    Abstract: The invention relates to a method for producing alkyl(meth)acrylate by continuous reaction of an aqueous solution containing (meth)acrylic acid obtained directly from gas-phase oxidation by reacting with a straight-chain or branched alkanol with 1 to 6 C atoms or a mixture of two or more thereof in the presence of an esterification catalyst. The inventive method is characterized in that alkanol is introduced into aqueous solution containing (meth)acrylic acid in the form of a gas.

    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 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~ - 45~ 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.
