(54) СПОСОБ ПОЛУЧЕНИЯ ГИДРООКИСЕЙ РАССЕЯННЫХ ЭЛЕМЕНТОВ ПОДГРУППЫ ГАЛЛИЯ(54) METHOD FOR GETTING HYDROXIDES OF MULTIPLE ELEMENTS OF GALLIA SUBGROUP

1one

Изобретение относитс  к способам получени  гидроокисей рассе нных элементов подгруппы галли  и может быть использовано в технологии получени  соединений галли , инди  и талли .The invention relates to methods for producing hydroxides of scattered elements of the gallium subgroup and can be used in the technology for producing gallium, indium and thallium compounds.

Известен способ получени  гидроокиси галли , заключающийс  в автоклавной обработке металлического галли  водой при 200°С в течение 20 час с последующим охлаждением раствора и выделением из него гидроокиси галли .A method of producing gallium hydroxide is known, consisting in autoclaving the treatment of metallic gallium with water at 200 ° C for 20 hours, followed by cooling the solution and recovering gallium hydroxide from it.

Цель изобретени  - ускорение процесса.The purpose of the invention is to accelerate the process.

Это достигаетс  благодар  тому, что автоклавную обработку осуществл ют водными растворами кислот в присутствии окислител , например перекиси водорода.This is due to the fact that the autoclave treatment is carried out with aqueous solutions of acids in the presence of an oxidizing agent, for example hydrogen peroxide.

Пример. 20 г металлического инди , 50 мл 0,2 н. раствора сол ной кислоты и 5 млExample. 20 g of metallic indie, 50 ml 0.2 n. hydrochloric acid solution and 5 ml

30%-ноге раствора перекиси водорода помещают в автоклав и производ т автоклавную обработку в течение 2,5 час при 180°С. После охлаждени  и вскрыти  автоклава белые кристаллы гидроокиси инди  в количестве 19,8 г отдел ют от раствора. Выход конечного продукта близок к 99,1 %.A 30% hydrogen peroxide solution is placed in an autoclave and subjected to autoclave treatment for 2.5 hours at 180 ° C. After cooling and opening the autoclave, 19.8 g of white indium hydroxide crystals are separated from the solution. The yield of the final product is close to 99.1%.
