Synthesis of p-menthane were prepared via dipentene hy- drogenation,adopting the new automation control technology of total recycle hydrogenated in fixed bed and the modified catalyst of skeletal nickel. Catalyst skeletal nickel and Pd/C was researched on dipentene hydrogenation. The effect of conversion rate of dipentene and yield of p-menthane were conducted to examine the process of hydro genation by changing reaction temperature, reaction pressure and reaction time. The best parameters of catalytic reaction technique was determined through ...
