Description

Известны способы очистки алюмини  от примесей путем обработки жидкого алюм.ини  хлористым алюминием с последующ-им разложением образовавшегос  субхлорида алюмини  на алюминий .и хлористый алюминий . Однако такие спсобы дороги и технологически сложны, так как хлористый алюминий гигроскопичен и легко гидролизуетс .Methods are known for cleaning aluminum from impurities by treating liquid aluminum aluminum oxide with aluminum chloride followed by decomposition of the aluminum subchloride formed into aluminum and aluminum chloride. However, such plants are expensive and technologically complex, since aluminum chloride is hygroscopic and easily hydrolyzed.

По предлагаемому способу исходный алюминий обрабатывают в расплавленном виде парообразным хлористым натрием в -вакууме, что упрощает и удешевл ет процесс раф-инировани  алюмини Способ оснОВан на равновесной реакцииAccording to the proposed method, the initial aluminum is treated in a molten form with vaporous sodium chloride in -vacuum, which simplifies and cheapens the process of aluminum refining. The method is based on an equilibrium reaction

и осуществл етс  в вакуумном аппарате, представл ющем собой колонку , выполненную из графита. Нижн   часть колонки  вл етс  испарителем хлористого натри , средн   - реакционной зоной, а верхн   - конденсатором .and is carried out in a vacuum apparatus, which is a column made of graphite. The bottom of the column is the sodium chloride evaporator, the middle is the reaction zone, and the top is the condenser.

Парообразный хлористый нагрий из испарител  попадает в реакционную зону, в которой находитс  жидкий алюминий; температура зоны равна 1000°. При этой температуре парообразный хлористый натрий взаимодействует с ж.идким алюминием с образованием паров хлористого алЮМ.ИНи  и натри , которые отвод тс  в верхнюю часть колонки- конденсатор , имеющий температуру пор дка 800°. В конденсаторе протекает реакци  между хлористым алюминием и натрием в сторону образовани  алюмини  и хлОристото натри . Очищенный от примесей жидкий алюминий собираетс  в конденсаторе. Наход щиес  в исходном алюминии примеси (железо, кремиий, медь, марганец и др.) хлорируютс  незначительно , ввиду чего не загр зн ют очищенный алюминий. При рафинировании исходного алюмини  чистотой 99,6% получаетс  металл высокой степени чистоты - 99,998%.Vaporous ferric chloride from the evaporator enters the reaction zone in which the liquid aluminum is located; zone temperature is 1000 °. At this temperature, the vaporous sodium chloride reacts with liquid aluminum to form the alumina and sodium chloride vapors, which are vented to the top of the column — a condenser having a temperature of about 800 °. In the condenser, a reaction takes place between aluminum chloride and sodium towards the formation of aluminum and sodium chlorine. Refined liquid aluminum is collected in a condenser. The impurities found in the original aluminum (iron, cremation, copper, manganese, etc.) are slightly chlorinated, which is why they do not contaminate the purified aluminum. When refining raw aluminum with a purity of 99.6%, a high-purity metal is obtained - 99.998%.
