Abstract

PURPOSE: To enhance the catalytic activity and selectivity of silica gel catalyst for synthesizing ketazine from ketone, ammonia and peroxide by preparing the catalyst by gelling in a specified acidic liq.
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. The resulting silicic acid or its polycondensate is allowed to gel at 10W100°C in an acidic region of <6pH to form silicic acid gel. The gel is filtered, washed, peptized, dried at 150°C, and further dried at 180°C in a vacuum to obtain silica gel catalyst with superior catalytic characteristics and selectivity. The catalyst is used in the synthesis of ketazine from ketone, ammonia and peroxide.
