-dinitro-4-(tert-butyl)-phenol, and 2,6-dinitro-4-(tert-amyl)-phenol. In addition, the preparation of 4,6-dinitro-2-isopropylphenol and 2,6-dinitro-4-isopropylphenol does not appear to have been previously described. The use of these salts, and similar ones with other amines, is recommended for the preparation of crystalline derivatives of dinitrophenols.
