FIELD: chemistry.SUBSTANCE: method is realised by phenol dissolution in reagent, which is prepared by mixing concentrated nitric acid and solvent, with the following heating for specified time. Method is characterised by the fact that as solvent applied is dioxane, and reaction is carried out at temperature 70-80°C for 10-60 min.EFFECT: method makes it possible to considerably accelerate reaction and reduce temperature of synthesis realisation, and reach practically quantitative conversion of phenol into 2,4-dinitrophenol.1 tbl, 10 ex |
