Abstract

PURPOSE: To enhance the yield of synthesis of ketazine from ketone, ammonia and peroxide by using silica gel catalyst prepared by gelling in the presence of a gelling accelerator and calcination at a specified temp.
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 in the presence of alkali metallic salt or ammonium salt of fluorine and their acidic salt as a gelling accelerator to form silicic acid gel. The gel is filtered, washed, dried at 150°C, and finally calcined at 150W600°C. When the silica gel catalyst thus obtd. is used in the synthesis of ketazine, the yield is enhanced.
