Abstract: A process for transporting a liquid monomer phase which has been withdrawn from a storage vessel and comprises methacrylic monomers to an extent of ≧90% by weight, in a tank truck or in a tanker ship, in which the liquid monomer phase is subjected to a separating operation on the route from the storage vessel into the tank of a tank truck or of a tanker ship in order to separate polymer of the monomer present in dissolved form in the liquid monomer phase.

Abstract: Beschrieben wird ein Katalysator zur Herstellung einer α,&bgr;-ungesättigten Carbonsäure durch Gasphasenoxidation eines α,&bgr;-ungesättigten Aldehyds, umfassend einen Trägerformkörper mit einer darauf aufgebrachten Aktivmasse, dadurch gekennzeichnet, dass die Aktivmassebedeckung qhöchstens 0,3 mg/mm2 beträgt, wobei Q der Aktivmasseanteil des Katalysators in Gew.-% und Sm die spezifische geometrische Oberfläche des Trägerformkörpers in mm2/mg ist. Beschrieben wird ferner ein Verfahren zur Herstellung des Katalysators sowie ein Verfahren zur Herstellung einer α,&bgr;-ungesättigten Carbonsäure durch Gasphasenoxidation eines α,&bgr;-ungesättigten Aldehyds an einem Katalysatorfestbett, das eine Schüttung des Katalysators umfasst. Durch den Katalysator wird bei fortdauernd hohem Umsatz an Acrolein die Überoxidation zu COx verringert und die Selektivität der Acrylsäurebildung erhöht.

Abstract: A method (M1) for mixing liquids or mixtures of liquids and finely-divided solids (I) in a closed tank where (I) fills only part of the available volume and the rest is filled by gas, by feeding in the same liquid or mixture (I) as a propulsive jet from a nozzle with a pulse-exchange space containing the jet nozzle outlet, in which the intake zone between jet nozzle and pulse-exchange space (PES) has a casing with at least one intake which is below the central jet leading from the nozzle to the PES. Independent claims are included for (1) a jet nozzle as above in which the casing has at least one intake opening into a dip tube or at least one connection for such a tube (2) a mixing method (M2) as above in which a different liquid or mixture is fed in as a propulsive jet .

Abstract: What is described is a process for producing water-absorbing resins, in which a) acrylic acid is prepared at an acrylic acid production site, b) the acrylic acid prepared is dissolved in water at the acrylic acid production site to obtain an aqueous acrylic acid solution, c) the aqueous acrylic acid solution is fed into a pipeline at the acrylic acid production site and passed through the pipeline to an acrylic acid processing site and d) the aqueous acrylic acid solution is subjected to a free-radical polymerization at the acrylic acid processing site. The process ensures safe transport of the highly reactive acrylic acid. Endangerment as a result of premature polymerization, as in the case of glacial acrylic acid, is ruled out, since the acrylic acid is “diluted” by the aqueous solvent and the specific heat capacity and the evaporation enthalpy of the water limit the maximum temperature rise. The amount of polymerization inhibitors used be reduced or it is possible to entirely dispense with polymerization inhibitors. Temperature control of vessels and pipelines within which the aqueous acrylic acid solution is conducted can be dispensed with because the solidification point of the aqueous acrylic acid solution is lower than that of anhydrous acrylic acid.

Abstract: Preparation of a catalyst consisting of a carrier body and a catalytic active mass, which is applied on the surface of the carrier body, comprises attaching one of the active mass to the surface of the carrier body with the help of a binding agent, where the active mass is a finely divided mixture of: at least an element of molybdenum and vanadium containing finely divided multielement oxides; and at least a finely divided substance comprising oxide of molybdenum or its compound, which forms its oxide under the effect of increased temperature and molecular oxygen. An independent claim is included for a catalyst, obtained by the above process.

Abstract: A process for rectificatively separating at least one (meth)acrylic monomer-containing fluid by feeding the fluid into a rectification column containing at least one sieve tray without a runoff segment, wherein an elementary cell is obtained from a number of centers of passages in a sieve tray, and the cell shifts regularly and repeatedly along its edges, the lengths of two shifting vectors being the lengths of the edges of the cell along which the shifting is effected; an arrangement of the centers is such that the positions of an ideal center and a real center are separated by
