Description
Известно, что при нагревании растворов бисульфита или бисульфита и сульфита аммони под давлением получаетс элементарна сера и сульфат , например, по реакции:It is known that by heating solutions of bisulfite or bisulfite and ammonium sulfite under pressure, elemental sulfur and sulfate are obtained, for example, by the reaction:
2NH4 HSOg + CNHJ, 30з 2(NHJ2 S04H-S+H2O.2NH4 HSOg + CNHJ, 303 2 (NHJ2 S04H-S + H2O.
Применение этого способа, особенно разложение раствора бисульфита , затруднено тем, что реакци протекает при довольно высокой температуре и с большой скоростью (взрывоподобно).The application of this method, especially the decomposition of the bisulfite solution, is complicated by the fact that the reaction proceeds at a rather high temperature and at a high speed (explosion-like).
Также известно, что прибавка к раствору бисульфита некоторых веществ, например, серы, селена, тиосульфата, политионата и т. д. значительно ускор ет процесс и позвол ет проводить реакцию при более низкой температуре как под давлением, так и в открытом сосуде.It is also known that the addition of certain substances to the bisulfite solution, for example, sulfur, selenium, thiosulfate, polythionate, etc., significantly speeds up the process and allows the reaction to take place at a lower temperature both under pressure and in an open vessel.
Предлагаемый, согласно насто щему изобретению, способ получени серы и сульфита аммони из растворов сульфата и бисульфата аммони , которые могут быть получены или поглощением SOg раствором аммиака из отход щих газов медеплавильных печей и контактных сернокислотных заводов или каким-либо другим известным методом, позвол ет без значительного усложнени установки вести процесс разложени упом нутых растворов совершенно спокойно при достаточной скорости реакции.The proposed method of producing sulfur and ammonium sulfite from ammonium sulfate and ammonium sulfate solutions, which can be obtained either by absorbing SOg by ammonia solution from the exhaust gases of copper-smelting furnaces and contact sulfuric acid plants or by any other known method, allows considerable complication of the installation to carry out the process of decomposition of the said solutions quite calmly with a sufficient reaction rate.
Автор нашел, что разложение нейтральных растворов сульфита даже при высокой температуре идет совершенно спокойно с измеримой скоростью . Элементарна сера при этом или совсем не выдел етс из раствора или в очень небольшом количестве образуетс в первый момент реакции и при дальнейшем нагревании снова переходит в раствор. Раствор после проведени реакции приобретает сильно щелочной характер и содержит в себе тиосульфат, нолитионат, сульфат и другие соединени серы. Например , если нагревание раствора сульфита вести при те.мпературе 350°, то через короткий промежуток времени получаетс желтый раствор, в которо.м элементарна сера отсутствует . При разбавлении такого раствора водой в результате гидролиза из него выдел етс очень небольшое количество серы в коллоидальной форме.The author found that the decomposition of neutral sulfite solutions, even at high temperatures, proceeds quite calmly at a measurable rate. At the same time, elemental sulfur is either not released from the solution at all or in a very small amount is formed at the first moment of the reaction and with further heating it goes back into the solution. The solution after the reaction takes on a strongly alkaline character and contains thiosulfate, nitrite, sulfate and other sulfur compounds. For example, if the heating of the sulfite solution is carried out at a temperature of 350 °, after a short period of time, a yellow solution is obtained, in which elemental sulfur is absent. When such a solution is diluted with water as a result of hydrolysis, a very small amount of sulfur in the colloidal form is released from it.
Полученный нри разложении сульфита щелочной раствор, содержащий сульфат, тиосульфат, политионат и другие соединени серы, которые приThe alkaline solution obtained by decomposing sulfite is an alkaline solution containing sulfate, thiosulfate, polythionate and other sulfur compounds, which
