Abstract: In a polysiloxane-based dental composition which crosslinks by an addition reaction and hardens at room temperature, the composition comprising(a) an organopolysiloxane with at least two vinyl groups in the molecule,(b) an organohydridopolysiloxane,(c) a catalyst to accelerate the addition reaction, and(d) a hydrophobic filler, the improvement which comprises including therein(e) an aluminosilicate containing finely divided palladium. This removes any by-product hydrogen and results in a smoother surface on any plaster of Paris moldings made from the hardened composition.

Abstract: Mixtures of m- and p-dichlorobenzene can be separated by treating such mixtures in the liquid phase with a pentasil zeolite at from 20.degree. to 250.degree. C., a filtrate enriched in m-dichlorobenzene being removed and the p-dichlorobenzene being obtained by desorption of the pentasil zeolite. The pentasil zeolites may contain, as exchangeable cations, protons, cations of the first or second main group of the Mendeleev Periodic System, cations of the rare earth metals or a mixture of a plurality thereof. In order to prepare the liquid phase a solvent is used that belongs to the group of cyclic saturated hydrocarbons having 5 to 15 carbon atoms, alkyl-substituted aromatic hydrocarbons having 8 to 12 carbon atoms, and halogen-substituted aromatic hydrocarbons having 6 to 10 carbon atoms and 1 to 3 halogen atoms. The solvents ethylbenzene, chlorobenzene, p-xylene, p-chlorotoluene and dichlorobenzene are excepted. A mixture of a plurality of these solvents may also be used.

Abstract: A process for the production of silica-bound zeolite granulates is disclosed, wherein zeolite to be formed into a granulate is mixed with silica sol. The process is carried out by adding aqueous alkali metal silicate to the silica sol immediately before the silica sol is mixed with the solid zeolite to be granulated. By the described process, granulates of various grain sizes can be obtained, and the resultant granulates can have a narrow grain size distribution.
