Abstract: 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.

Abstract: Disclosed are an electrolyte additive and a preparation method therefor, an electrolyte and a lithium ion battery. The preparation method for an electrolyte additive comprises: dissolving a picric acid in an organic solvent to obtain an additive solution, the organic solvent comprising at least one element of B, F and N; and performing crystallization from the additive solution, to precipitate an electrolyte additive. The electrolyte additive helps to make a polymer layer and an SEI film more rigid and stable, and helps to suppress the growth of lithium dendrites. The electrolyte added with the electrolyte additive can reduce the resistance of a lithium ion battery, and further improving the cycle performance of the lithium ion battery. The lithium ion battery provided in the present disclosure comprises the electrolyte added with the electrolyte additive, and therefore has a lower resistance and better cycle performance.

Abstract: The present invention relates to a novel nitration process of 2-chloro-4-fluorobenzoic acid to 2-chloro-4-fluoro-5-ni-trobenzoic acid, 2-chloro-4-f luoro-3-nitrobenzoic acid and 3,5-dinitro-2-chloro-4-fluorobenzoic acid; purifying the crude reaction product; and recovering 2-chloro-4-fluoro-5-nitrobenzoic acid in an essentially pure form, which can be used in the synthesis of the herbicide saflufenacil.
