Description

II

Изобретение от1носитс  к приготовлению алюминатов цинка и кадми . Алюминаты цинка и кадми  наход т практическое применение , например, в качестве катализаторов при синтезе винилацетата.The invention relates to the preparation of zinc and cadmium aluminates. Zinc and cadmium aluminates find practical application, for example, as catalysts in the synthesis of vinyl acetate.

Известен способ получени  алюминатов циика и кадми  взаимодействием водного раствора NH4C1, содержащего растворенную ZnO с - АЬОз марки А-2.A known method for producing aluminate and cadmium is by reacting an aqueous solution of NH4C1 containing dissolved ZnO with - AO3 grade A-2.

Однако в известном способе образуютс  или практически непористые модификации алюминатов Zn и Cd или только поверхностные соединени .However, in the known method, either practically non-porous modifications of aluminates Zn and Cd or only surface compounds are formed.

Цель изобретени  - повысить качество продукта.The purpose of the invention is to improve the quality of the product.

Достигаетс  это тем, что используют аммиа ,каты циика и кадми  и активную ок1ись алюмини  марки А-1, процесс ведут ири концентрации ионов цинка и кадми  от 0,1 до 0,01 ммоль/мл.This is achieved by using ammonia, cathium and cadmium and active aluminum of grade A-1, the process is carried out by a concentration of zinc ions and cadmium from 0.1 to 0.01 mmol / ml.

Пример. Павески образцов промышленной активной окиси алюмини  (фракци  0,2- 0,4 мм) помещают в стекл нный сосуд и заливают раствором аммиакатов Zn или Cd. Соотношение : 500, концентрации ионов Zn и Cd при этом равны 0,1 ммоль/мл, а концентрации избыточного, сверх необходимого дл  образовани  иона Zn ()4 аммиака 0,350 ммоль1мл и дл  образовани  иона Cd{NH3) -t 0,750 ммоль/мл;fiH 10,4 дл  растворов Zn, 11,4 дл  растворов Cd. При температуре контактного раствора 20°С через 10 суток получают продукты следующего состава: ZnO : : 3,6, CdO : : 2,5, измен -  услав1и  проведени  апыта, иЗМен ют состав образующихс  высокопористых полиалюминиевых соединений Zn и Cd дл  Zn: от ZnO : А12Оз 1 : 5,8 до ZnO : А12Оз 1 : 3,0 и дл  Cd: от CdO : А12Оз 1 : 4,0 до 1 : 1,6.Example. Paveski samples of industrial active alumina (fraction 0.2-0.4 mm) are placed in a glass vessel and poured over with a solution of ammonia Zn or Cd. Ratio: 500, the concentrations of Zn and Cd ions in this case are 0.1 mmol / ml, and the concentration of excess ammonia is above the ammonia required for the formation of the Zn () 4 ion 0.350 mmol1 ml and 0.750 mmol / ml for the formation of the Cd ion (NH3); fiH 10.4 for Zn solutions, 11.4 for Cd solutions. At a temperature of the contact solution of 20 ° C, after 10 days, products of the following composition are obtained: ZnO:: 3.6, CdO:: 2.5, change - carry out the test, and the composition of the highly porous polyaluminium compounds Zn and Cd for Zn is changed: from ZnO : A12Oz 1: 5.8 to ZnO: A12Oz 1: 3.0 and for Cd: CdO: A12Oz 1: 4.0 to 1: 1.6.

С изменением состава измен ют соответственно и пористую структуру образующихс  продуктов. Гидроалюмииаты Zn и Cd, полученные предлагаемым способом, обладают регулируемой пористой структурой, большой удельной поверхностью (пор дка сотен ), каркасным строением остова, что позвол ет использовать их в качестве поверхностно-актиеных веществ: ионитов, адсорбентов и катализаторов .With a change in the composition, the porous structure of the resulting products is also changed accordingly. Zn and Cd hydroalumyates, obtained by the proposed method, have an adjustable porous structure, a large specific surface (about hundreds), and a skeleton skeleton structure, which makes it possible to use them as surface active substances: ion exchangers, adsorbents and catalysts.

Способ получени  алюминатов цинка и кадми  Путем смвШени  соединений цин1ка :и кадми  с окисью алюмини , отличающийс  тем, что, с целью повышени  качества продукта , используют аммиакаты цинка и кадми  и окись алюмини  1ма;рки А-. процесс ведут прн концентрации ионов шгнка и кадми  от 0,1 до 0,01 ммоль/мл.The method of producing zinc aluminates and cadmium. By combining zinc and: cadmium compounds with alumina, characterized in that, in order to improve the quality of the product, zinc and cadmium ammine and mMA are used. the process is carried out by the concentration of lgc ions and cadmium from 0.1 to 0.01 mmol / ml.
