titleOfInvention |
Process for the preparation of precipitated silicas, precipitated silicas and their uses, in particular for the reinforcement of polymers |
abstract |
The present invention relates to a novel process for the production of precipitated silica, wherein a silicate is reacted with an acidifying agent, resulting in a silica suspension; The silica suspension is filtered, resulting in a filter cake; the filter cake is subjected to a liquefaction process in the absence of an aluminum compound; Methylglutaric acid is also added to the filter cake during or after the liquefaction process. The present invention also relates to novel precipitated silica and uses thereof. |
