Process for recovering amide compounds |
| abstract |
There is provided a method for efficiently recovering amide-based compounds such as N-methyl-2-pyrrolidone from a waste liquid containing amide-based compounds such as N-methyl-2-pyrrolidone generated, for example, in a production process of polyarylene sulfide. |
