PROCESS FOR THE SEPARATION OF LONG CHAIN AMINO ACIDS AND LONG CHAIN DIBASIC ACIDS |
| abstract |
The invention relates to a method for the separation of long-chain amino acid and long-chain dibasic acid, comprising: (1) recovering an alkylamine contained in an aqueous solution of an alkaline hydroxide hydrolysis of amide derivatives mixed by distillation or by extraction with an extraction agent solvent; (2) cooling the aqueous solution of step (1) to precipitate mixed alkaline salts of long-chain amino acid and long-chain dibasic acid; (3) recovering the mixed alkaline salts of the long-chain amino acid and the long-chain dibasic acid to obtain a mother liquor; (4) separating the long-chain amino acid and the long-chain dibasic acid by acidification-extraction of the long-chain dibasic acid with an extractant solvent or by selective dissolution of an alkaline salt of a long-chain amino acid in an aqueous solvent; and (4) adding an acid to the mother liquor of step (3) to obtain an alkanoic acid. |
