Abstract: A closure cap, preferably a screw closure cap, for mounting on a liquid container includes at least a preferably recloseable pouring opening, a receiving element for receiving at least one dispensing body, e.g. a tablet, wherein the receiving element is permeable to a liquid so as to allow the at least one dispensing body to come into contact with the liquid, and an opening for introducing the at least one dispensing body into a receiving volume or for removing it from the receiving volume. In an operating state of the closure cap, the receiving element can be brought through the opening both from the receiving volume into a loading position for changing the dispensing body and also into the receiving volume to a dispensing position.

Abstract: A closure cap for mounting on a liquid container includes a preferably reclosable pouring opening and a receiving element which, with the closure cap, forms a common receiving volume for receiving at least one dispensing body, e.g. a tablet. The closure cap can be opened to create an access to the receiving volume and to be able to introduce the at least one dispensing body into the receiving volume or remove it from the latter, wherein the receiving element is permeable to a liquid in order to allow the dispensing body received therein to come into contact with the liquid. The access can be closed in a leaktight manner or opened by a closure element, which is connected to the closure cap and is movable by pivoting or sliding.

Abstract: In the overall methods of hydrogenating esters and maleic anhydride, which methods comprise a hydration reaction, comprising conducting the hydration reaction in the presence of the shaped Raney metal fixed-bed catalysts of the invention.

Abstract: Shaped Raney metal fixed-bed catalysts are doped with rhenium. Saturated or unsaturated esters are hydrogenated to their corresponding mono- or polyhydroxyalcohols.

Abstract: A shaped, activated, fixed-bed Raney metal catalyst prepared by a method comprising preparing a mixture of powders comprising at least one catalyst alloy of (1) at least one catalytically active Raney process metal, a leachable alloy component and optionally a promoter, (2) at least one binder containing at least one pure Raney metal and (3) a moistening agent. Shaping, calcining and activating said catalyst and doping said catalyst with rhenium.
