A process for producing a coated transition metal oxide involves subjecting a transition metal oxide and a pyrogenically produced lithium titanate and/or pyrogenically produced lithium aluminate to dry mixing. A coated transition metal oxide is obtainable by this process; and cathode for a lithium ion battery and a lithium ion battery containing such coated particles is useful.

Transition metal oxide particles encapsulated in nanostructured lithium titanate or lithium aluminate, and the use thereof in lithium ion batteries

The present invention relates to a process for preparing a pulverulent, porous crystalline metal silicate, comprising the following steps:

Production of pulverulent, porous crystalline metal silicates by means of flame spray pyrolysis

In a process for the epoxidation of an olefin with hydrogen peroxide in the presence of a solvent, where a mixture comprising olefin, an aqueous hydrogen peroxide solution and a solvent is continuously passed through a fixed bed of an epoxidation catalyst comprising a titanium zeolite, addition of a chelating agent to the aqueous hydrogen peroxide solution before mixing it with solvent reduces or prevents formation of deposits on the catalyst and blocking of orifices of a liquid distributor.

Process for the epoxidation of an olefin

In a process for the epoxidation of an olefin, where a mixture comprising olefin, hydrogen peroxide, water and methanol with a weight ratio of water to methanol of less than 1 is passed through a catalyst fixed bed comprising a shaped titanium silicalite catalyst, catalyst breakage is reduced by conditioning the dry catalyst with at least one conditioning liquid comprising water and from 25 to 45% by weight methanol.
