Abstract
The invention relates to a process for the hydrogenation of phenyl acetylene in a styrene-containing medium with the aid of a supported nickel catalyst with a nickel content of 10-25 wt. %. This process is by preference used for the hydrogenation of phenyl acetylene in a styrene-containing medium which contains more that 30 wt. % of styrene.
