Procedure
From Example 9Ci above, 0.276 g (0.001 mole) of 5-cyclododecylidene pentanoic acid was dissolved in 30 ml of glacial acetic acid. Platinum oxide (0.027 g) was added and the mixture was hydrogenated on a sloping-manifold hydrogenation apparatus for 3 hr at room temperature. The resultant mixture was then filtered through Celite (diatomaceous earth). The solvent was removed in vacuo to yield 0.26 g (93.8%) of 5-cyclododecylpentanoic acid having the following physical characteristics:
