Abstract
1. 2,4,7-Тринитрофлуорен структурной формулыв качестве промежуточного соединения в синтезе 2,4,7-тринитрофлуоренона.2. Способ получения 2,4,7-тринитрофлуорена, отличающийся тем, что флуорен обрабатывают концентрированной азотной кислотой при 0-25°С при мольном соотношении флуорен:азотная кислота 1:30-1:50 с последующим выделением целевого продукта известными приемами.3. Способ получения 2,4,7-тринитрофлуоренона из производственного флуорена, отличающийся тем, что, с целью увеличения выхода целевого продукта и упрощения процесса, в качестве производного флуорена берут 2,4,7-тринитрофлуорен и окисляют его бихроматом натрия или калия в уксусной кислоте.4. Способ получения 2,4,7-тринитрофлуоренона из флуорена реакциями нитрования и окисления, отличающийся тем, что, с целью увеличения выхода целевого продукта и упрощения процесса, флуорен нитруют до 2,4,7-тринитрофлуорена, и реакционную смесь, предварительно разбавив водной уксусной кислотой, окисляют добавлением бихромата калия или натрия с последующим выделением целевого продукта известными приемами.1. 2,4,7-Trinitrofluorene structural formulas as an intermediate in the synthesis of 2,4,7-trinitrofluorenone. The method of obtaining 2,4,7-trinitrofluorene, characterized in that fluorene is treated with concentrated nitric acid at 0-25 ° C at a molar ratio of fluorene: nitric acid of 1: 30-1: 50, followed by separation of the target product by known methods. The method of obtaining 2,4,7-trinitrofluorenone from production fluorene, characterized in that, in order to increase the yield of the target product and simplify the process, take 2,4,7-trinitrofluoren as a fluorene derivative and oxidize it with sodium or potassium bichromate in acetic acid .four. The method of obtaining 2,4,7-trinitrofluorenone from fluorene by nitration and oxidation reactions, characterized in that, in order to increase the yield of the target product and simplify the process, fluorenate to 2,4,7-trinitrofluorene, and the reaction mixture, previously diluted with aqueous acetic acid, oxidized by the addition of potassium or sodium bichromate, followed by separation of the target product by known methods.
