摘要：
Disclosed herein is a continuous process for preparing a silica product, comprising: (a) continuously feeding an acidulating agent and an alkali metal silicate into a loop reaction zone comprising a stream of liquid medium； wherein at least a portion of the acidulating agent and the alkali metal silicate react to form a silica product in the liquid medium of the loop reaction zone； (b) continuously recirculating the liquid medium through the loop reaction zone； and (c) continuously discharging from the loop reaction zone a portion of the liquid medium comprising the silica product. Silica products and dentifrice compositions comprising the silica products are also disclosed. A continuous loop reactor is also disclosed.本文揭示一種製備二氧化矽產物之連續方法，其包含：(a)將酸化劑及鹼金屬矽酸鹽連續饋入包含液體介質流之環流反應區中；其中至少一部分該酸化劑與該鹼金屬矽酸鹽在該環流反應區之液體介質中反應形成二氧化矽產物；(b)使該液體介質在該環流反應區中連續再循環；及(c)自該環流反應區連續排出一部分包含該二氧化矽產物之液體介質。亦揭示二氧化矽產物及包含該等二氧化矽產物之牙粉組成物。亦揭示一種連續環流反應器。
