| titleOfInvention | Method for producing malic acid monoamides and detergent composition containing malic acid monoamides |
| abstract | (57) [Summary] [PROBLEMS] To provide a method for producing malic acid monoamides, By adding an organic solvent to a malic acid and a primary amine or a secondary amine and performing an amidation reaction at 60 ° C. or lower, Produce long-term stable malic acid monoamides with high purity. SOLUTION: A four-necked flask is charged with 158.1 g of acetylmalic anhydride and 340.0 g of acetic acid, and the temperature is set to 40. ° C, and 185.3 g of dodecylamine was added dropwise thereto. The amidation reaction is performed for 3 hours. Then at 70 ° C under reduced pressure for about 2 After distilling off 50.0 g of acetic acid, 48% KOH 0 g is added, and a neutralization reaction is performed at 70 ° C. for 1 hour, and at the same time, deacetylation of acetylmalic acid amide is performed. 700.0 g of 18% hydrochloric acid was added to this salt solution to acid-decompose potassium malate amide, and the reaction solution was filtered to obtain 295.0 g. To obtain mono-N-lauryl malic acid amide. |
