Claims17
-15. (canceled)
A catalyst for condensing alcohols, which comprises support material in contact with copper as promoter, wherein
- a) the support material comprises hydrotalcite-like compounds,
- b) the proportion of copper promoter is in the range of from 0.05 to 5.0% by weight,
- c) the support material has an Mg/Al ratio in the range of from 90/10 to 70/30, where the ratio is based on the weight of the respective oxides, wherein the catalyst may optionally comprise at least one further promoter element from the group consisting of Pt, Rh, Ru, Pd, Co, Ni, Pd, Cu, Ag and Au and the content of further promoter is in the range 0.01 to 2% by weight, with the proviso that the amount of copper promoter is greater than the amount of further promoter.
