Description

Изобретение относитс  к способам получени  алюмината магни  А&„0.The invention relates to methods for producing magnesium aluminate A &

известен способ получени  алюмината магни  смешением солей алюмини  с растворами сульфата магни  и аммиака, отделением образовавшегос  осадка; промывкой его и прокаливанием р.,a method for producing magnesium aluminate is known by mixing aluminum salts with magnesium sulfate and ammonia solutions, separating the precipitate formed; rinsing and calcining it,

Существенным недостатком известного способа  вл етс  сложность получени  алюмината магни  за счет образовани  труд- нофильтруемого осадка.A significant disadvantage of the known method is the difficulty of producing magnesium aluminate due to the formation of a hardly filtered precipitate.

Целью изобретени   вл етс  упрощение процесса за счет получени  легкофильтруе мого кристаллического осадка.The aim of the invention is to simplify the process by producing a readily filterable crystalline precipitate.

Поставленна  цель достигаетс  тем, что в качестве соединени  алюмини  .используют гидроокись алюмини , а в качест ве щелочного агента - карбонат натри . Смешение компонентов Ьедут при рН 9,2-9,6 и температуре 65-8О°С. Полученый осадок фильтруют, промьлвают, сушат и прокаливают при 700-900 - C.This goal is achieved in that aluminum hydroxide is used as an aluminum compound, and sodium carbonate is used as an alkaline agent. The mixture of components is run at a pH of 9.2-9.6 and a temperature of 65-8 ° C. The precipitate obtained is filtered, washed, dried and calcined at 700-900 - C.

Процесс термического разложени  осадка происходит по реакции;,The process of thermal decomposition of the precipitate occurs by the reaction;

он 2СОз- -4Ае(it is 2CO3-4Ae (

2Mg-Ae O - -7H2O -i-CO2Mg-Ae O - -7H2O -i-CO

Присутствие СО и вод ных паров бла- гопри тно вли ет на процесс синтеза, снижает температуру синтеза.The presence of CO and water vapor has a positive effect on the synthesis process, reduces the temperature of synthesis.

Пример. Дл  получени  1ОО в.ч. порошка Л д-ДG Соберут 170в.ч./Wg-SO ТН раствор ют в 510 в.ч. воды и при перемешивании добавл ют 110 в.ч. AC(QH).Example. To obtain 1OO v.ch. Ld-DG powder. Collect 170 W.h./Wg-SO TH dissolved in 510 part by weight. 110 cf are added while stirring. AC (QH).

Суспензию подогревают до 70°С при непрерывном перемешивании и небольшими порци ми приливают вод ной раствор до ,5.The suspension is heated to 70 ° C with continuous stirring and the aqueous solution is poured in small portions to 5.

Образовавшийс  осадок гидрокарбона та магни  с гидроокисью алюмини  отфильтровывают , промывают, сушат и прокаливают в течении 1,5 ч при 8ОО С. Образовавшийс  тонкодисперсный порошок на 98,8% состоит из Mg-AE O.The resulting precipitate of hydrocarbon and magnesium with aluminum hydroxide is filtered, washed, dried and calcined for 1.5 hours at 8OO C. The fine powder formed is 98.8% Mg-AE O.
