Publication number: 20110009627Abstract: The invention relates to a reactor for performing high-pressure reactions, comprising at least one tube (31) whose ends are each conducted through a tube plate (33) and which is bonded to the tube plate (33). The tube plates (33) and the at least one tube (31) are surrounded by an outer jacket, such that an outer space (39) is formed between the tube (31) and the outer jacket. The tube plates (33) each have at least one surface composed of a nickel-base alloy and the at least one tube (31) is in each case welded on to the surface composed of the nickel-base alloy. The surface composed of the nickel-base alloy points in each case in the direction of the particular reactor end. The outer jacket has a thickness which is sufficient to absorb tensile forces which occur between tube (31) and outer jacket owing to a temperature difference in the event of different expansion. The invention further relates to a process for starting up the reactor and for performing an exothermic reaction in the reactor.Type: ApplicationFiled: January 21, 2009Publication date: January 13, 2011Applicant: BASF SEInventors: Helmut Schmidtke, Wilhelm Ruppel, Helmut Berrsche, Johann-Peter Melder, Udo Rheude, Petr Kubanek, Gerhard Ruf, Wolfgang Gunkel, Wolfgang Mägerlein, Karl-Heinz Ross
