    摘要: Disclosed is a method for the purification of exhaust air and/or effluents, which may be exhausted, for example, from auto painting units or furniture lacquering units, involving contacting the air and/or effluents with a molded body. The molded body is made from dealuminated zeolite Y and at least one binder, which may be, for example, bentonites, kaolins, sepiolites or attapulgites, and having a hydrophobic factor of from 1.5 to 6.0, wherein a slurry of the binder in water does not exceed a pH of 10 and wherein the molded body is calcined at 850° to 1100° C. The molded body is produced by a process involving mixing pulverulent dealuminated zeolite Y with at least one binder, optionally with the addition of a lubricant and/or a pore former, and optionally with water or an organic solvent, moulding the resulting mass to form a molded body, and drying and calcining the molded bodies.

    摘要: Molecular sieves are modified by an ion exchange process where metal cations are introduced into the molecular sieves by means of solid state ion exchange. The solid state ion exchange can be carried out as follows: a weighed amount of calcined and activated zeolite is intimately mixed with a precalculated amount of PtCl.sub.2, PdCl.sub.2, RhCl.sub.3, CuCl.sub.2, V.sub.2 O.sub.5 or another compound of the noble metals (e.g., corresponding halides or oxides), the solids mixture is then heated in a current of inert gas (e.g., a current of helium gas or of nitrogen) to temperatures of 400.degree. to 600.degree. C., then cooled down to room temperature and subsequently reduced in a current of hydrogen for 10 to 14 hours at 280.degree. to 350.degree. C. in order to produce small metal clusters from the cationically introduced metal.

    摘要: The invention relates to a process for preparing a dental material filler in the form of a copolycondensate. An alkoxy silane having a formula of Si(OR.sup.3).sub.4 and a titanium compound are dissolved in a water-miscible solvent. Optionally, additional alkoxysilanes having the formulas R.sup.1 --Si(OR.sup.3).sub.3 and R.sup.2.sub.2 Si(OR.sup.3).sub.2 are also dissolved in the solvent. The reactants are hydrolyzed and condensed to form a reaction mixture from which a heterosiloxane is formed. The heterosiloxane is separated, optionally washed, dried and tempered. The heterosiloxane may then be ground to a desired size and/or formed into various dental materials, such as fillings, inlays, veneers, seals, crowns, bridges, dentures, artificial teeth and adhesives for dental materials. Alternatively, the reaction may take place without the use of a water miscible solvent, such that the precondensing takes place in water.
