Abstract

Abstract:

A series of amorphous Ni-Mo-B catalyst was prepared by KBH₄ reduction for liquid phase dinitrotoluene(DNT) hydrogenation. The results showed that Ni-B catalyst exhibited high activity and selectivity in liquid phase hydrogenation of DNT to diaminotoluene(TDA), the activity of Ni-B catalyst has been enhanced obviously by introduction of Mo, and the selectivity of TDA was 100% when the molar fraction of Mo was smaller and equal to 6%. The characterizations of XRD, DSC, TEM, XPS, ICP and H₂-TPD showed that the addition of Mo could enhance the extent of long-range disorder, reduce the particle diameter from 60 nm to 15 nm, weaken the strength of Ni-H bond, improve the thermal stability and antioxidation, which resulted in the increasing activity of Ni-B. when the molar fraction of Mo was 6%, the conversion of DNT and the selectivity of TDA reached 99.8% and 100%, respectively.
