Abstract

Изобретение относится к неорганической химии, а именно к способу получения металлического алюминия. Сущность изобретения: в емкость с глиноземом (Al2O3) при комнатной температуре вливается жидкий бром (Br). Раствор нагревается до 70°C, происходит самостоятельная экзотермическая реакция замещения. По реакции: 2Al2O3+6Br2=4AlBr3+3O2+Q. Из емкости удаляется остаточный кислород введением газообразного аргона. Бромид алюминия (AlBr3 t плавления=97,5°C) нагревается до 115°C. Полученный расплав подвергается электролизу: 2AlBr3+e-=2Al+3Br2. Катодом является алюминиевая решетка, анодом является платиновая решетка. Испаряющийся бром конденсируется, далее возвращается в производственный цикл. На катоде алюминий восстанавливается и оседает на катодной решетке. Катодная решетка с восстановленными алюминиевыми "наростами" подвергатеся плавке и формовой отливке.The invention relates to inorganic chemistry, and in particular to a method for producing metallic aluminum. The essence of the invention: liquid bromine (Br) is poured into a container with alumina (Al2O3) at room temperature. The solution is heated to 70 ° C, an independent exothermic substitution reaction occurs. According to the reaction: 2Al2O3 + 6Br2 = 4AlBr3 + 3O2 + Q. Residual oxygen is removed from the vessel by introducing gaseous argon. Aluminum bromide (AlBr3 melting point = 97.5 ° C) is heated to 115 ° C. The resulting melt is subjected to electrolysis: 2AlBr3 + e- = 2Al + 3Br2. The cathode is an aluminum grating, the anode is a platinum grating. The evaporated bromine is condensed and then returned to the production cycle. At the cathode, aluminum is reduced and deposited on the cathode lattice. The cathode grid with recovered aluminum "build-ups" is melted and molded.
