Steps:

3 PREPARA TION OF PARTI ALL Y HYDROGENA TED FARNESENE IN A CONTINUOUS FIXED BED REACTOR SYSTEM.
β-farnesene was pre-treated with alumina, then slurried with palladium catalyst, and then pumped into a one gallon batch reactor. The reactor was vented and purged three times with 50 psig of nitrogen. Hydrogen was flowed into the reactor at 5 slpm (up to max pressure of 100 psig). Agitation was started while heating the reactor wall to 60°C. The reaction temperature was allowed to rise to 80°C and then cooling water was used to hold the temperature at 80°C until 1 .2 equivalents of hydrogen were added. The temperature was then allowed to increase to 120°C. Cumulative hydrogen uptake was monitored using a hydrogen mass flow meter, totalizer and refractive index. After 1 .5 equivalents of hydrogen were added, the reactor was heated to the second stage temperature of 260°C. After 3 molar equivalents of H₂ were consumed, hydrogen flow was stopped and excess H₂ was vented. Agitation was reduced and the reactor cooled to at least 50°C. The reactor was purged twice with 20 psig of nitrogen during the cool down. The product was then separated from the catalyst by diatomaceous earth filtration and the reaction product analyzed by GC-FID yielding the following results:
