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.
Polyamide-imide resin is hygroscopic, and picks up ambient moisture. Before processing the resin, drying is required to avoid brittle parts, foaming, and other molding problems. The resin must be dried to a moisture content of 500 ppm or less. A desiccant dryer capable of maintaining a dew point of −40 °F (−40 °C) is recommended. If ...
Metadoxine, also known as pyridoxine-pyrrolidone carboxylate, is a drug used to treat chronic and acute alcohol intoxication. [1] Metadoxine accelerates alcohol clearance from the blood. [2] Metadoxine is an ion pair salt of pyridoxine and pyrrolidone carboxylate (PCA). [1]
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]
2-Pyrrolidone, also known as 2-pyrrolidinone or butyrolactam, is an organic compound consisting of a 5-membered lactam, making it the simplest γ-lactam. It is a colorless liquid that is miscible with water and most common organic solvents.
Production of PPTA relies on a co-solvent with an ionic component (calcium chloride, CaCl 2) to occupy the hydrogen bonds of the amide groups, and an organic component (N-methyl pyrrolidone, NMP) to dissolve the aromatic polymer. This process was invented by Leo Vollbracht at Akzo.
