摘要： The invention relates to a method for the production of amines by hydrogenating the corresponding nitroaromates in a vertical reactor whose length is greater than its diameter. Said reactor has a jet nozzle directed downward and arranged in the top area of the reactor. The reaction mixture and optionally part of the educts are fed through said jet nozzle. The reactor also comprises an outlet at any given location of the reactor through which the reaction mixture is once again fed into an external circuit by means of a conveying element of the jet nozzle and the flow is reversed in the bottom area of the reactor. The invention is characterized in that part of the educts used hydrogen and/or nitroaromates are proportioned into the liquid phase of the reactor in such a way that said educts rise upward in the liquid phase.

摘要： The invention relates to a method for continually producing 1,3-dioxolan-2-ones such as ethylene carbonate or propylene carbonate by reacting a corresponding oxirane with carbon dioxide in liquid phase in the presence of a catalyst. The reaction is carried out in a two-part reactor. In the first part of the reactor, the reaction is carried out with back-mixing until a conversion rate of oxirane II of at least 80 % has been reached. In the second part, the reaction is completed under conditions without back-mixing, the carbon dioxide being guided to the oxirane II in a counterflow throughout the reactor.

摘要： The invention relates to a reactor (1) for gas/liquid or gas/liquid/solid reactions comprising a vertical longitudinal axis, a feed inlet (2) for a liquid or liquid/solid educt stream in the upper area of the reactor and for a gaseous steam (3) in the lower area of the reactor (1). The reactor also comprises at least two chambers (4) that are arranged one above the other in the longitudinal direction, whereby the chambers (4) are separated from one another by liquid-tight bottoms. Each chamber is connected to the chamber (4) located directly underneath by a liquid overflow (6), and a liquid product stream is withdrawn via the liquid overflow (6) of the lowermost chamber (4). The gas space (7) above the liquid level in each chamber (4) is connected to the chamber (4) directly located thereabove by one or more gas feed pipes (8) each of which discharging into a gas distributor (9) with openings for discharging gas underneath the liquid level. The reactor also comprises at least one baffle plate (12), which is vertically arranged around each gas distributor (9) and whose upper end terminates underneath the liquid level and whose lower end terminates above the liquid-tight bottom (5) of the chamber (4). In addition, the baffle plate divides each chamber (4) into one or more gassed (13) spaces and into one or more ungassed (14) spaces.

摘要： Acrolein and acrylic acid are produced from propane and propene by absorption/desorption of propane and propene from a gas mixture followed by oxidation, in which no heterogeneously catalyzed dehydrogenation of propane occurs between the desorption and oxidation stages without addition of oxygen. Acrolein and acrylic acid are produced from propane and propene by: (a) separation of propane and propene from a gas mixture (A) by absorption in an absorption medium; (b) separation of propane and propene from the absorbent to give a mixture (B) containing propane and propene; and (c) using mixture (B) for oxidation to the required product(s). In this process, no catalytic dehydrogenation of propane without the addition of oxygen is carried out between stages (b) and (c).
