What is the use of NMP?
N-Methylpyrrolidone (NMP) is a solvent used in a variety of industries and applications, such as paint and coating removal, petrochemical processing, engineering plastics coatings, agricultural chemicals, electronic cleaning and industrial/domestic cleaning.
Is NMP stable?
NMP has high chemical and thermal stability and is completely miscible with water at all temperatures.
Is NMP an organic solvent?
N-Methylpyrrolidone (NMP) is a water-miscible organic solvent. NMP increasingly is used as a substitute for chlorinated hydrocarbons. …
Is NMP solvent corrosive?
It is chemically and thermally stable, and not corrosive.
How volatile is NMP?
N-methylpyrrolidone (NMP) is an organic solvent. It is a volatile organic compound (VOC) and has a low vapor pressure of 0.29 mm Hg at 68 F (0.39 mbar at 20 C).
Is NMP a solvent?
NMP (N-Methyl-2-Pyrrolidone) is a polar solvent with outstanding characteristics. It has a wide range of applications because it offers very high solvency, high boiling point, low freezing point, and ease of handling.
What is the pH of NMP?
6.8 to 6.4
Additionally, the pH of NMP under nitrogen-rich conditions remained stable in the range of pH 6.8 to 6.4 for the remainder of the reaction period (Figure 2(c)). Hence, it can be seen that in an oxygen-rich environment the pH of NMP rapidly declines to an acidic pH in a short period of time.
Is NMP a green solvent?
N-Methyl-2-pyrrolidone is a toxic dipolar aprotic solvent widely used in the synthesis of polyurethane dispersions (PUD). Since legislation strongly restricts this substance, green alternatives are essential. Then, polyurethanes dispersible in water need to be modified.
Is NMP polar?
Is NMP flammable?
Hazard Class: 3 (Flammable) 1-Methyl-2-Pyrrolidone is a COMBUSTIBLE LIQUID. Use dry chemical, CO2, water spray or alcohol-resistant foam as extinguishing agents. POISONOUS GASES ARE PRODUCED IN FIRE, including Nitrogen Oxides. Use water spray to keep fire-exposed containers cool.
What kind of solvent is NMP?
What are the dangers of NMP?
Flammable liquids (Category 4) H227 Combustible liquid.
What is NMP chemical?
N-Methylpyrrolidone (NMP) is a solvent used in a variety of industries and applications, such as paint and coating removal, petrochemical processing, engineering plastics coatings, agricultural chemicals, electronic cleaning and industrial/domestic cleaning.
Is ether a nonpolar solvent?
In the context of solvents, polar refers to solvents with higher polarity, and non-polar to solvents with lower polarity. It’s relative. Diethyl ether is at the lower end of the polarity scale and so is generally considered a ‘non-polar’ solvent .
