(57) Abstract In a method for preparing 3'-aminopropyl-2-sulphatoethylsulphone in a one-pot process allyl amine is reacted with mer- captoethanol in dilate sulphuric acid at temperatures of approximately 50 °C up so the boiling point in the presence of a radical starter. The resultant reaction mixture is oxidized with hydrogen peroxide in the presence of catalytic quantities of a compound of a transition metal of the periodic system or the elements as an oxidation catalyst at temperatures of approximately 70 to 100 °C and evaporated to dryness after addition or sufficient sulphuric acid to bring the total sulphuric acid content of the mixture to at least 1 mol, referred to the quantity or allyl amine used.
