Abstract

In the current work, the process of 2,4-PD hydrogenolysis is studied in a combined effort of experiments and computer simulation, to understand the mechanism and factors controlling the C-C vs. C-O bond cleavage selectivity of this process. It is expected that the results from this study will be useful in control of the selectivity of sugar hydrogenolysis, as the bond cleavage mechanism in sugar hydrogenolysis is the same as in 2,4-pentanediol hydrogenolysis. In this capacity, the effects of reaction conditions, including temperature, base concentration, hydrogen pressure, catalyst amount and catalyst type, on the C-C vs. C-O bond cleavage selectivity of 2,4-pentanediol hydrogenolysis are investigated both experimentally and via simulation. The simulation study strengthens the experimental investigation in several aspects. It allows the process to be explored in a larger range of reaction conditions, the mechanism and factors controlling the selectivity to be understood at a deeper level, and the features of catalysts critical to improving the selectivity to be identified. However, the experimental data are useful in providing a baseline for the simulation results to be compared.
