Abstract: Process for the continuous production of an optically active carbonyl compound by asymmetric hydrogenation of a prochiral α,β-unsaturated carbonyl compound with hydrogen in the presence of a homogeneous rhodium catalyst that has at least one chiral ligand, wherein a liquid reaction mixture comprising the prochiral α,β-unsaturated carbonyl compound is subjected in a first, backmixed reactor to a gas/liquid two-phase hydrogenation, and the liquid reaction mixture is then further hydrogenated in a second reactor, wherein the prochiral α,β-unsaturated carbonyl compound is employed in the first reactor in a concentration from 3% to 20% by weight. The process allows a high total conversion to the prochiral α,β-unsaturated carbonyl compound.

Abstract: The invention relates to a method for the surface processing of a component by flow grinding, comprising the following steps: (a) providing a blank (1), (b) flooding at least one surface of the blank (1) with a fluid carrier material containing grinding particles, wherein the blank (1) is rounded at positions at which, during flooding, the flow direction (25) of the fluid carrier material containing the grinding particles changes and, at positions at which a flow separation occurs on the finished component, additional material (5) is attached such that a flow separation at the beginning of the flooding operation is prevented.

Abstract: The present invention refers to a method for controlling undesired vegetation at a plant cultivation site, the method comprising the steps of providing, at said site, a plant that comprises at least one nucleic acid comprising a nucleotide sequence encoding a wild-type hydroxyphenyl pyruvate dioxygenase or a mutated hydroxyphenyl pyruvate dioxygenase (mut-HPPD) which is resistant or tolerant to a HPPD-inhibiting herbicide and/or a nucleotide sequence encoding a wild-type homogentisate solanesyl transferase or a mutated homogentisate solanesyl transferase (mut-HST) which is resistant or tolerant to a HPPD-inhibiting herbicide, applying to said site an effective amount of said herbicide. The invention further refers to plants comprising mut-HPPD, and methods of obtaining such plants.

Abstract: A polymer composite contains tubular particles, which contain at least one resin with fibres embedded. The tubular particles have an average length in the range of 0.5 mm to 60 mm and an average wall thickness in the range of 0.0005 mm to 30 mm, whereas the fibers have an average diameter in the range of 0.0005 mm to 5.0 mm. A process can be used to prepare the polymer composite containing tubular particles. The polymer composite can be used as a cushioning material, which can be formed into a cushioning article such as a shoe sole, a furniture cushion, a bed mattress, an automotive seat cushion, a flooring substrate, an outdoor/walking surface, a mat, a pad, and the like.
