Изобретение относитс к способам приготовлени водных растворов соединений рутени и может быть использовано дл нанесени рутенийсодержащих покрытий на металлы и сплавы.The invention relates to methods for preparing aqueous solutions of ruthenium compounds and can be used for applying ruthenium-containing coatings on metals and alloys.
Известно, что водные растворы окиси хлорида рутени , полученные растворением его в воде или ИС1, неустойчивы, легко гидролизуютс , коррозионноактивны.It is known that aqueous solutions of ruthenium chloride, obtained by dissolving it in water or EC1, are unstable, easily hydrolyzed, and corrosive.
С целью получени концентрированных (до 73 г/л в пересчете на металлический рутений), стабильных и некоррозионпоактивных растворов рутени , растворение оксихлорида рутени провод т в концентрированном аммиаке при 60- 90°С. Ири этом образуютс аммиачные комплексные соединени рутени .In order to obtain concentrated (up to 73 g / l in terms of metallic ruthenium), stable and non-corrosive solutions of ruthenium, the dissolution of ruthenium oxychloride is carried out in concentrated ammonia at 60-90 ° C. In this way, ammonium complex compounds of ruthenium are formed.
Проведение процесса в разбавленных растворах аммиака и при температурах, не включенных в предлагаемый интервал, ведет к замедлению реакции и снижению концентрации Carrying out the process in dilute ammonia solutions and at temperatures not included in the proposed interval leads to a slower response and lower concentrations
получаемых растворов. Рпстворы устойчивы при длительном сто нии на воздухе.the resulting solutions. The solutions are stable during long-term exposure to air.
Пример. К 8,5 г Ru(OH)Cl3 добавл ют 100 мл 25%-ного водного раствора аммиака и нагревают, перемешива , до 80°С и упаривают до 50 мл.Example. To 8.5 g of Ru (OH) Cl3, 100 ml of a 25% aqueous ammonia solution are added and heated, with stirring, to 80 ° C and evaporated to 50 ml.
Получают раствор фиолетового цвета с концентрацией 73 г/л (в пересчете на металлический рутений).A purple color solution is obtained with a concentration of 73 g / l (in terms of metallic ruthenium).
