Description
Изобретение относитс к области получени галогенсодерхсащих соещшеннй графита преимущественно фторсодержащих, в частности ; соединений графита с трифторидом брома, которые могут быть использованы в качестве твердых фторирующих агентов дл синтеза фтороргани юских и неорганических соединений .The invention relates to the field of producing halogen-containing graphite compounds, preferably fluorine-containing, in particular; graphite compounds with bromine trifluoride, which can be used as solid fluorinating agents for the synthesis of organofluorine and inorganic compounds.
Известен способ получени соединени графита с трифторидом брома путем смачивани порошка графита с размером частиц менее 0,063 мм жидким трифторидом брома, вакуумировани смеси до давлени 10 мм рт.ст. и нагревани до 49-183°G. На синтез требуетс 44-48 ч, расход фторида брома составл ет 24 г на 1 г графита. В результате получиют соединение состава Cg BrFj, содержащего 24,7% фтора и разлагающегос при 179°С 1.A method is known for producing a graphite compound with bromine trifluoride by wetting graphite powder with a particle size of less than 0.063 mm with liquid bromine trifluoride, evacuating the mixture to a pressure of 10 mm Hg. and heating to 49-183 ° G. The synthesis requires 44-48 hours, the consumption of bromine fluoride is 24 grams per gram of graphite. As a result, a compound of composition Cg BrFj containing 24.7% fluorine and decomposing at 179 ° C 1 is obtained.
Основными недостатками способа вл ютс его болыца продолжительность и сложность, а также низкое содержание фтора в конечном продукте.The main disadvantages of the method are its large duration and complexity, as well as the low fluorine content in the final product.
Известен также другой способ соединени графита с трифторидом брома, согласно которому порошок графита обрабатывают жидким трифторидом брома при температуре от -40 до +20°С в течение 14-16 ч. На обработку 1 г графита расходуетс 40 г трифторида брома. В результате получают соединение состава CgjgBrFs,, содержащего 32,8% фтора, 27,0% брома и 40,2% углерода 2.Another method of combining graphite with bromine trifluoride is also known, according to which graphite powder is treated with liquid bromine trifluoride at a temperature of from -40 to + 20 ° C for 14-16 hours. 40 g of bromine is consumed for processing 1 g of graphite. The result is a compound of the composition CgjgBrFs, containing 32.8% fluorine, 27.0% bromine and 40.2% carbon 2.
Недостатки данного способа заключаютс в большой длительности и сложности процесса , использовании знaчитeльF oгo избытка, трифторвда брома, чем это требуетс по стехиометрии , невысоком содержании фтора в соединении.The disadvantages of this method are the long duration and complexity of the process, the use of a significant amount of F excess, trifluoride bromine, which is required for stoichiometry, a low fluorine content in the compound.
Целью изобретеш вл етс интенсификаци , удещевление и упрощение процесса, увеличение содержани фтора в соединении.The goal of the invention is to intensify, facilitate and simplify the process, increasing the fluorine content in the compound.
Это достигаетс тем, что порощок графита обрабатывают газообразным трифторидом брома пр}1 температуре .This is achieved in that the graphite powder is treated with bromine trifluoride gas} 1 temperature.
Отличительной особенностью способа вл етс использова ше газообразного трифторида брома и проведение процесса при указанныхA distinctive feature of the method is the use of bromine trifluoride gas and carrying out the process at specified
