Process for modifying ts-1 based on mixed solution of quaternary ammonium salt and inorganic base |
| abstract |
This invention belongs to the technical field of inorganic chemical synthesis, relating to a modification method for titanium-silicalite zeolite (TS-1). The feature of the invention is pretreating the TS-1, after that the TS-1 is modified by the mixture of quaternary ammonium salts and inorganic base. The quaternary ammonium salts mentioned above include tetrapropylammonium fluoride, tetrapropylammonium chloride, tetrapropylammonium iodide and their mixture. The inorganic base include that LiOH, NaOH and KOH and their mixture. TS-1 after the modification is aftertreated at last. The benefit of the invention is universal capable to modify the TS-1 synthesized by any method, specially the TS-1 with low cost method, the modification can enhance the catalytic performance on both gas and liquid phase epoxidation of propylene. |
