Abstract: A specific form of surface coating of Al2O3 catalysts, using additional amounts of aluminium ions and minimum amounts of platinum ions, made it possible to use Al2O3 as a catalyst for long-term operation (150 days and more) in the preparation of hydrogen cyanide from hydrocarbons and ammonia, preferably in the BMA process.

Abstract: A process for preparing titanium disulfide for use as electrode material in batteries. The starting material to be purified has an approximate composition corresponding to TiS2, a content of free sulfur greater than 0.1 weight % and/or a particle diameter d90% greater than 10 mu m and is dispersed in an organic liquid that dissolves sulfur but not TiS2 in a shearing device, is then separated from the liquid phase, washed, and dried with exclusion of air.

Abstract: Polymeric complex compounds of molybdenum, tungsten, manganese, rhenium and of the metals of the sub-groups VIII and I of the Periodic Table of Elements, which complex compounds have a silica-type structure are disclosed. At least one amine (1) is bonded coordinately to the central metal atom. The atomic ratio of metal to nitrogen is from 1:1 to 1:106. The required charge compensation is effected by means of an anion. In (1), R1 and R2 represent a group (2) and R4 is an alkylene grouping. The oxygen atoms are saturated by silicon atoms of further groups (2), if appropriate with incorporation of crosslinking agents. R3 may have the meaning of R1 and R2, or represents hydrogen, an alkyl group, a cycloalkyl group or the benzyl group. The polymers can contain several metals. The invention also relates to processes for their preparation, and uses in catalysis.
