Abstract

In the process for hydrogenating butadiyne over a catalyst which comprises at least one platinum group metal on an inorganic metal oxide as a support, the hydrogenation is performed at a pressure in the range from 1 to 40 bar and a temperature in the range from 0 to 100° C., and from 0.05 to 5% by weight, based on the overall catalyst, of platinum group metal is present on the support.
