Method for preparing 3'-aminopropyl-2-sulphatoethylsulphone |
| abstract |
In a method for preparing 3'-aminopropyl-2-sulphatoethylsulphone in a one-pot process, allyl amine is reacted with mercaptoethanol in dilute sulphuric acid at temperatures of approximately 50 °C up to 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 of the elements as an oxidation catalyst, at temperatures of approximately 70 to 100 °C and evaporated to dryness after addition of sufficient sulphuric acid to bring the total sulphuric acid content of the mixture to at least 1 mol, referred to the quantity of allyl amine used. |
