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.
