Изобретение относитс  к способам получени  карбоната рубиди  и может быть использовано дл  получени  чистых соединений рубиди .The invention relates to methods for producing rubidium carbonate and can be used to obtain pure rubidium compounds.

Известен способ получени  карбоната рубиди , СОСТОЯП1ИЙ в том, что водные растворы перманганата рубиди  обрабатывают углеродсодержащими восстановител ми (щавелевой и муравьиной кислотами, этиловым спиртом). В результате реакции марганец осаждаетс  в форме двуокиси марганца. Рубидий остаетс  в растворе, который упаривают досуха, и осадок прокаливают до получени  карбоната рубиди . Однако такой способ имеет большие потери рубиди  с осадком двуокиси марганца и очень малую скорость фильтрации последнего .A known method for the preparation of rubidium carbonate, COMPOSITION in that aqueous solutions of rubidium permanganate are treated with carbon-containing reducing agents (oxalic and formic acids, ethyl alcohol). As a result of the reaction, manganese precipitates in the form of manganese dioxide. The rubidium remains in the solution, which is evaporated to dryness, and the precipitate is calcined to obtain rubidium carbonate. However, this method has a large loss of rubidium with manganese dioxide precipitate and a very low filtration rate of the latter.

С целью повышени  выхода продукта и ускорени  процесса фильтрации двуокиси марганца предлагаетс  реакционную смесь после введени  ш;авелевой кислоты дополнительно обрабатывать гидразипгидратом, вз тым в количестве 0,60-0,63 моль на 1 моль перманганата рубиди . Щавелева  кислота должна быть введена в количестве 1 моль па 1 моль пермапганата рубиди .In order to increase the product yield and speed up the manganese dioxide filtration process, it is proposed to further treat the hydrated mixture of 0.60-0.63 mol per 1 mol of rubidium permanganate after the introduction of brillian acid. Oxalic acid should be introduced in the amount of 1 mole of pas 1 mole of rubidium permapganate.

Пример. Приготавливают 6,5%-ный раствор нерманганата рубиди  и 9- 0%-ные растворы 1давелевой кислоты и гидразипгидрата. Example. Prepare a 6.5% solution of rubidium nermanganate and 9-0% solutions of 1-dodelic acid and hydrazipihydrate.

На нриготовление берут 15 кг RbMnO4, 9,6 кг Н2С204-2Н2О и 2,25-2,3 л 99,9-99,5%-го гидразингидрата . В раствор перманганата рубиди  вливают при перемешивании последовательно растворы ш,авелевой кислоты и гидразингидрата со скоростью 2 л/мин на каждые 100 л раствора перманганата рубиди . Процесс провод т при 80±5°С. После заливки растворов реакционную смесь перемешивают 20-30 мин и фильтруют. Осадок двуокиси марганца тотчас промывают на фильтре 75 л гор чей воды, растворы упаривают досуха, сухой остаток прокаливают до карбоната рубиди . Получают 84,5-84,7 кг продукта, не содержаш,его примеси марганца, и -6,4 кг двуокиси марганца (в пересчете на сухое вешество ) с содержанием рубиди  не более 0,04-0,05%.For the preparation, 15 kg of RbMnO4, 9.6 kg of H2S204-2H2O and 2.25-2.3 liters of 99.9-99.5% hydrazine hydrate are taken. In a solution of rubidium permanganate, with a stirring successively, solutions of w, avelic acid and hydrazine hydrate are poured at a rate of 2 liters per minute for every 100 liters of rubidium permanganate solution. The process is carried out at 80 ± 5 ° C. After pouring the solutions, the reaction mixture is stirred for 20-30 minutes and filtered. A precipitate of manganese dioxide is immediately washed on the filter with 75 liters of hot water, the solutions are evaporated to dryness, and the dry residue is calcined to rubidium carbonate. Get 84,5-84,7 kg of the product, not containing, its impurity manganese, and -6.4 kg of manganese dioxide (in terms of dry matter) with a rubidium content of not more than 0.04-0.05%.

Выход рубиди  в продукт 99,9%.The yield of rubidium in the product is 99.9%.
