    摘要： The invention provides a continuous adiabatic process for the preparation of nitrobenzene by nitrating benzene with mixtures of sulfuric and nitric acids using a stoichiometric excess of benzene, wherein the content of organic compounds in the circulating sulfuric acid, at least during the start-up period of the production plant, is always kept below 1.0 mass percent, based on the total mass of circulating sulfuric acid. This is preferably achieved by a procedure in which, either after the end or before the beginning of a production cycle, the circulating sulfuric acid is circulated at elevated temperature so that the organics contained in the sulfuric acid, preferably comprising nitrobenzene and traces of benzene, dinitrobenzene and nitrophenols, are separated off in the evaporation apparatus for concentrating the sulfuric acid.

    摘要： The present invention relates to A method for producing aromatic amines by the hydrogenation of aromatic nitro compounds. This method comprises: A) supplying aromatic nitro compounds and hydrogen to a reactor and contacting them with a hydrogenation catalyst; and B) stopping the supply of aromatic nitro compounds and hydrogen to the reactor. In addition, B) is carried out by: B1) stopping the supply of aromatic nitro compounds to the reactor such that any remaining aromatic nitro compounds present in the reactor and/or in parts of the installation that are fluidically connected to the reactor upstream react with the hydrogen that is still being supplied to the reactor, and B2) stopping the supply of hydrogen after a predetermined time interval and/or after the concentration of aromatic nitro compounds in the gas flow entering the reactor falls below a predetermined value.
