An adsorbent for organic compounds consisting of filler granules, which contain 20 to 99.9 wt. % of fillers and a binder. The adsorbent is produced by mixing at least one binder with at least one filler and performing granulation in a mixing or granulation apparatus. The adsorbent may be used for adsorbing and/or absorbing organic and/or inorganic substances from a liquid or gaseous phase.

Rubber compositions comprising a precipitated silica with the following physico-chemical properties: 

Precipitated silicas

A precipitated silica with the following physicochemical properties: is produced by reacting alkali silicate with mineral acids at temperatures of 60&#xb0; C. to 95&#xb0; C. while maintaining a pH of 7.5 to 10.5 and continuously stirring, continuing the reaction to a solids concentration in the precipitation suspension of 90 g/l to 120 g/l, adjusting the pH value to a value of less than or equal to 5, filtering out, washing, drying and optionally grinding or granulating the precipitated silica. The precipitated silica is used as a filler in vulcanizable rubber compounds and vulcanizates.
