Abstract
The invention relates to a method for the thioetherification of mercaptanes with polyunsaturated hydrocarbons, carried out in a reactor with the addition of hydrogen, using a heterogenic catalyst and in the presence of 1-butene. The aim of the invention is to develop such a method to the extent that the creation of value from the Craw material stream is increased. Said aim is achieved in that the hydrogen is added to the reaction in such a manner that the molar ratio of hydrogen to polyunsaturated hydrocarbons is no more than one.
