Abstract: The invention relates to a process for the hydrogenation of halogen-substituted compounds of elements of Periods 2 to 4 of Groups III to V of the Periodic Table with the exception of gallium, aluminium, carbon and nitrogen, which is characterised in that …… a) finely-particulate aluminium is added to a salt melt composed of 50 to 67 mol% of AlCl3 (anhydrous) and 50 to 33 mol% of sodium chloride, … b) hydrogen is introduced into the stirred suspension, or the suspension which is dispersed by other means, so as to hydrogenate the finely-divided aluminium, … c) the resulting mixture is subsequently reacted with the halogen-substituted compound … and … d) the hydrogenated compound is isolated. …

Abstract: A precipitated silicic acid (I) has a BET (Brunauer Emmett Teller) surface area of at least 135 m /g and a CTAB (cetyltrimethylammonium bromide) surface area of at least 75 m /g. The ratio of BET/CTAB surface areas is at least 1.7. Independent claims are also included for the following: (1) a process for the preparation of the silicic acid (I); (2) vulcanizable rubber mixtures and vulcanizates containing (I); and (3) tires (I).

Abstract: Hydrogenation of halogen-substd. cpds. (I) of elements of the second to fourth periods of gps. III-V, except Ga, Al, C and N, involves reacting a salt melt of anhydrous AlCl3 and NaCl contg. finely-divided Al with H2 and (I). The novelty is that H2 and (I) are passed into the melt simultaneously.

Abstract: A method for the production of waterproof precipitated silica (I) involves (a) making a mixture of an organopolysiloxane derivative (II) and precipitated silica (III), (b) conditioning the mixture at 10-150 degrees C for 0.5-72 hours and (c) oxidative tempering at above 300 degrees C with an oxidizing gas.
