Abstract: The invention relates to a method for the transportation of a monomer composition in which a composition comprising an aqueous solution of partially or entirely neutralized acrylic acid or overneutralized acrylic acid is placed in a transport means or sent through a pipe. The method according to the invention is characterized in that it has an increased level of safety during the transportation of acrylic acid monomers, an improved quality of the resulting product, and a high degree of efficiency. The method ensures safe transport of the highly reactive acrylic acid. The amount of polymerization inhibitors added to said acrylic acid may be reduced. An additional advantage is the minimization of the formation of dimeric acrylic acid. Tempering of containers, pipes, and pipelines may be omitted.

Abstract: A multitube fixed bed reactor and the use of such a reactor for carrying out catalytic gas-phase reactions, in particular for carrying out exothermic and endothermic catalytic gas-phase reactions such as the preparation of phthalic anhydride (PA), acrylic acid, methacrylic acid (MAA), acrolein, maleic anhydride (MA), glyoxal, phosgene, hydrocyanic acid or vinyl formamide (VFA). In a relatively large multitube reactor in which a large amount of heat of reaction is generated owing to the numerous catalyst tubes (17) and has to be removed, it is proposed that the ratio of tube spacing t to external tube diameter da be made dependent on the reactor diameter or on the external tube bundle diameter dRBa. At an external diameter of the catalyst tube bundle (18) of more than 4 meters, a ratio of tube spacing d to external tube diameter da of at least 1.3 is preferred.
