Abstract
A process for separating off cycloalkenes having at least two double bonds from a reaction mixture in hydrocarbon solution formed during the metathesis of cycloalkamonoenes or cyclomonoene/cyclopolyene mixtures comprising the steps of treating the reaction mixture with zeolites in the liquid phase, absorbing the olefins having at least two double bonds present in the solution by the zeolite, separating off the laden zeolite, and obtaining the cycloalkadienes and cyclopolyenes by desorption.
