What is the role of hydrogen pressure in the selective conversion of furfural to cyclopentanone and cyclopentanol?

Label:chem

Topic
Hydrogen pressure is a critical reaction parameter that affects the hydrogenation and rearrangement steps in the conversion of furfural.
Answer
Hydrogen pressure significantly impacts the conversion and selectivity. At 4 MPa H₂, complete conversion of furfural was achieved with 53.3% selectivity to CPO. Increasing the pressure to 5 MPa H₂ promoted further hydrogenation of CPO to CPL, increasing its selectivity from 16.3% to 18.2%.
