The invention relates to an adiabatic process for producing nitrobenzene by nitrating benzene with sulphuric acid mixtures and nitric acid mixtures using a stoichiometric excess of benzene and reusing non-reacted benzene, the content of the aliphatic organic compounds in the feed benzene being limited, by the targeted evacuation of aliphatic organic compounds to at least one step in the process, to a content of less than 1.5 mass-%, in relation to the total amount of feed benzene.
The invention relates to a continuous adiabatic process for producing nitrobenzene by nitrating benzene with sulphuric acid mixtures and nitric acid mixtures using a stoichiometric excess of benzene, the content of organic compounds in the sulphuric acid cycle being maintained, at least during the starting of the production system, at a level lower than 1.0 mass % in relation to the total mass of the sulphuric acid cycle. This is achieved, preferably, either after the end or prior to the start of the production cycle, by starting the circulation of the sulfuric acid cycle at a higher temperature in order to separate the organic substances contained in the sulphuric acid and comprising, preferably nitrobenzene and traces of benzene, dinitrobenzene and nitrophenol, in an evaporation device for concentrating the sulphuric acid.
The invention relates to a continuous method for producing nitrobenzene by nitrating benzene with sulphuric acid mixtures and nitric acid mixtures using a stoichiometric excess of benzene, the content of the aliphatic organic compounds in the feed benzene being maintained, during the starting of the production system, at a level lower than 1.5 mass % in relation to the total mass of the feed benzene. This is achieved, either when starting the production system, the feed benzene consisting of recycled and unreacted benzene (recycled benzene) and the benzene newly introduced into the reaction (fresh benzene) is mixed in appropriate amounts, according to the purity of both flows, or when starting, the unreacted benzene is completely withdrawn from the recycling, the feed benzene only being benzene newly introduced into the reaction.
