Description
Изобретение относится к способам получения фосфора и может быть использовано в промышленности для получении окислов фосфора и фосфорной кислоты.The invention relates to methods for producing phosphorus and can be used in industry for the production of oxides of phosphorus and phosphoric acid.
Пятиокись фосфора находит применение как осушитель газов и жидкостей, а также для получения фосфорной кислоты. Кроме того, пятиокись фосфора используется в реакциях дегидратации и конденсации.Phosphorus pentoxide is used as a desiccant for gases and liquids, as well as for the production of phosphoric acid. In addition, phosphorus pentoxide is used in dehydration and condensation reactions.
Известны способы получения окислов фосфора взаимодействием фосфатов кальция в вакууме при повышенной температуре в присутствии неорганических соединений (феррофосфора, диоксида титана и окси хрома) [Л.Х. Винокуров, M.P. Коневский, А.П. Ретюнский, И.И. Риф, Ю.; Вильк, И.С. Буров и А.Л. Моссе. Способ получения окислов фосфора. А.с. №523868. Опубликовано 05.08.1976. Бюл. №29. от 26.10.76, М. Кл. C01 25/12; В.В. Печковский, Е.Д. Дзюба, М.Т. Соколов и В.В. Шепелева. Способ получения оксидов фосфора А.С. №1279957, C01B 25/12 30.12.86. Бюл. №48].Known methods for producing phosphorus oxides by the interaction of calcium phosphates in vacuum at elevated temperature in the presence of inorganic compounds (ferrophosphorus, titanium dioxide and hydroxy chromium) [L.Kh. Vinokurov, M.P. Konevsky, A.P. Retyunsky, I.I. Reef, U .; Wilk, I.S. Burov and A.L. Mosse. A method of producing phosphorus oxides. A.S. No. 523868. Posted on 08/05/1976. Bull. No. 29. from 10.26.76, M. Cl. C01 25/12; V.V. Pechkovsky, E.D. Dziuba, M.T. Sokolov and V.V. Shepeleva. The method of producing phosphorus oxides A.S. No. 1279957, C01B 25/12 12/30/86. Bull. No. 48].
Недостатком указанных способов является накопление в системе неорганических соединений и загрязненность окислов фосфора.The disadvantage of these methods is the accumulation of inorganic compounds in the system and the contamination of phosphorus oxides.
Наиболее близким способом того же назначения по совокупности признаков является способ получения пятиокиси фосфора путем окисления фосфора воздухом в процессе восстановления фосфора в смеси с углем и кварцем в пламенной печи при температуре 1200-1600°C, развиваемой за счет сгорания образующихся фосфора и окиси углерода [Н. Ruter, Е Cherdcon, G. Bayer, Пат. ФРГ // 50958, 1964].The closest way to the same purpose for the combination of features is a method for producing phosphorus pentoxide by oxidizing phosphorus with air in the process of reducing phosphorus in a mixture with coal and quartz in a flame furnace at a temperature of 1200-1600 ° C, developed by combustion of the resulting phosphorus and carbon monoxide [N . Ruter, E Cherdcon, G. Bayer, Pat. Germany // 50958, 1964].
Недостатки указанного способа: использование угля и кварца, выбросы в атмосферу парникового газа - диоксида углерода.The disadvantages of this method: the use of coal and quartz, emissions of greenhouse gas - carbon dioxide.
Задача заявляемого изобретения - получение чистого пятиокиси фосфора сжиганием фосфора.The task of the invention is to obtain pure phosphorus pentoxide by burning phosphorus.
Технический результат - полнота переработки фосфора.EFFECT: completeness of phosphorus processing.
Способ получения пятиокиси фосфора, отличающийся тем, что сгорание фосфора в автоклаве происходит при температуре 50-60°C путем подачи кислорода под давлением 0,06-0,07 МПа с последующим выделением продукта из газовой фазы охлаждением автоклава.A method of producing phosphorus pentoxide, characterized in that the combustion of phosphorus in the autoclave occurs at a temperature of 50-60 ° C by supplying oxygen at a pressure of 0.06-0.07 MPa, followed by separation of the product from the gas phase by cooling the autoclave.
Данный способ включает сгорание фосфора в автоклаве путем подачи кислорода под давлением в зависимости от количества фосфора, с последующим выделением продукта из газовой фазы охлаждением автоклава.This method involves the combustion of phosphorus in an autoclave by supplying oxygen under pressure depending on the amount of phosphorus, followed by separation of the product from the gas phase by cooling the autoclave.
Способ осуществляется в автоклаве (рис. 1), где 1 - корпус, 2 - манометр, 3 - вентиль, 4 - крышка, 5 - холодильник.The method is carried out in an autoclave (Fig. 1), where 1 is the body, 2 is the pressure gauge, 3 is the valve, 4 is the lid, 5 is the refrigerator.
Процесс осуществляется в автоклаве объемом 2 литра, куда вводят фосфор и нагревают до температуры 50-60°C при открытом вентиле для испарения влаги и воспламенения фосфора, после чего в автоклаве поддерживают давление кислорода 0,06-0,07 МПа путем подачи его из баллона.The process is carried out in a 2 liter autoclave, where phosphorus is introduced and heated to a temperature of 50-60 ° C with an open valve to evaporate moisture and ignite phosphorus, after which an oxygen pressure of 0.06-0.07 MPa is maintained in the autoclave by supplying it from a cylinder .
После окончании реакции автоклав охлаждается водой, при этом пятиокись фосфора конденсируется.After the reaction, the autoclave is cooled by water, while the phosphorus pentoxide condenses.
Преимуществами данного способа являются: полнота переработки фосфора; процесс протекает в автоклаве, что предотвращает попадание ядовитых соединений в окружающую среду; полученный продукт можно использовать как осушитель газов и жидкостей.The advantages of this method are: the completeness of the processing of phosphorus; the process takes place in an autoclave, which prevents the ingress of toxic compounds into the environment; the resulting product can be used as a desiccant for gases and liquids.
