| titleOfInvention | A kind of olefin epoxidation catalysts and preparation method thereof |
| abstract | The present invention relates to a kind of olefin epoxidation catalysts, and for modified Titanium Sieve Molecular Sieve, aperture is 10~30nm, and TiO content is 0.5~10wt%, 1.0~1.5ml/g of Kong Rong, pore-size distribution rate >=93.5%, 150~500m of specific surface area 2 /g.Preparation method: template, template modifying agent, water and solvent, heating stirring being added into reactor, and silicon source is then added, and heat preservation filters, obtains molecular screen primary powder after drying；Molecular screen primary powder extrusion aid, adhesive and impregnation agent are uniformly mixed, dry after extrusion moulding, roasting obtains molded molecular sieve；Molded molecular sieve plus titanium source are prepared into Titanium Sieve Molecular Sieve, be eventually adding surface modifying agent to get.Catalyst of the invention is suitable for catalysis isopropyl benzene hydroperoxide propylene oxide, and isopropyl benzene hydroperoxide high conversion rate, propylene oxide selectivity is high, and by-product phenol is less. |
