| description | A process is provided for removing at least one contaminant selected from the group consisting of phenol, thiophenol, and phenyl disulfide from contaminated NMP by reacting at least one monohalogenated aromatic compound and a base with the contaminated NMP.
L'invention concerne un procédé d'élimination, à partir de N-méthyl-2-pyrrolidone, d'au moins un contaminant choisi dans les groupe constitué par phénol, thiophénol et disulfure de phényle, ce procédé consistant à faire réagir au moins un composé aromatique monohalogéné, et une base, avec une N-méthyl-2-pyrrolidone contaminée. |
