    Abstract: A process for starting up a separating process for purifying removal of acrylic acid crystals from a suspension S of crystals thereof in mother liquor with a hydraulic wash column which has a crystal melt circuit including crystal melt space, and a process space and a distributor space which are separated by an end with passages connecting the two spaces, in which the crystal bed is formed for the first time by first filling the crystal melt circuit and, at least partly, the process space with an acrylic acid-comprising startup liquid whose acrylic acid crystal formation temperature is less than or equal to the temperature of the suspension S increased by 15° C., and then continuing the filling of the wash column with the suspension S and optionally with control liquor until the difference between the pressure in the crystal melt space and the pressure in the distributor space falls suddenly, the arithmetic mean of the total waste liquor flow flowing through the filters of the filter tubes of the wash column until this time, based on the area of all filters, being not more than 80 m3/(m2·h).

    Abstract: Heterogeneously catalyzed partial gas phase oxidation of propylene to acrylic acid comprises introducing a reaction gas initial mixture (1) into a first reaction zone; reducing the temperature of the product gas mixture (1) by direct and/or indirect cooling, and adding a secondary gas to the product gas mixture (1); and subsequently introducing the product gas mixture (1), into a second reaction stage; and subsequently transferring the product gas mixture (2) containing acrylic acid in a first separation zone into the condensed phase and subsequently in a second separation zone. Heterogeneously catalyzed partial gas phase oxidation of propylene to acrylic acid comprises introducing a reaction gas initial mixture (1) containing propylene and molecular oxygen in a molar ratio of >=, 1 and at least an inert dilution gas in a first reaction stage, into a first reaction zone through at least a first catalyst bed at increased temperature, where the catalyst exhibit at least a multi-metal oxide (A) containing molybdenum, iron and bismuth as active mass, such that the propylene conversion during a single passage through the catalyst bed is >= 90 mol.% and the resulting selectivity of the acrolein- and acrylic acid by-product- formation is >= 80 mol.%; reducing the temperature of the product gas mixture (1) from the first reaction stage by direct and/or indirect cooling, and adding a secondary gas in the form of molecular oxygen and/or inert gas to the product gas mixture (1); and subsequently introducing the product gas mixture (1) as a reaction gas initial mixture (2) containing molecular oxygen and acrolein in a molar ratio of >= 0.5 and at least an inert dilution gas, in a second reaction stage at increased temperature by at least a second catalyst bed, whose catalysts exhibits multi-metal oxide (A1) containing at least an molybdenum and vanadium as active mass in such a way that the acrolein conversion during a single passage through the catalyst bed is >= 90 mol % and the selectivity of the acrylic acid formation over both the reaction stages is >= 70 mol %, with respect to converted propylene; subsequently transferring the product gas mixture (2) containing acrylic acid in a first separation zone into the condensed phase and subsequently in a second separation zone, where: the acrylic acid is separated from the condensed phase by application of at least a thermal separation process comprising at least a crystallization separation of the acrylic acid, and the reaction gas initial mixture (1) contains cyclopropane (up to 3 mol.%), with respect to the propylene.

    Abstract: A process for storing a monomer phase which is liquid under the conditions of storage and comprises methacrylic monomers to an extent of ≧95% by weight and has been obtained by condensation out of a gaseous phase or by melting a crystalline phase, in a storage vessel, in which polymer of the monomer present in dissolved form in the liquid monomer phase is removed therefrom on the route from its generation into the storage vessel, and also a process for withdrawing liquid monomer phase from the storage vessel in which polymer of the monomer present in dissolved form in the monomer phase is likewise removed.
