catalytic and metal-containing compositions, processes for the preparation of a metal-containing composition and for the preparation of a catalytic composition, and use of a metal-containing composition

摘要

"METAL AND CATALYTIC COMPOSITION, PROCESSES FOR PREPARING A METAL CONTAINING COMPOSITION, AND PREPARING A CATALYTIC COMPOSITION, AND USING A METAL CONTAINING COMPOSITION". Metal-containing composition and its use in catalytic reactions, the metal-containing composition of which may be obtained by contacting a metal hydroxide salt with a solution comprising one or more pH-dependent anions selected from the group consisting of boron-containing anions, vanadium-containing anions, tungsten-containing anions, molybdenum-containing anions, iron-containing anions, niobium-containing anions, tantalum-containing anions, aluminum-containing anions, and pH-dependent gallium-containing anions.
