实验步骤: 100 kg of 8-cyclohexadecenone (odoriferously good quality: GC ratio of (E) and (Z) isomers was 2.5:1), 45 kg of acetone and 100 g of palladium on activated charcoal (Pd content: 5 wt. %) with 40% water content were placed in a stirred autoclave equipped with a gassing stirrer. The reaction mixture was hydrogenated for 12 hours at 35° to 40° C. and at 15 bar hydrogen pressure and then filtered. After removing the acetone 99.2 kg of cyclohexadecanone were obtained (GC content of cyclohexadecanone: >98%). The product thereby obtained was of a good perfumery quality. The perfumery quality could be improved still further by recrystallisation from methanol. equipped with a gassing stirrer filtered After removing the acetone 99.2 kg of cyclohexadecanone
