Abstract

PURPOSE: To produce silica sol while preventing formation of scale in stable operation over a long term by adjusting a silicate soln. to a specific acidic pH range and carrying out electrodialysis using an ion exchange membrane dialytic device composed of a pair of anion and cation exchange membranes.
CONSTITUTION: Using the above dialytic device a silicate soln. adjusted to pH 1W3 with mineral acid, e.g. a sodium silicate soln. is electrodialyzed to produce silica sol. At this time, it is desirable to carry out the ion exchange membrane electrodialysis at a temp. as low as possible, i.e. below 30°C besides to adjust the soln. pH value. The soln. is pref. regulated to a concn. of about 3W15% as silica.
