N-Methyl-2-pyrrolidone (NMP) is an organic compound consisting of a 5-membered lactam. It is a colorless liquid, although impure samples can appear yellow. It is miscible with water and with most common organic solvents. It also belongs to the class of dipolar aprotic solvents such as dimethylformamide and dimethyl sulfoxide.
2-Pyrrolidone itself is used in inkjet cartridges. [5] A variety of pharmaceutical drugs are 2-pyrrolidone derivatives, including cotinine, doxapram, povidone, and ethosuximide, and the racetams. The chemical is an intermediate in the production of the polyvinylpyrrolidone precursor vinylpyrrolidone. [3]
Pyrrolidine, also known as tetrahydropyrrole, is an organic compound with the molecular formula (CH 2) 4 NH. It is a cyclic secondary amine , also classified as a saturated heterocycle . It is a colourless liquid that is miscible with water and most organic solvents.
Racetams are 2-pyrrolidone derivatives and may sometimes be referred to simply as pyrrolidones (2-oxopyrrolidines). [1] Many, but not all, specifically have a 2-oxo-1-pyrrolidine acetamide nucleus, which is the chemical structure of piracetam. Racetams are cyclic derivatives of the inhibitory neurotransmitter γ-aminobutyric acid (GABA). [2]
Solution of PVDF 1−2% by mass in N-methyl-2-pyrrolidone (NMP) is mixed with an active lithium storage material such as graphite, silicon, tin, LiCoO 2, LiMn 2 O 4, or LiFePO 4 and a conductive additive such as carbon black or carbon nanofibers.

Most of those methods, but not all, involve the use of a solvent either for liquid-liquid extraction or extractive distillation. Many different solvents are suitable, including sulfolane (C 4 H 8 O 2 S), furfural (C 5 H 4 O 2 ), tetraethylene glycol (C 8 H 18 O 5 ), dimethylsulfoxide (C 2 H 6 OS), and N-methyl-2-pyrrolidone (C 5 H 9 NO).
