    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.

    Abstract: A process for the continuous preparation of hydroxylammonium salts by catalytic reduction of nitrogen monoxide by means of hydrogen in a dilute aqueous solution of mineral acid in a plurality of reaction stages connected in series comprises dividing the incoming stream of dilute aqueous solution of mineral acid into at least two substreams before it is fed into the plurality of reaction stages connected in series, feeding a first of these substreams to the first reaction stage, feeding a second of these substreams to a reaction stage other than the first, where the inflow of dilute aqueous solution of mineral acid into the plurality of reaction stages connected in series is controlled by means of the pH in this reaction stage other than the first.

    IPC: C01B21/00 ,  C01B21/14

    Abstract: The invention relates to a method for continuously producing hydroxyammonium salts by catalytically reducing nitrogen monoxide with hydrogen in a diluted aqueous solution of mineral acid in a plurality of series-connected reaction stages. The inventive method is characterized in that the inflow of the diluted aqueous solution of mineral acid is split into at least two partial streams prior to being supplied to the plurality of series-connected reaction stages. A first partial stream is supplied to the first reaction stage. A second partial stream is supplied to a reaction stage other than the first reaction stage, whereby the inflow of diluted aqueous solution of mineral acid into the plurality of series-connected reaction stages is controlled by the pH value of the reaction stage that is not the first reaction stage. 5 claims
