Abstract
Effect of metal complex on hydrogenation of o-chloronitrobenzene (o-CNB) ov
er poly-vinylpyrrolidone stabilized ruthenium colloid (PVP-Ru) has been stu
died in methanol media under 320 K and 4.0 MPa. The addition of Zn(II) comp
lexes of diamines to PVP-Ru catalyst system leads to significant increase i
n the activity of PVP-Ru, while the selectivity for o-chloroaniline (o-CAN)
maintained similar to 100%. Especially, rate enhancement more than 30 time
s that over neat PVP-Ru has been achieved in the presence of Zn(trien)Cl-2.
It was verified that the incorporation of Zn(II) complexes of multi-amines
changed the reaction kinetics. (C) 2001 Elsevier Science B.V. All rights r
