Abstract: The invention relates to a method for producing acrylic acid by means of two-stage heterogeneously catalyzed partial gas phase oxidation of propylene. According to said method, previously dehydrogenated propane is used as a propylene source while the first partial oxidation stage is operated so as to limit propylene reaction. Furthermore, unreacted propane and propylene contained in the product gas mixture of the second partial oxidation stage are largely redirected into the propane dehydrogenation process taking place upstream.

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 .
