Characteristics and uses of N-methylpyrrolidone (NMP)

N-methylpyrrolidone ( NMP) is a polar solvent with excellent performance. Because it has very high solubility, high boiling point and low freezing point, it is easy to use and has a wide range of applications.



Features

①NMP is a nitrogen-containing five-membered heterocyclic compound. Because it has the following excellent properties, it has a wide range of applications.

②High polarity, completely miscible In most organic solvents (alcohols, ethers, ketones, aromatic hydrocarbons, chlorinated hydrocarbons, etc.), it is soluble in organic and inorganic substances

③The solution is large. Miscible with water in any proportion.

④Higher flash point than other similar solvents .

⑤Good chemical stability and thermal stability , non-corrosive.


Purpose

NMP can be widely used in the manufacturing of bulk chemicals and fine chemicals.

In recent years, due to the high polarity of NMP, NMP has strong solvent power. Since NMP has the characteristics of high purity and high quality, its use as a high-performance solvent is gradually expanding, mainly in the field of information electronics.
