Title: Process for the production of aminosulphonic acids
IPC: C07C309/14
Filed: 1953-05-29
Abstract: A process for the production of an amino alkane sulphonic acid comprises treating an alkylamine hydrochloride with gaseous sulphur dioxide and gaseous chlorine in the presence of a chlorinated hydrocarbon and whilst irradiating the reaction mixture with actinic light, and thereafter subjecting the product obtained to hydrolysis. A gaseous mixture of sulphur dioxide and chlorine may be employed for the sulphochlorination and the alkylamine hydrochloride may be treated in solution or suspension in a chlorinated hydrocarbon, e.g. carbon tetrachloride.  The hydrolysis may be effected by boiling the reaction mixture, freed from chlorohydrocarbons and sulphuryl chloride, with water and evaporating the hydrochloric acid formed in the hydrolysis and precipitating the amine sulphonic acid with anhydrous alcohol.  Products mentioned include 5-amino-pentanesulphonic acid, 6-amino-sulphonic acid and 12 - amino - dodecane - amino - pentylamine, n - hexylamine and n - dodecylamine respectively.  Small amounts of amino-sulphonic acids having the same number of carbon atoms in the molecule and chlorinated in the carbon chain are present in the crude products. In examples 5-amino-pentane sulphonic acid is obtained by blowing hydrogen chloride through a carbon tetrachloride solution of n-pentylamine in a tubular reactor to form the hydrochloride, cooling the product, passing gaseous chlorine and sulphur dioxide through the warm liquid which is irradiated with a mercury vapour lamp, allowing the reaction products to separate into two layers, removing the upper layer and heating it with distilled water, removing hydrochloric acid under vacuum and recrystallizing the dried product from absolute alcohol (1) and (2); 6-amino-hexane-sulphonic acid is obtained in a similar process (3) and in processes similar except that a gas mixture containing chlorine and sulphur dioxide is employed in the sulphochlorination 12-amino-decane-sulphonic acid and 4-amino-butane sulphonic acid are prepared from n-dodecylamine and n-butylamine respectively (4) and (5).
