The present invention relates to a process for preparing alkanolamines and ethyleneamines in the liquid phase, by reacting ethylene glycol and/or monoethanolamine with ammonia in the presence of an amination catalyst which is obtained by reducing a catalyst precursor, wherein the preparation of the catalyst precursor comprises a step a) in which a catalyst precursor comprising one or more catalytically active components of Sn, Cu and Ni, and a step b) in which the catalyst precursor prepared in step a) is contacted with a soluble Re compound.

Method for the production of ethyleneamines

The invention relates to processes for preparing alkanolamines and ethyleneamines in the liquid phase, by reacting ethylene glycol and/or monoethanolamine with ammonia in the presence of an amination catalyst comprising one or more active metals selected from Sn and the elements of groups 8, 9, 10 and 11 of the Periodic Table of the Elements, wherein the amination catalyst is obtained by reductive calcination of a catalyst precursor. The catalyst precursor here is preferably prepared by contacting a conventional or catalytic support material with one or more soluble compounds of the active metals and optionally one or more soluble compounds of added catalyst elements. The present invention further relates to a process for preparing an amination catalyst comprising one or more active metals selected from Sn and the elements of groups 8, 9, 10 and 11 of the Periodic Table of the Elements, the amination catalyst being obtained by reductive calcination of a catalyst precursor, wherein the reactor in which the catalyst precursor is reductively calcined is connected to a denox plant, and to the use of a denox plant in the preparation of amination catalysts.

Method for producing ethyleneamines

The present invention relates to a process for hydrogenating nitriles with hydrogen in the presence of a ZrO-supported ruthenium catalyst.

Method for hydrogenating nitriles in the presence of a ruthenium catalyst carried on ZrO

The present invention relates to a catalyst for decomposition of nitrous oxide and also to its method of preparation and use.

Catalyst for decomposition of nitrous oxide

The present invention relates to a nitrous oxide decomposition catalyst, the preparation and use. The catalyst contains rhodium on a catalyst carrier. The carrier is obtained by mixing zirconium dioxide powder with a silicon compound as binder, to form a kneadable composition, homogenizing the composition, shaping the composition into shaped articles, drying and calcination, wherein the binder is selected from silicon compounds of general formulae (I) to (VI)(Hal)SiR&#x2003;&#x2003;(I)(Hal)Si(OR)&#x2003;&#x2003;(II)(Hal)Si(NRR)&#x2003;&#x2003;(III)RSi(OR)4-&#x2003;&#x2003;(IV)RSi(NRR)&#x2003;&#x2003;(V)(RO)Si(NRR)&#x2003;&#x2003;(VI)
