| titleOfInvention | Sulphobetain-substituted alpha-sulphonyl carboxylic acids from diallylammonium salts and process for their preparation |
| abstract | The invention relates to new sulfobetaine-substituted α-sulfonylcarboxylic acids of the general formula I and processes for their preparation. As organic intermediates, the compounds of formula I represent a reactive synthesis building block with sulfobetaine character and can be used for further syntheses. In the case of long-chain alkyl radical R 1, polyfunctional surfactants are obtained. According to the invention, molar amounts of diallylammonium chloride are reacted with chloroacetic acid and the double-molar amount of sodium hydrogen sulfite in the presence of a catalytic amount of a peroxodisulfate, and the reaction solution obtained, after addition of a catalytic amount of iodide, is converted by heating to sulfobetaine-substituted α-sulfonylacetic acids according to general formula I. |
