  • Method for continuously producing a product by way of at least two coupled-together chemical reactions
    Patent number: 11231727
    Abstract: A method for continuously producing a product (A1) by way of at least two coupled-together chemical reactions (C1, C2), wherein at least two input substances (E1, E2) are fed to a first chemical reaction (C1), wherein a plurality of intermediate substances (Z1, Z2) are produced from the input substances (E1, E2) by the first chemical reaction (C1), wherein at least one of the intermediate substances (Z2) is fed to a second chemical reaction (C2), wherein the at least one fed intermediate substance (Z2) is further processed by the second chemical reaction (C2), in particular using at least one further substance (W1, W2) in a second chemical reaction (C2) to form a plurality of output substances (A1, A2), that is to say to form the chemical product (A1) and at least one further output substance (A2), wherein the flow rates (Fi) of the fed substances (E1, E2, Z1, W1, W2, A2) that are fed to one of the reactions (C1, C2) are set by a respective actuating element (VE1, VE2, VW1, VW 2, VZ 2, VA1), wherein each of t

  • Process for monitoring and controlling nitrating processes with the aid of an online spectrometer
    Patent number: 7227147
    Abstract: A process for monitoring and/or controlling a nitrating process, having the following steps: measuring inline infrared spectra of nitric acid content in a reaction mixture stream downstream of the nitration reaction, preferably near-infrared spectra, evaluating the measured spectra by means of a computer-assisted, matrix-specific calibration model for the purpose of determining the content of nitric acid, transmitting the results of spectrometric examination to a process control system, inputting the results of spectrometric examination for the purpose of specifying the content of nitric acid in the acid phase into a regulator (224) for control of the metering (207,217) of nitric acid into a nitrating reactor.
