<p>In the present method of producing tertiary amine-sulphur trioxide complexes of the general formula: R3N:SO3, where R is a methyl, ethyl, or propyl group or a moiety of a heterocyclic ring in pyridine, chlorosulfonic acid is added to dissolve a tertiary amine in a chlorinated organic solvent. To recover amine from amine hydrochloride previously formed as by-product, gaseous ammonia is passed into the reaction mixture. This measure makes it possible to increase the yields considerably. Ammonium chloride is formed as by-product.</p> |
