Abstract

Chlorine and potassium are introduced during the preparation of Mo−Ni and Cr−Ni complex compounds by using nickel chloride and potassium molybdate or dichromate as starting materials. The resulting compounds are isomorphous with a series of complexes prepared with nickel nitrate and ammonium heptamolybdate or dichromate, previously described. The influence of the presence of chlorine and of potassium on the properties of the catalysts obtained by reduction of these compounds by hydrogen is investigated. Potassium-containing catalysts show a behavior similar to copper based catalysts.

Abstract

Хлор и калий использовали в ходе приготовления комплексных соединений Mo−Ni и Cr−Ni, исходя из хлористого никеля и молибдата или бихромата калия в качестве исходных соединений. Продукты изоморфны, в противоположность серии комплексных соединений, приготовленных из нитрата никеля и гептамолибдата аммония и оплсанных ранее. Исследовано влияние присутствия хлора или калия на свойства катализаторов, полыченных восстановлением этих соединений водородом. Катализаторы, содержащие калий, ведут себя также как и катализаторы на основе меди.
