摘要： The invention relates to a method for producing aromatic amines by hydrogenating nitro-aromatic compounds in the presence of catalysts consisting in forming, in a reactor, a fluid amine-containing reaction mixture from which the catalysts are separated. After the separation of the catalysts, the inventive method consists in measuring the absorption of UV/VIS radiation by said reaction mixture in order to determine the concentration of nitro and nitroso compounds therein.

摘要： The invention relates to a method for producing amines by catalytically hydrogenating nitroaromatics and then separating the catalysts from the reaction mixture containing at least one aromatic amine and water. According to the inventive method, the catalysts are separated by means of membrane filtration which is carried out at a pressure of 5 to 50 bar on the side of the suspension, a difference in pressure between the side of the suspension and the side of the permeate of at least 0.3 bar, and a flow rate of 1 to 6 m/s on the side of the suspension.

摘要： The invention relates to a method for converting aromatic nitro compounds into the corresponding amines in the presence of hydrogenation catalysts. Said method is characterized in that hydrogenation catalysts are used in which nickel and platinum are provided on a carrier in the form of an alloy, the atomic ratio between nickel and platinum in said alloy ranging between 30:70 and 70:30.

摘要： The invention relates to a method for producing polyisocyanates by reacting primary amines with phosgene, comprising the following steps: a) mixing the amine with the phosgene; b) reacting the amine with the phosgene in a reactor, inside of which the mixture stays for a period of time and, optionally; c) transferring the discharge from the reactor from step b) into a distillation column. The invention is characterized in that the reactor cited in step b) is provided in the form of a tubular reactor.
