Abstract: PROBLEM TO BE SOLVED: To provide silica which possesses particularly good sorption characteristics for polar compounds because silica is frequently used as a carrier material for polar compounds such as choline chloride, propionic acid or formic acid. SOLUTION: Precipitated silica or a silicate can be obtained by acid precipitation of an aqueous silicate solution while maintaining a constant alkali number of at least 15-60.

SOLUTION: Foreign-atom-doped precipitated silica is provided which has a BET surface area of above 300 m 2 /g and has a maximum surface concentration of foreign atoms of 0.05 mmol/m 2 . The foreign atoms are added in the form of an organic salt or an inorganic salt at the time of precipitation. The foreign atoms or a solution of a salt thereof is added at the time of adding sulfuric acid or near the time (15 to 5 min) of completion of the simultaneous addition of sodium silicate and sulfuric acid. The foreign atoms are exemplified by Al, Zr, Zn, Ti, P, Cr, V, Sc, Ga, In, Fe, Ag, Sc, Mn, Co, Ni, and Cu. COPYRIGHT: (C)2007,JPO&INPIT

Abstract: Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung einer Fällungskieselsäure, wobei man Wasser vorlegt und Alkali- und/oder Erdalkalisilikat zugibt, bis sich ein pH-Wert von 8,0–10,8 einstellt, in diese Vorlage unter Rühren bei 50–95°C gleichzeitig Alkali- und/oder Erdalkalisilikat und ein Säuerungsmittel ohne Unterbrechung der Zudosierung zugibt bis ein Feststoffgehalt von größer 150 g/l erreicht ist, wobei das Säuerungsmittel auf den Scherkopf eines zusätzlichen Scheraggregats im Fällbehälter gegeben wird, anschließend mit einem Säuerungsmittel auf einen pH-Wert von ≤ 5,0 ansäuert, den Feststoff durch Filtration abtrennt und wäscht, trocknet und vermahlt. Die vorliegende Erfindung betrifft auch ein Verfahren zur Bestimmung des Schonabriebfaktors mit einem Abriebtestgerät, wobei man Prüfkörper aus gegossenem Polymethylmethacrylat einsetzt.
