Description
Известен способ получени 1,2-дихлордекафторциклогексана действием на о-дихлорбензол трехфтористым кобальтом при 350° С.A known method for producing 1,2-dichlordecafluorocyclohexane by acting on o-dichlorobenzene with cobalt trifluoride at 350 ° C.
Предложенный способ отличаетс тем, что на 1,2-дихлороктафторциклогексан действуют элементарным фтором, разбавленным азотом при 50-60° С. Благодар этому увеличиваетс выход продукта до 60,5%.The proposed method is characterized in that 1,2-dichloro-octafluorocyclohexane is treated with elemental fluorine diluted with nitrogen at 50-60 ° C. Due to this, the yield of the product is increased to 60.5%.
Пример. В трехгорлую коническую колбу емкостью около 250 мл, снабженную механической мешалкой и обратным холодильником, помещают 147,5 г (0,5 моль) 1,2-дихлороктафторциклогексана; затем содержимое колбы нагревают на вод ной бане до 50-60°С и по достижении этой температуры при энергичном перемешивании пропускают со скоростью 0,20- 0,25 г/час рассчитанное количество фтора, разбавленного азотом (1:4). Указанную температуру поддерживают в течение всей реакции.Example. In a three-necked conical flask with a capacity of about 250 ml, equipped with a mechanical stirrer and reflux condenser, 147.5 g (0.5 mol) of 1,2-dichlorooctofluorocyclohexane are placed; then the contents of the flask are heated in a water bath to 50-60 ° С and upon reaching this temperature with vigorous stirring, the calculated amount of fluorine diluted with nitrogen (1: 4) is passed at a rate of 0.20-0.25 g / hour. This temperature is maintained throughout the reaction.
По окончании пропускани необходимого количества фтора реакционную смесь перегон ют , собирают фракцию, кип щую при 107- 110° С. Выход 89,2 г (60,5%). После дополнительной очистки 2-3-кратной сублимацией полученное вещество имеет т. кип. ,5° С и т. пл. 33-39,5° С.At the end of passing the required amount of fluorine, the reaction mixture is distilled; a fraction boiling at 107-110 ° C is collected. Yield 89.2 g (60.5%). After additional purification by 2-3 sublimations, the resulting substance has m. Bale. , 5 ° С and so on. Pl. 33-39,5 ° C.
