| titleOfInvention | Method for producing metal salts of amidosulfonic acid |
| abstract | (57) [Summary] [PROBLEMS] To provide a method for producing a high-quality polyvalent metal salt of amide sulfonic acid having a low content of long-chain fatty acid produced as a by-product. SOLUTION: An alkali metal salt of amide sulfonic acid represented by the general formula (I) is reacted with a water-soluble polyvalent metal salt at pH 8 to 13 in the presence of water, represented by the general formula (II): A method for producing an amidosulfonic acid polyvalent metal salt. Embedded image Embedded image (Wherein, R 1 is a linear or branched alkyl group, alkenyl group or hydroxyalkyl group having 7 to 21 carbon atoms, R 2 is a hydrogen atom or an alkyl group having 1 to 5 carbon atoms, and X is 2 carbon atoms. An alkylene group of 1 to 3, or a compound of the formula A represents an alkali metal atom, M represents a polyvalent metal atom, m represents the valence of M, and n represents an integer of 1 to 4. ) |
