METHOD AND DEVICE FOR THE PREPARATION OF LEUCOINDIGO SALT SOLUTIONS EXEMPTED FROM ANILINE |
| abstract |
The invention relates to a process for the preparation of an aniline-free or aniline-free aqueous solution of leucoindigo free of N-methylaniline from an aqueous solution of leucoindigo comprising aniline or aniline and N-methylaniline, the concentration of aniline or aniline and N-methylaniline being determined according to ISO 14362-1: 2017 (E), said leucoindigo being in the form of an alkali metal salt, the process comprising at least steps (A) to (C) comprising: (A) using a liquid stream comprising said aqueous leucoindigo solution comprising said one or more amines; (B) use a purification flow; (C) contacting said stream of liquid with said purification stream. |
