A method for producing propylene oxide which comprises reacting propylene, oxygen and hydrogen, in the presence of a titanosilicate and a noble metal supported on silylated active carbon, in a solvent.
A method is for producing propylene oxide, the method including the steps of: reacting hydrogen peroxide with propylene either in an acetonitrile solvent or in a mixture of solvents which include acetonitrile and water, in presence of a titanosilicate catalyst, whereby a reaction mixture containing propylene oxide is obtained; separating the reaction mixture obtained in the reacting into a gas and a reaction liquid; and distilling the reaction liquid obtained in the separating, whereby the reaction liquid is separated into a column top liquid containing propylene oxide, and a column bottom liquid including acetonitrile or a combination of acetonitrile and water, in combination with other steps. This enables industrially efficient production of propylene oxide with use of acetonitrile.

There is provided a method for producing a mixed gas which contains a combustion assisting gas and a combustible gas characterized in that the method includes the steps of:
(1) mixing a [combustion assisting gas and inert gas]-containing gas which contains the combustion assisting gas and an inert gas with the comestible gas so as to prepare a [combustion assisting gas, inert gas, and combustible gas]-containing gas which contains the combustion assisting gas, the inert gas, and the combustible gas; and
(2) reducing an amount of the inert gas contained in the [combustion assisting gas, inert gas, and combustible gas]-containing gas.
Such method is used for the production of a mix gas which further contains another combustible gas.
A method for producing an oxidized compound according to the present invention comprises reacting an organic compound with an oxidizing agent in the presence of titanosilicate (I) or a silylated form thereof, the titanosilicate (I) being obtained by contacting titanosilicate (II) with a structure-directing agent, and the titanosilicate (II) having an X-ray diffraction pattern reproduced in the form of interplanar spacings d of
