N-methyl pyrrolidone (NMP) is a polar aprotic solvent that is critical for the production of polyaramids. However, due to its reprotoxicity and pending REACH restrictions, a benign alternative is needed. A mixture of N-butyl pyrrolidone (NBP) and the ionic liquid [C₈MIm][Cl] is proposed as a promising candidate to replace NMP. This organic electrolyte solution provides a green approach to polyaramid synthesis.

N-丁基吡咯烷酮/离子液体混合物作为用于合成聚芳酰胺的 N-甲基吡咯烷酮的良性替代溶剂

N-甲基吡咯烷酮 (NMP) 是一种极性非质子溶剂，对生产聚芳酰胺至关重要。然而，由于其生殖毒性和未决的 REACH 限制，需要一种良性的替代品。的混合物Ñ（NBP）的离子液体[C丁基吡咯烷酮和₈ MIM] [CL]被提议为有希望的候选替换NMP。这种有机电解质溶液为聚芳酰胺合成提供了一种绿色方法。
