| titleOfInvention | Process for recovering n-methyliminodiacetic acid from sodium sulfate solutions |
| abstract | ABSTRACT N-methyliminodiacetic acid is separated from mixtures of N-methyliminodiacetic acid and sodium sulfate formed by acidification of solutions of its disodium salt with sulfuric acid. Thus the disodium salt is acidified with sulfuric acid to a pH of about 2 and concentrated by evaporating water so as to crystallize sodium sulfate. The sodium sulfate is separated, and the resulting mother liquor is cooled to precipitate N-methyliminodiacetic acid, which is then separated. |
