Изобретение относитс  к очистке газов от окиси фтора и может быть использовано лрн получении фтореодержащих соединений электрохимическим способом.The invention relates to the purification of gases from fluoride oxide and can be used in the production of fluorinated compounds by electrochemical method.

Известен способ очистки электролизных газов, образующихс  при электрохимическом фторировании, от окиси фтора, состо щий в обработке указанных газов водным раствором йодистого кали  При использЪва.нии данного способа образувцтс -содержащие ионы фтора сточные воды, которые нуждаютс  в очистке,A known method of purification of electrolysis gases formed during electrochemical fluorination, from fluoride oxide, which consists in treating said gases with an aqueous solution of potassium iodide. Using this method of forming fluorine ions containing purification,

Дл  разложени  окиси фтора используют с  дфугие восстановители, например водород , который благодар  высокой энергии активации окиси фтора может быть безопасно смешан с ней. За счет высокой энергии активации окиси фтора (41 ккал/моль) дл  разложени  .её в смеси с водородом требуетс  предварительный нагрев смеси до 200-250 С. Так как .реакци  взаимодействи  окиси фтора с водородом идет с выделением значительного количества тепла, то температура смеси после начала реакции резко возрастает и реакци  становитс  To decompose fluoride oxide, use is made of other reducing agents, such as hydrogen, which, due to the high activation energy of fluorine oxide, can be safely mixed with it. Due to the high activation energy of fluoride oxide (41 kcal / mol), it is necessary to preheat the mixture to 200-250 ° C in decomposition with hydrogen and preheat the mixture. Since the reaction of fluorine oxide with hydrogen proceeds with the release of a significant amount of heat, after the start of the reaction increases dramatically and the reaction becomes

неуправл емой, что приводит к взрыву смеси .uncontrollable, which leads to an explosion of the mixture.

С целью снижени  температуры процесса контактирование окиси фтора с водородом ведут в присутствии активированного угл , обработанного сол ми паллади .In order to reduce the process temperature, the contact of fluoride oxide with hydrogen is carried out in the presence of activated carbon treated with palladium salts.

При этом в качестве активированного угл  используют рекуперационшый уголь с содержанием 0,2% хлористого паллади .At the same time, regenerated carbon with a content of 0.2% palladium chloride is used as activated carbon.

Пример. Электролизные газы, содержащие 0,49 - il,5 об. % окиси фтора i и 80-85% водорода, пропускают при атмосферном давлении через колонку (/диаметр 26 мм, длина 20О мм), снабженную термостатирующей рубашкой. В колонку предварительно загружают активированный уголь в количестве 18, 07 г с добавкой О, 2 вес. % хлористого паллади . Скорость подачи газа в колонку поддерживают в пределах 0,35 7- 1,23 л/мин. При этом эффективность очистки электролизных газов от окиси фтора составила при 35 С - 74%, при 80°С - 97%, при 100°С - 100%, при - 100%.Example. Electrolysis gases containing 0.49 - il, 5 vol. % fluoride oxide i and 80-85% hydrogen, is passed at atmospheric pressure through a column (/ diameter 26 mm, length 20O mm) equipped with a thermostatic jacket. In the column pre-loaded activated carbon in the amount of 18, 07 g with the addition of O, 2 weight. % palladium chloride. The gas feed rate into the column is maintained within 0.35 7-1.33 l / min. At the same time, the cleaning efficiency of electrolysis gases from fluoride oxide was at 35 C - 74%, at 80 ° C - 97%, at 100 ° C - 100%, at - 100%.

В известном способе дл  разложени  окиси фтора водородом требуетс  нагрев смеси до 200-250 С.In a known method, the decomposition of fluoride oxide by hydrogen requires heating the mixture to 200-250 ° C.

Предложенный способ дает возможность , снизить температуру процесса до 100-150 С 5 против 200-250 С по известному.The proposed method makes it possible to reduce the process temperature to 100-150 C 5 against 200-250 C as is known.
