N-methyl-2-pyrrolidone

N-Methyl-2-pyrrolidone (NMP) is a powerful solvent with a high boiling point. It is colorless and has a slight amine odor. NMP is miscible with water and most organic solvents, making it a versatile medium for the dissolution of a wide range of substances. It is used in a variety of industrial applications, including the production of polymers and resins, and in the electronics industry for the production of semiconductors.

Chemical Properties[edit | edit source]

NMP is a polar aprotic solvent that has the ability to dissolve a wide range of polymers. It is chemically stable and has a high boiling point of 202°C. Its chemical formula is C5H9NO. The compound is also fully miscible with water, alcohols, and almost all organic solvents.

Uses[edit | edit source]

NMP is used in a variety of industrial applications. It is used in the production of polymers like polyvinyl chloride (PVC), polyurethane (PU), and polyacrylonitrile (PAN). It is also used in the electronics industry for the production of semiconductors, and in the pharmaceutical industry for the production of certain drugs.

Health Effects[edit | edit source]

Exposure to NMP can cause irritation to the eyes, skin, and respiratory tract. It can also cause nausea, headache, and in severe cases, damage to the liver and kidneys. Therefore, it is important to handle NMP with care and use appropriate protective equipment.

Regulation[edit | edit source]

Due to its potential health effects, the use of NMP is regulated in many countries. In the European Union, for example, it is classified as a Substance of Very High Concern (SVHC) under the REACH regulation.
