Selective hydrogenation of cyclododecatriene to cyclododecene

摘要

Process for preparing cyclododecene by selective gas-phase hydrogenation of at least one starting material selected from the group consisting of cyclododecatriene, cyclododecadiene and mixtures thereof, wherein the starting material present in the gas phase is hydrogenated in the presence of a catalyst in a fixed bed reactor and the Bodenstein number for the process is greater than 100.
