MESOPOROUS NIOBIUM-SILICATE-PHOSPHATE COMPOSITE, METHOD OF PREPARING THE SAME AND METHOD OF PREPARING METHYLETHYL KETONE FROM 2,3-BUTANEDIOL USING THE SAME

摘要

PURPOSE: Mesoporous niobium-silicate-phosphate composite, a method for preparing the same, and a method for preparing methyl ethyl ketone based on 2,3-butanediol using the same are provided to secure the uniform distribution of pores in the composite. CONSTITUTION: Mesoporous niobium-silicate-phosphate composite includes niobium phosphate and silicate. The specific surface area of the composite is in a range between 132 and 262 m^2/g. A method for preparing the composite includes the following: a first solution is prepared by dissolving a niobium source in a solvent; a second solution is prepared by dissolving an organic template and phosphoric acid in the solvent; a third solution is prepared by adding a phosphate source and a linker compound, which links the phosphate and the silica, in the first solution; the second solution is added into the third solution to prepared a fourth solution; a silica source is added into the fourth solution and undergoes a solvothermal process the solvothermal treated solution is dried and plasticized.
