METHOD FOR PREPARING 3'- AMINOPROPYL-2-SULPHATOETHYLSULPHONE

摘要

(57) In a method for preparing 3'-aminopropyl-2-sulphatoethylsulphone in a one-pot process allyl amine is reacted with mercaptoethanol in dilate sulphuric acid at temperatures of approximately 50 .degree.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 .degree.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.
