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 obtain a partial stream T (0), which contains at least propane, propene and hydrogen; (ii) separation of the partial stream T (0) to obtain at least one gaseous partial stream T (2) with a high hydrogen content and a partial stream T (1), which contains at least propene and propane; iii) hydrogen peroxide synthesis using the partial stream T (2), to produce a partial stream T (4) with a high hydrogen peroxide content and a gaseous partial stream T (6); (iv) separation of the partial stream T (1) to obtain at least one partial stream T (5) with a high propane content and at least one partial stream T (3) with a high propene content; (v) reaction of the partial stream(s) T (3) with partial stream T (4) to obtain propylene oxide.
