H. Bonnemann et al., SUPPORTED PT-COLLOID CATALYSTS FOR THE SELECTIVE HYDROGENATION OF 3,4-DICHLORONITROBENZENE, New journal of chemistry, 22(7), 1998, pp. 713-717
Pre-prepared Pt hydrosols stabilized by surfactants may be used as pre
cursors for heterogeneous hydrogenation catalysts active in the select
ive high-pressure transformation of 3,4-dichloronitrobenzene to the co
rresponding aniline. The catalytic performance of the new systems was
evaluated in batchwise and continuous tests and the results are compar
ed to conventional Pt/C systems.
