Abstract: In the method for the chemical reaction of gaseous educts the educts are brought to reaction in a phase contact apparatus 1 in the presence of a catalytically active corrosive liquid. This corrosive liquid is delivered hydropneumatically in an intermittent cycle in the circuit from a sump vessel 4 connected to the lower end of the phase contact apparatus 1 to a supply vessel 9, connected to the upper end of the phase contact apparatus (delivery cycle), from which the corrosive liquid drains through the phase contact apparatus 1 and a connecting line 11 connected at its lower end and then collects in the sump vessel 4 (drainage cycle).

Abstract: A self-cleaning reactor/mixer, in particular a disk reactor, with a large available useful capacity, which cleans itself kinematically, comprising at least two or more parallel shafts rotating in the same direction, on which axially offset, not necessarily circular disks with scrapers distributed on their circumference are situated, and a surrounding housing. The reactor/mixer on account of the special geometry of its rotors, which extensively avoids acute product-side angles, is particularly suitable for processing solids-bearing materials to be mixed.

Abstract: An improvement in a process for inactivating extracellular and intracellular viruses in a platelet containing composition is presented. The improvement in the process comprises adding a sensitizer to the platelet containing composition and irradiating the composition containing the sensitizer with UVA1 in the absence of UVA2 for a period of time sufficient to inactivate the viruses while retaining the functionality of the platelet containing composition. A quencher or mixture of quenchers of type I and type II photodynamic reactions may be advantageously added to the composition prior to irradiation.

Abstract: Use of one or more hydrophobicized, pharmaceutically or cosmetically acceptable inorganic pigments in cosmetic or dermatological preparations for preventingleaching out or washing off of the skin's cis- or trans-urocaninic acid from the human skin, caused by the action of water, orleaching out or washing off of cis- or trans-urocaninic acid which has been applied artificially to the skin, from the human skin caused by the action of water.

Abstract: 4-Fluorothiophenol is obtained in outstanding purifies and yields if 4-fluorobenzenesulphonyl chloride is reacted with sodium hydrogen sulphite solution to give a solution of sodium 4-fluorobenzenesulphinate, this solution is reduced with sulphur dioxide to give 4,4'-difluorodiphenyl disulphide and finally this is reacted with sodium borohydride in a water-miscible inert organic solvent to give 4-fluorothiophenol (sodium salt). Free 4-fluorothiophenol can be isolated from the sodium salt solution by acidification.

Abstract: The device for continuous filtration and drying of a solid suspension comprises a belt filter (1) and downstream a belt drier (2). By means of a porous conveyor belt (3) the filter cake generated in the belt filter (1) is conveyed further into the belt drier (2) in which there are provided heating devices for heating and drying the filter cake (7) which is on the conveyor belt (3). After leaving the belt filter (1), the filter cake (7) is present on the conveyor belt (3) in the form of a gas-permeable bed of solids in layer form having a maximum layer thickness of 50 mm, preferably a maximum of 20 mm. The heating devices in the belt drier comprise, on the one hand, a hot gas chamber (8) disposed above the conveyor belt (3) to generate a hot gas which flows through the bed of solids downwardly from above and, on the other hand, one or more contact heating elements (10, 15, 18, 19, 20, 22) disposed above and/or below the conveyor belt (3).
