Abstract: The present invention relates to dust-free preparations dispersible in cold water. These preparations consist of particles comprising water-insoluble or only sparingly water-soluble active substance(s), said particles being coated with one or more layers, the outermost layer comprising as principal component one or more hydrophobic powdering agents on which at least one dispersant is absorbed. The invention also relates to a process for producing these particles and to the use thereof in food supplements, foodstuffs, animal feeds, personal-care products, and medicaments.

Abstract: A method and service for handling incoming customer calls. The invention uses an Access Point Model (APM) that includes an inventory of access entry points for voice, text, and/or web communication from a customer; a process network that lists the names and roles of customer contacts within the enterprise; an APM diagram of optimized pathways to be taken by particular incoming customer calls; rules for the customer contacts to follow when handling the incoming customer calls; and a synchronization of the customer calls with back-end processes within the enterprise that are responsive to instructions from the customer contacts.

Abstract: A column is described for carrying out reactive distillations in the presence of a heterogeneous particulate catalyst having an ordered packing or random packings which form intermediate spaces in the column interior, the quotient of the hydraulic diameter for the gas flow through the ordered packing or the random packings and the equivalent diameter of the catalyst particles being in the range from 2 to 20, preferably in the range from 5 to 10, in such a manner that the catalyst particles are introduced into the intermediate spaces, distributed and discharged loose under the action of gravity.

Abstract: A process is proposed for the distillation or reactive distillation of a mixture that includes at least one toxic component, the process being carried out in a column containing a structured packing, having at least one packing layer (1) having a lower end (2) and an upper end (3), the packing layer having an internal geometry varying over its height, in such a manner that in the distillation or reactive distillation, in a first, lower region (6) of the packing layer (1) a bubbling layer having a predominantly disperse gas phase can be established and simultaneously in a second, upper region (7) of the packing layer (1) a film flow having a predominantly continuous gas phase can be established.

Abstract: The present invention relates to a process for preparing tetrahydrogeranylacetone (tetrahydropseudoionone) by aldol condensation of citral with acetone and subsequent hydrogenation. The invention further relates to the use of thus obtained tetrahydro-geranylacetone for preparing phytol, isophytol, tocopherol and/or tocopherol derivatives. In addition, the invention relates to processes for preparing tocopherols and/or tocopherol derivatives.

Abstract: A process is described for preparing tetrahydrogeranylacetone in which pseudoionone, geranylacetone and/or dihydrogeranylacetone in a liquid phase, in which particles of a catalyst which is capable of preferentially hydrogenating carbon-carbon double bonds over carbon-oxygen double bonds are suspended, is conducted through a device which inhibits the transport of the catalyst particles in the presence of a hydrogen-containing gas.

Abstract: A dividing-wall column having a dividing wall which is essentially disposed along the long direction of the column is proposed, which divides the column interior into a feed part, a take off part, an upper shared column part and a lower shared column part, with feed in whole or in part in the vaporous state of a mixture to be separated between the upper region of the feed part and the lower region of the feed part and/or side stream take off in whole or in part in the vaporous state between the upper region of the take off part and the lower region of the take off part, where if feed is in whole or in part in the vaporous state the cross-sectional area of the upper region of the feed part is increased by plane-parallel displacement of the dividing wall toward the upper region of the take off part, and/or if the side stream take off is in whole or in part in the vaporous state, the cross-sectional area of the lower region of the take off part is increased by displacement of the dividing wall toward the lower r

Abstract: An injection molding machine for producing shaped plastic parts has at least one injection mold and at least one removal unit with which shaped plastic parts are removed from the at least one injection mold. The shaped plastic parts are put down in a controlled way while the at least one injection mold is in a closed position. At least one putting-down unit is provided and the at least one removal unit transfers the shaped plastic parts to the at least one putting-down unit. The putting-down unit places the shaped plastic parts into at least one receptacle.

Abstract: The invention relates to a continuous process for producing pseudoionones of general formulas (I) and (I?) as well as isomers thereof, whereby: R1 represents CH3 or (a); R2 and R3 represent hydrogen, CH3 or C2H5, and; R4 and R5 represent hydrogen or CH3. These pseudoionones are produced by reacting an aldehyde of formula (II) with an excess of a ketone of general formula (III), whereby R1, R2 and R3 have the aforementioned meanings, in the presence of water and alkali hydroxide at an increased temperature and in a homogeneous solution. The inventive process is characterized in that: a) the intermixing of the homogeneous solution consisting of aldehyde, ketone and aqueous alkali lye occurs at a temperature ranging from 10 to 120° C.
