CONTINUOUS METHOD OF PRODUCING SILICON DIOXIDE Russian patent published in 2016 - IPC C01B33/18 

Abstract RU 2591242 C2

FIELD: chemistry.

SUBSTANCE: invention can be used for continuous production of silicon dioxide. Method comprises continuous feed of oxidising agent and alkali metal silicate in loop reaction zone containing liquid medium flow, where part of acidifying agent and alkali metal silicate reacts with formation of silicon dioxide. Liquid medium is continuously circulated through loop reaction zone, and its part together with silicon dioxide is continuously discharged from loop of reaction zone.

EFFECT: invention enables to continuously obtain silicon dioxide.
