Abstract: Column plates for a material exchange column, esp. with a peripheral supporting ring and supporting elements holding plates with through-holes, esp. perforations, valves or bubble caps comprise: (1) a liquid-tight join, pref. weld, esp. in discrete areas, between (a) the plates and the supporting elements and/or ring, (b) the supporting elements and (c) the supporting elements and the wall of the column or supporting ring; and (2) adjacent plates and supporting elements are sepd. from one another and from the column wall or supporting ring by gaps with a width of 1-15, pref. 1-7 mm. Also claimed are material exchange columns with plates of this type and a method of producing the plates.

Abstract: In a separator (11), designed to separate mixtures composed of liquids of various densities, the inflow (12) of the liquid mixture is so arranged and so designed that the inflowing liquid mixture hits an inner wall(16), located opposite the separator outflows, at an angle alpha of 0 DEG - 45 DEG relative to the normal to the container wall. Such a separator can be used in the manufacturing process for acrylic acid through catalytic vapour-phase oxidation of propene.

Abstract: In the production process for acrylic acid through catalytic vapour-phase oxidation of propene, acrylic acid is separated from the vapour-phase oxidation reaction mixture by means of an absorbing agent containing diphenyl, diphenyl ether or dimethyl phthalate and is also extracted from the vapour-phase oxidation acidic water by means of a solvent containing diphenyl, diphenyl ether or dimethyl phthalate.
