Description
Предлагаемый способ основан на образовании кристаллического продукта при кип чении аморфного осадка в присутствии аммоииевых солей, иапример, сульфата аммони .The proposed method is based on the formation of a crystalline product during the boiling of an amorphous precipitate in the presence of ammonium salts, and, for example, ammonium sulfate.
Процесс может быть выражен следующим уравнением:The process can be expressed by the following equation:
Al2(OH)6+(NH4)jS04 AU(OH)4S04+2NH3 + 2H20Al2 (OH) 6+ (NH4) jS04 AU (OH) 4S04 + 2NH3 + 2H20
Выдел ющийс аммиак может быть уловлен прокаливанием при 1200°С образовавщихс кристаллов основной соли алюмини .Released ammonia can be captured by calcining the resulting crystals of basic aluminum salt at 1200 ° C.
Реакци по приведенному уравнению вл етс специфической дл аморфного гидрата окиси алюмини . С кристаллическим гидратом реакци не проходит. .The reaction according to the above equation is specific to amorphous alumina hydrate. With crystalline hydrate, the reaction does not work. .
Описанный прием может быть использован дл получени окиси алюмини из алюминиевых квасцов.The described technique can be used to obtain alumina from aluminum alum.
Предметизобретени Subject matter
Способ превращени аморфного гидрата окиси алюмини в основную соль алюмини , отличающийс тем, что, с целью улучщени фильтруемости, аморфиый гидрат окиси алюмини кип т т в нейтральиом растворе аммониевых солей.A method of converting an amorphous alumina hydrate to a basic aluminum salt, characterized in that, in order to improve filterability, an amorphous alumina hydrate is boiled in a neutral solution of ammonium salts.
