Abstract
PURPOSE: To enhance the catalytic effect of silica gel catalyst used in the synthesis of ketazine from ketone, ammonia and peroxide by using a specified fluorine compound as a gelling accelerator in gelling for preparing the catalyst.
CONSTITUTION: An aqueous soln. of sodium silicate is neutralized with acid, silicon tetrachloride is hydrolyzed in an aqueous soln., or silicic acid ester is hydrolyzed in the presence of acid or alkali as catalyst. When the resulting silicic acid or its polycondensate is allowed to gel, alkali metallic salt or ammonium salt of fluorine and their acidic salt are used as a gelling accelerator. The resulting silicic acid gel is then filtered, washed, dried, and calcined at about 180°C to obtain silica gel used as catalyst in the synthesis of ketazine from ketone, ammonia and peroxide.
