ABSTRACT:
Disclosed is a method for producing propylene oxide wherein propylene is directly oxidized with oxygen, as required, water and a catalytic amount of hydrogen in a gas phase in the presence of a gold cluster catalyst supported on an alkali-treated titanosilicalite or mesoporous titanosilicate support, which is produced by an alkaline treatment of titanosilicalite or mesoporous titanosilicate with aqueous solution of NaOH, KOH or CsOH.
