摘要： The invention relates to a method for producing a low-odor hydrogel-forming polymer based on acrylic acid, comprising the following steps: a) producing a polymeric hydrogel by radically polymerizing, in an aqueous polymerization medium, a monomer composition containing at least 50 wt. % of acrylic acid, and transforming the hydrogel into a particulate hydrogel or into a hydrogel-forming powder, and optionally; b) treating the particulate hydrogel or the hydrogel-forming powder with a crosslinking-active substance having at least two functional groups that react with the carboxyl groups of the polymer. The invention is characterized in that acrylic acid used in step a) contains less than 400 ppm ethanoic acid and/or propionic acid. The invention also relates to the hydrogel-forming polymers obtained according to said method, and to the use thereof.

摘要： The invention relates to a method for producing acrylic acid-based water-absorbent resins. Crude acrylic acid is first isolated from the reaction gases of the catalytic gas phase reaction of propane, propene, and/or acrolein. Said crude acrylic acid is treated with an aldehyde scavenger and pure acrylic acid is separated by distillation from the treated crude acrylic acid. The pure acrylic acid can then be immediately subjected to radical polymerisation.

摘要： The invention relates to a method for producing (meth)acrylic acid esters by transesterification of the (meth)acrylic acid with an alkanol in the presence of an acid catalyst, a polymerization inhibitor and an organic solvent that forms an azeotropic mixture with water. The reaction mixture is heated to the boiling point of the mixture in a reactor that comprises a distillation unit with a column and a condenser. The azeotropic mixture is distilled off, the organic solvent is returned to the column as reflux and at least a part of the column reflux is contacted with copper or a copper-containing material. The inventive method is advantageous in that substantially no polymerizate is produced in the distillation column.

摘要： The invention relates to a method for producing a tertiary C4-C8 alkyl (meth)acrylate by reacting (meth)acryl acid with an olefin of formula (I), wherein R?1 and R2¿, which can be identical or different, represent methyl or ethyl and R3 represents H, methyl or ethyl, in a homogeneous phase in the presence of an acidic catalyst and extracting the tertiary C¿4?-C8 alkyl(meth)acrylate from the reaction mixture. According to the invention, the catalyst is separated as a residue in a two-stage distillation of the reaction mixture and the tertiary C4-C8 alkyl(meth)acrylate is extracted from the distillation. The inventive method permits the use of (meth)acryl acid that contains acetic acid. The risk of a breakdown of the ester and the polymerization of the (meth)acryl compounds is reduced. The invention also relates to a falling film evaporator comprising a cylindrical casing (2), a plurality of evaporation tubes (3) located in said casing (2), means (4) for supplying the liquid to be evaporated and means (5) for heating the evaporation tubes (3). Said evaporator is characterised in that at least one evaporation tube (3) has a closed head region (6), into which a supply line (7) for the liquid to be evaporated opens, said supply line (7) communicating with the means (4) for supplying the liquid to be evaporated.

摘要： The invention relates to a method for producing (meth)acrylic acid from a mixture containing (meth)acrylic acid and a solution with a boiling point that is above the boiling point of (meth)acrylic acid by distilling the mixture in a column which is connected to an evaporator and provided with a stripping section and a fortification section between which the mixture is fed. Said column also contains a lateral discharge for the (methyl)acrylic acid. According to the inventive method, a polymerisation inhibitor is introduced into the head of the column and into the lateral discharge. The amount of polymerisation inhibitor introduced into the head of the column is less than the amount of said inhibitor which is introduced into the lateral discharge.
