    Abstract: An internal loop reactor comprises: a vertically disposed cylindrical vessel comprising a sidewall and reactor fluid outlet means; and at least one draft tube arranged vertically within the vessel. The draft tube(s) have/s an inner surface and an outer surface, wherein the draft tube(s) provide(s) (a) first conduit(s) within the draft tube(s) having a tube inlet end and a tube outlet end, and a second conduit outside of the draft tube(s) and within the sidewall, the first conduit(s) being in fluid communication with the second conduit. The reactor comprises at least one nozzle arranged concentrically to the draft tube(s) for injecting a fluid into the first conduit(s) from the tube inlet end. The inner surface of the draft tube(s) convexly curves so that the first conduit(s) exhibit(s) an annular constriction of the cross-section between the tube inlet end and the tube outlet end; wherein the constriction is located closer to the tube inlet end. Further, the outer surface of the draft tube(s) convexly curves, so that the draft tube(s) exhibit(s) a circumferential protuberance between the tube inlet end and the tube outlet end. The invention further relates to a process for performing a continuous high-pressure reaction, wherein a fluid is introduced into the internal loop reactor, and a reacted fluid is removed via the fluid outlet of the loop reactor. The curved shape of the inner surfaces of the draft tube wall(s) guides the fluid through the draft tube(s) in an optimized manner.

    Abstract: A method of measuring indices in superabsorbents, by initially charging excess aqueous solution or dispersion, swelling the superabsorbent in the initially charged aqueous solution or dispersion while stirring, dissolving or dispersing a component A in the aqueous solution or dispersion, measuring the enrichment of component A in the aqueous solution or dispersion during the swelling of the superabsorbent, using the enrichment of component A in the aqueous solution or dispersion to measure the time-dependent swelling characteristics and using these to determine the swelling constant k or the characteristic swell time τ, the index being dependent on the permeability of the superabsorbent, and ascertaining the index by means of a correlation measured beforehand between swelling constant k and index or characteristic swell time τ and index.
