Abstract: The invention relates to a method for continuously producing hydroxylammonium 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.

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.

Abstract: Zpusob kontinuální výroby hydroxylamonných solí katalytickou redukcí oxidu dusnatého s vodíkem ve zredeném vodnatém roztoku minerální soli ve více za sebou zarazených reakcních stupních spocívá v tom, že prítok zredeného vodnatého roztoku minerální kyseliny se pred prívodem do více za sebou zarazených reakcních stupnu rozdelí na alespon dva dílcí proudy, první z uvedených dílcích proudu se zavede do prvního reakcního stupne, druhý z uvedených dílcích proudu se zavede do jiného než prvního reakcního stupne, pricemž se prítok zredeného vodného roztoku minerální kyseliny do více za sebou zarazených reakcních stupnu rídí pomocí hodnoty pH tohoto jiného než prvního reakcního stupne.

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
