    • A method for producing propylene oxide by reacting propylene with ethylbenzene hydroperoxide, wherein the reaction is conducted in the presence of a catalyst comprising a titanium-containing silicon oxide and satisfying all of the following conditions (1) to (6): (1) there is at least one peak showing a interplanar spacing (d) larger than 18 Å in X-ray diffraction; (2) an average pore size is 10 Å or more; (3) a pore size of 90% or more of the total pore volume is 5 to 200 Å; (4) a specific pore volume is 0.2 cm3/g or more; (5) a quaternary ammonium ion represented by the following general formula (I) is used as a template and then said template is removed by calcination operation: [NR1R2R3R4]+  (I) wherein R1 represents a linear or branched hydrocarbon chain having 2 to 36 carbon atoms, and R2 to R4 represent an alkyl group having 1 to 6 carbon atoms; and (6) The catalyst has been subjected to silylation treatment.
    • 一种通过丙烯与氢过氧化苯反应生产环氧丙烷的方法,其中反应在包含含钛氧化硅的催化剂存在下进行,并满足以下所有条件(1)至(6):(1) 是在X射线衍射中显示出大于18的晶面间距(d)的至少一个峰;(2)平均孔径为10埃以上;(3)总孔径的90%以上的孔径 体积为5〜200;(4)比孔体积为0.2cm 3 / g以上;(5)以下述通式(I)表示的季铵离子作为模板,将所述模板用 煅烧操作:其中R1表示具有2至36个碳原子的直链或支链烃链,R 2至R 4表示具有1至6个碳原子的烷基; 和(6)催化剂已进行甲硅烷基化处理。
