Abstract: The present invention relates to an integrated process for the synthesis of propylene oxide, which comprises at least the following steps: (i) dehydrogenation of propane to give a substream T( 0 ) comprising at least propane, propene and hydrogen; (ii) fractionation of the substream T( 0 ) to give at least one gaseous hydrogen-rich substream T( 2 ) and a substream T( 1 ) comprising at least propene and propane; (iii) synthesis of hydrogen peroxide using the substream T( 2 ), giving a substream T ( 4 ) which is rich in hydrogen peroxide and a gaseous substream T( 6 ); (iv) fractionation of the substream T( 1 ) to give at least one propane-rich substream T( 5 ) and at least one propene-rich substream T( 3 ); (v) reaction of the at least one substream T( 3 ) with substream T( 4 ) to give propylene oxide.
