Abstract: Catalytic process for preparing an α,β-ethylenically unsaturated carboxylic acid salt, wherein an alkene and carbon dioxide are reacted in the presence of a carboxylation catalyst and in the presence of a specific aryloxide to obtain the α,β-ethylenically unsaturated carboxylic acid salt, the carboxylation catalyst being a transition metal complex. The process allows for efficient preparation of α,β-ethylenically unsaturated carboxylic acid derivatives from CO2 and an alkene.

Abstract: The present invention relates to a process for preparing ethanolamines and/or ethyleneamines in the gas phase by reacting ethylene glycol with ammonia in the presence of an amination catalyst. It is a characteristic feature of the process that the amination catalyst is prepared by reducing a calcined catalyst precursor comprising an active composition, where the active composition comprises one or more active metals selected from the group consisting of the elements of groups 8, 9, 10 and 11 of the Periodic Table of the Elements and optionally one or more added catalyst elements selected group consisting of the metals and semimetals of groups 3 to 7 and 12 to 17, the element P and the rare earth elements. It is a further characteristic feature of the process that a catalyst precursor having low basicity is used, the low basicity being achieved in that a) the catalyst precursor is prepared by coprecipitation and the active composition additionally comprises one or more basic elements selected from the group consisting of the alkali metals and alkaline earth metals; or b) the catalyst precursor, as well as the active composition, additionally comprises a support material and is prepared by impregnating the support material or precipitative application onto the support material and the support material comprises one or more basic elements selected from the group consisting of the alkali metals, Be, Ca, Ba and Sr or one or more minerals selected from the group consisting of hydrotalcite, chrysotile and sepiolite; or c) the catalyst precursor, as well as the active composition, additionally comprises a support material and is prepared by impregnating the support material or precipitative application onto the support material and the active composition of the catalyst support comprises one or more basic elements selected from the group consisting of the alkali metals and the alkaline earth metals; or d) the catalyst precursor is calcined at temperatures of 600° C. or more; or e) the catalyst precursor is prepared by a combination of variants a) and d) or by a combination of variants b) and d) or by a combination of variants c) and d).
