| abstract | 1,232,424. Hydrogenating cyclododecatrienes. COLUMBIAN CARBON CO. 12 July, 1968, No. 33485/68. Heading C5E. A process of hydrogenating a cyclododecatriene with gaseous hydrogen comprises a first step of maintaining a reaction temperature below 160‹ C. until a quantity of hydrogen has been reacted equivalent to 25-62% of that theoretically necessary to saturate the cyclododecatriene and a second step of reacting additional hydrogen at an increased temperature of up to 300‹ C. until the desired level of hydrogenation has been reached. The cyclododecatriene may be unsubstituted or ring-substituted by C 1 -C 3 alkyl groups or halogen. A hydrogenation catalyst such as palladium supported or activated carbon may be used. Example 2 describes the hydrogenation of cyclododecatriene-1,5,9, wherein the increased reaction temperature is maintained until 3 moles of H 2 per mole cyclododecatriene have reacted to give cyclododecane. Examples 7 to 11 describe the preparation of cyclododecene by maintaining the increased reaction temperature until a total of 2 moles of H 2 per mole of cyclododecatriene-1,5,9 have reacted. The process of the invention minimizes the formation of aromatic products. |
