摘要 |
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: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. |
