摘要：The title compound, C20H32O2, has been isolated from hydrogenated rosin. There are two independent molecules in the asymmetric unit. In each molecule, the cyclohexane ring assumes a chair conformation, while the two cyclohexene rings adopt half-chair and envelope conformations. Intermolecular O-H center dot center dot center dot O hydrogen bonding between carboxyl groups links pairs of independent molecules into dimers.
