| titleOfInvention | Method for preparing epoxypropane |
| abstract | The invention discloses a method for preparing epoxypropane. The method comprises that (1) at 10-50 DEG C, a template, an inorganic silicon source and an inorganic titanium source are hydrolyzed with water to obtain a gel mixture; (2) the gel mixture is crystallized when the pH value is between 9-11, and products after the crystallization are filtered, dried and is subjected to the template removing to obtain a Ti-MCM-41 molecular sieve; and (3) with the existence of the Ti-MCM-41 molecular sieve which is prepared in the step (2) and a first organic solvent, propylene and organic peroxide are subjected to contact reaction, wherein the template is alkyl trimethyl ammonium bromide with the formula of R1Me3NBr, and R1 is C12-C22 straight-chain alkyl groups. By the method for preparing epoxypropane, the selectivity and yield of epoxypropane can be improved. |
