摘要： What is claimed is a dealuminated catalyst carrier, a process for producing a catalyst carrier with reduced aluminum content based on naturally occurring lattice-layer silicates, such as, for example, montmorillonite, as well as a process for the hydration reaction of C2- or C3-olefins in which said catalyst carrier with reduced aluminium content is used. For acid-catalysed hydration reaction the catalyst carrier is impregnated with phosphoric acid. The improvements according to the invention of the hydration reaction compared to conventional processes include the fact that no aluminium is leached out of the carrier in the presence of the phosphoric acid. As a result no more blockage of the succeeding apparatus due to aluminium phosphate is expected.

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： The invention is directed to the preparation of organic or aqueous-organic hydrogen peroxide solutions by direct synthesis from a non-explosive gaseous mixture containing hydrogen and oxygen. The process is carried out in the presence of a noble metal catalyst, using a reaction medium containing a halide and a strong acid. It can be performed in a stainless steel reactor without corrosion occurring to the reactor material if, during the reaction, the surface of the stainless steel is, at no place, in permanent contact with the gaseous mixture passing through the reactor.
