Versuchsvorschrift

Cardanol (500 g, 1.64 mol) was dissolved in isopropanol (2 L) and was hydrogenated in presence of 5% Pd/C (1.5 g) catalyst at 70° C. in a Parr autoclave under 600 psi hydrogen pressure. When no more hydrogen absorption was noticed, the hydrogenation was stopped. The reaction mixture was filtered to remove Pd/C. The solvent was evaporated to obtain crude product. Pure 3-pentadecylphenol was obtained after recrystallization from hexane. Yield 480 g, (95%), MP: 50-51° C.
