摘要： The invention relates to a process for increasing the selectivity of the hydrogenation of 4,4′-diaminodiphenylmethane (4,4′-MDA) to diaminodicyclohexylmethane (4,4′-HMDA) by catalytic hydrogenation of a mixture containing 4,4′-MDA as the main component and its mono-N-methyl derivative as a secondary component. According to the invention, the hydrogenation is terminated before a conversion of 4,4′-MDA to 4,4′-HMDA of 99% is achieved. Under these conditions, a substantially smaller proportion of the N-methyl-4,4′-MDA is hydrogenated to N-methyl-4,4-HMDA.

摘要： An impeller for a delivery pump in which profiled section (14) comprising webs (15) is located on the outer periphery of an impeller (4) for a feed pump (2) that is configured as a side channel pump. The webs (15) are arranged at an ascending incline, viewed in the rotational direction of the impeller (4) from the designated pressure side to the designated intake side. This permits flow losses between the radial external region of the impeller (4) and the housing parts (6, 7) of the feed pump (2) to be maintained at a particularly low level.

摘要： Carrier-bound ruthenium catalysts are used to produce alcohols by the catalytic hydrogenation of aldehydes and ketones. The problem of deactivation of the catalyst is solved by the use of a ruthenium catalyst on an oxide carrier of the series TiO2, SiO2, ZrO2, MgO, mixed oxides thereof and silicates thereof. In particular, Ru on TiO2 or SiO2 results in a long service life of the catalyst.

摘要： In a fuel pump (6) designed as a side channel pump, in each case two conveying chambers (20-23) one surrounding the other concentrically are arranged on two impellers (9, 10). The conveying chambers (20, 21) of one impeller (9) are connected to an inlet duct (25), while the conveying chambers (22, 23) of the other impeller (10) are connected to an outlet duct (26). A connection (24) of the conveying chambers (20-23) is arranged in a partition (17) keeping the impellers (9, 10) at a distance from one another. As a result, the fuel pump (6) has an especially high volume flow, along with a very high conveying pressure.
