METHOD OF OBTAINING 2,4-DINITROPHENOL Russian patent published in 2016 - IPC C07C205/23 C07C201/08

Abstract RU 2572516 C1

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.
