Versuchsvorschrift

Further, Neftekhimiya, 16(1), 119—119, (1976) discloses a method in which 1,2-epoxy-5,9-cyclododecadiene is brought into contact with hydrogen in the presence of a palladium-carrying catalyst under a hydrogen pressure of 9.06 MPa (80 atmospheres) at a temperature of 140° C. By this method, 49.5% of epoxycyclododecane, 33.3% of cyclododecanol and 3.4% of cyclododecanone were obtained. In this method, the yields of cyclododecanol and cyclododecanone were unsatisfactory.
