-- 23- MESOPOROUS NIOBIUM-SILICATE-PHOSPHATE COMPOSITE METHOD OF PREPARING THE SAME AND METHOD OF PREPARING METHYLETHYL KETONE FROM 23-BUTANEDIOL USING THE SAME

摘要

The niobium-silicate-phosphate composite catalyst according to an embodiment of the present invention is easily separated from the product and can have high activity. In addition, the niobium-silicate-phosphate composite catalyst has excellent mesopore structure and uniform pore distribution. Further, the selectivity and yield of methyl ethyl ketone can be improved when methyl ethyl ketone (MEK) is prepared using the niobium-silicate-phosphate composite catalyst according to an embodiment of the present invention.
