[54] THIOETHERIFICATION OF MERCAPTANS IN C4-HYDROCARBON MIXTURES
[57] Abstract: Abstract The invention relates to a process for the thioetherification of mercaptans with multiply unsaturated hydrocarbons, carried out in a reactor with addition of hydrogen using a heterogeneous catalyst and in the presence of 1-butene. It is an object of the invention to configure a process of this type in such a way that the value derived from the crude C4 stream used is increased. This object is achieved by the hydrogen being introduced into the reaction in such a way that the molar ratio of hydrogen to multiply unsaturated hydrocarbons is not more than one.
