The invention relates to a continuously operating process for producing nitrobenzene, comprising the following steps: a) nitriding benzene in adiabatic conditions with sulfuric acid and nitric acid, using a stoichiometric excess of benzene in relation to the nitric acid; b) first separating a gaseous phase containing benzene and gaseous secondary components from the raw process product of the nitridation in a gas separator provided specifically for this purpose, then separating, in a downstream phase-separating apparatus, the resulting liquid phase, which is depleted in gaseous components and contains nitrobenzene and sulfuric acid, into a sulfuric acid phase and a nitrobenzene phase; and c) processing the nitrobenzene phase, obtaining nitrobenzene. The invention also relates to a production plant suitable for carrying out the claimed process.

A solid-supported Pd catalyst is suitable for C—C bond formation, e.g., via Suzuki-Miyaura and Mizoroki-Heck cross-coupling reactions, with a support that is reusable, cost-efficient, regioselective, and naturally available. Such catalysts may contain Pd nanoparticles on jute plant sticks (GS), i.e., Pd@GS, and may be formed by reducing, e.g., K.sub.2PdCl.sub.4 with NaBH.sub.4 in water, and then used this as a “dip catalyst.” The dip catalyst can catalyze Suzuki-Miyaura and Mizoroki-Heck cross coupling-reactions in water. The catalysts may have a homogeneous distribution of Pd nanoparticles with average dimensions, e.g., within a range of 7 to 10 nm on the solid support. Suzuki-Miyaura cross-coupling reactions may achieve conversions of, e.g., 97% with TOFs around 4692 h.sup.−1, Mizoroki-Heck reactions with conversions of, e.g., a 98% and TOFs of 237 h.sup.−1, while the same catalyst sample may be used for 7 consecutive cycles, i.e., without addition of any fresh catalyst.
