Abstract

В способе получения катализаторов оболочкового типа из палладия и палладия/золота для получения винилацетата усовершенствование заключается в использовании соли бария для осаждения водонерастворимых соединений палладия и, возможно, золота на носитель до восстановления с помощью восстанавливающего агента. Добавка в виде соли бария также может быть введена в катализатор после восстановления с целью уменьшения стремления катализатора к потере активности при использовании.
