Shaped bodies with good strength properties are prepared from pyrogenic metal oxide(s) by suspending the metal oxide(s) in a liquid, milling to activate the metal oxide particles, forming an activated homogenous suspension, coagulating the suspension, and forming shaped bodies therefrom.

Method for producing stable, high-purity molded bodies from pyrogenic metal oxides without the addition of binders

Yield and selectivity of olefin acetoxylation are improved through the use of successive catalyst zones of different reactivities, the successive zones contained in one or more reaction tubes arranged is parallel.

Process for the acetoxylation of olefins in the gas phase

Especially physically stable metal oxide catalyst supports are prepared by suspending a metal oxide in a continuous phase, activating by fine dispersion, coagulation to a viscoelastic mass, shaping, drying, and calcining. The catalyst support thus prepared may be treated with catalytic agents to produce supported catalysts for olefin oxidation.

Method for producing catalysts and their use for the gas phase oxidation of olefins

The invention relates to a method for carrying out CC-coupling reactions, in particular a Heck and Suzuki reaction, in the presence of supported palladium as the catalyst and a base in a monophase or multiphase solvent mixture. According to said method, palladium detaches itself from the support in a characteristic manner, is redeposited after the reaction and the quantity of palladium not deposited after the reaction is significantly lower than 5000 ppm, in relation to the palladium used.
