Abstract: PROBLEM TO BE SOLVED: To provide a method for producing an alkene by partially hydrogenating a 10-30C alkyne. SOLUTION: A palladium compound or, if needed, other metal ion is applied to a heat treated and cooled support material by impregnating a solution containing a palladium salt or, if needed, other metal ion and subsequent drying and 10-2,000 ppm of carbon monoxide (CO) is added or a corresponding amount of CO is generated by a slight decomposition of a compound capable of releasing CO under the reaction condition and added to the reaction mixture.

Abstract: Production of alkenes by liquid-phase hydrogenation of alkynes containing 10-30 carbon (C) atoms comprises using a monolithic supported palladium catalyst and hydrogen containing 10-2000 ppm carbon monoxide (CO). Production of alkenes by liquid-phase hydrogenation of alkynes containing 10-30 C atoms at 20-250 degrees C and a hydrogen partial pressure of 0.3-200 bar comprises: (a) using a fixed bed of a catalyst prepared by calcining a support material in air, cooling it, impregnating it with a solution containing a palladium salt and optionally other metal ions, drying the product and shaping it into a monolithic catalyst element; and (b) either adding 10-2000 ppm CO to the hydrogen or generating an equivalent amount of CO by adding a CO-releasing compound to the liquid phase.

Abstract: The invention relates to chiral compounds containing at least one divalent or polyvalent chiral group, at least one polymerizable group, at least one spacer and at least one mesogenic group, and to their use as polymerizable, chiral dopes for the preparation of cholesteric networks. The novel compounds are suitable for use in electro-optical displays or as chiral dopes for nematic or cholesteric liquid crystals in order to produce layers which reflect in colors.
