The present invention relates to a method of regenerating a ruthenium catalyst suitable for hydrogenation, which comprises flushing the catalyst with inert gas in a regeneration step until the original activity or part of the original activity has been attained. The method is particularly useful for ruthenium catalysts which are used for the hydrogenation of aromatics.

Method of regenerating ruthenium catalysts suitable for hydrogenation

The present patent application describes a method of regenerating a ruthenium catalyst for the hydrogenation of benzene, which comprises flushing the catalyst with inert gas in a regeneration step until the original activity or part of the original activity has been attained.

Method of regenerating ruthenium catalysts for the hydrogenation of benzene

The present invention relates to a method of regenerating a ruthenium catalyst for the hydrogenation of phthalates, which comprises flushing the catalyst with inert gas in a regeneration step until the original activity or part of the original activity has been attained.

Method of regenerating ruthenium catalysts for the ring hydrogenation of phthalates

The present invention relates to a process for preparing 1,2-propanediol, in which a glycerol-containing stream, especially a stream obtained on the industrial scale in the production of biodiesel, is subjected to a low pressure hydrogenation.

Method for producing 1,2-propandiol by low-pressure hydrogenation of glycerine

The invention relates to a shell catalyst containing ruthenium as an active metal, alone or together with at least one other metal of the auxiliary group IB, VIIB or VIII of the periodical system of the elements (CAS version), and applied to a carrier containing silicon dioxide as a carrier material. The invention also relates to a method for producing said shell catalyst, and to a method for hydrogenating an organic compound containing hydrogenable groups, preferably for hydrogenating a carbocyclic aromatic group to form the corresponding carbocyclic aliphatic groups or for hydrogenating aldehydes to form the corresponding alcohols, using the inventive shell catalyst. The invention further relates to the use of the inventive shell catalyst for hydrogenating an organic compound containing hydrogenable groups, preferably for hydrogenating a carbocyclic aromatic group to form the corresponding carbocyclic aliphatic groups or for hydrogenating aldehydes to form the corresponding alcohols.

Catalyst and process for hydrogenating organic compounds comprising hydrogenatable groups

The present invention relates to a process for the preparation of 1,2-propanediol, in which a glycerol-containing stream, in particular a stream obtained on an industrial scale in the production of biodiesel, is subjected to a hydrogenation.

Process for the preparation of 1,2-propanediol

Process for preparing aminodihalophosphines, diaminohalophosphines, triaminophosphines, phosphorous ester diamides, aminophosphines, diaminophosphines, phosphorous ester amide halides and aminophosphine halides with elimination of an acid in the presence of an auxiliary base, wherein the auxiliary base

Method for the separation of acids from chemical reaction mixtures by means of ionic fluids

A process for removing acids from reaction mixtures using an auxiliary base, in which the auxiliary base: combines with the acid to form a salt which is liquid at temperatures at which the product of value does not significantly decompose during the removal of the liquid salt, and the salt of the auxiliary base with the product of value or the solution of the product of value in a suitable solvent forms two immiscible liquid phases.

The present invention relates to a process for preparing 5-alkoxy-substituted oxazoles, in particular for preparing 4-methyl-5-alkoxy-substituted oxazoles and also a process for preparing pyridoxine derivatives.
