Abstract: A process is proposed for partial oxidation oxidation in the gas phase of C3 and/or C4 precursor compounds to (meth)acrolein and/or (meth)acrylic acid in the presence of a heterogeneous particulate catalyst in a reactor having one or more cuboidal thermoplate modules (1) which are each formed from two or more rectangular thermoplates (2) arranged parallel to each other while in each case leaving a gap (3) which can be filled with the heterogeneous particulate catalyst and is flowed through by the fluid reaction mixture; the heat of reaction being absorbed by a heat carrier which flows through the thermoplates (2) and thus at least partly evaporating, and also having a predominantly cylindrical shell (4, 15, 16) which releases the pressure at the thermoplate modules, completely surrounds them and comprises a cylinder jacket (4) and hoods (15, 16) which seal it at both ends and whose longitudinal axis is aligned parallel to the plane of the thermoplates (2), and also having one or more sealing elements (7, 2

Abstract: The invention relates to a method for producing (meth)acrylic acid esters IV by means of transesterification of a (meth)acrylic acid ester I with an alcohol R2OH comprising at least one more carbon atom than the alcohol constituents (R1O—) in the (meth)acrylic acid ester I to be subjected to transesterification, in the presence of a catalyst or a catalyst mixture. Either essentially the (meth)acrylic acid ester I is separated and then the catalyst used is separated by distillation (catalyst separation), or the catalyst used is separated by distillation first (catalyst separation), and then essentially the (meth)acrylic acid ester I is separated, from the reaction product of the transesterification. Constituents from the mixture obtained, which have a lower boiling point than the (meth)acrylic acid ester IV, are essentially separated by distillation (separation of constituents at low boiling point), and the (meth)acrylic acid ester IV is then purified by distillation (purification by distillation).

Abstract: An improved method of manufacturing surface-crosslinked superabsorbent polymer particles is disclosed. The superabsorbent polymer particles are surface crosslinked using about 20 to about 35 wt % of 1,3-propanediol as a cosolvent in a surface-crosslinking step. The use of 1,3-propanediol as a cosolvent reduces the amount of surface-crosslinking agent required to adequately surface crosslink the superabsorbent polymer, and reduces or eliminates the fouling of process equipment attributed to previous cosolvents used in a surface crosslinking step.
