Title
(EN) METHOD OF PRODUCING TERTIARY AMINE-SULPHUR TRIOXIDE COMPLEXES
(FR) PROCEDE DE PRODUCTION DE COMPLEXES AMINE TERTIAIRE/ANHYDRIDE SULFURIQUE
Abstract
(EN)
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.
(FR)
Dans le procédé décrit, qui sert à produire des complexes amine tertiaire/anhydride sulfurique, représentés par la formule générale: R3N:SO3, où R représente un groupe méthyle, éthyle ou propyle ou une fraction d'une chaîne fermée hétérocyclique renfermée dans de la pyridine, de l'acide chlorosulfonique est ajouté pour dissoudre une amine tertiaire dans un solvant organique chloré. Pour extraire l'amine de l'hydrochlorure d'amine s'étant préalablement formé comme sous-produit, de l'ammoniac gazeux est acheminé dans le mélange de réaction. Cette mesure permet d'augmenter considérablement les rendements du procédé. Du chlorure d'amonium se forme comme sous-produit.
