The mixture has a first coarse-grained component and a second fine-grained component, with a primary grain size of preferably d50(1) between 0.3 μm and 0.5 μm and d50(2) of at most 0.05 μm, respectively (with an agglomerated size of the fine particles of less than 0.15 μm).
Abstract:
In a process for preparing alkylamines by reacting olefins with ammonia, primary or secondary amines under hydroaminating conditions over a calcined zeolitic catalyst, the calcined zeolitic catalyst is thermally activated at from 100 to 550° C. in a gaseous stream of air, nitrogen, other inert gases or mixtures thereof not more than 24 hours before commencement of the reaction.
Abstract:
The present invention relates to a process for the preparation of hydrogen peroxide from oxygen or oxygen-delivering substances and hydrogen or hydrogen-delivering substances in the presence of at least one catalyst containing a metal-organic framework material, wherein said framework material comprises pores and a metal ion and an at least bidentate organic compound, said bidentate organic compound being coordinately bound to the metal ion. The invention further relates to a novel material consisting of said metal organic framework material wherein the material is brought in contact with at least one additional metal.
Abstract:
Cycloalkano-indole and -azaindole derivatives are prepared by reaction of appropriately substituted carboxylic acids with amines. The cycloalkano-indole and -azaindole derivatives are suitable as active compounds for medicaments, preferably antiatherosclerotic medicaments.
Abstract:
The invention relates to a process for the utilization of a feedstock essentially comprising nitrogen-organic compounds, in which the utilization takes place by gasifying the feedstock under normal pressure or an increased pressure, up to 40 bar, at temperatures at least about 900° C., and preferably between 1100° C., and 1600° C., by partial oxidation using a gasifying medium containing free oxygen, as a flame reaction in an entrained bedgasifier. An apparatus for carrying out the process is described.
Abstract:
In a continuous process for reacting an organic compound with hydroperoxide in the presence of a catalyst, the reaction is carried out in a reactor assembly comprising at least two reactors connected in parallel.
Abstract:
The invention relates to a combined mechanical and key comprising a key housing for electronic components and an L-shape flat key (30). Said flat key consists of a bearing limb (31) which enables the key to pivot into a storage position and a shank (32) which mechanically operates the lock. The shank (32) of the flat key (30) can be displaced between an inoperative position, retracted into the key housing and an operative position, in which it projects out of the hosing. A push-button preferably also acts as the pivoting axis for the flat key (30). The push-button and the housing have profiled sections and the bearing limb has co-operating profiled sections (37, 38, 39), to subject the flat key (30) to a force in the operative position and to lock the key in one of its positions. The invention aims to produce a simple, cost-effective key. To this end, the flat key is configured as a planar plate (34) with an L-shaped outline, the shank (32) sharing the same plane as the bearing limb. The bearing limb (31) has an opening (35) in the plate for receiving, in a rotationally fixed manner, an insert (36) that has the co-operating profiled section (37 to 39).
