Exploring The Properties And Uses of N-Methyl-2-Pyrrolidone: A Non-Corrosive Solvent

1-Methyl-2-pyrrolidone (NMp) is a non-corrosive, polar organic solvent that is chemically and thermally stable. It is a colorless liquid with a high boiling point and a strong affinity for HS and CO. NMp is miscible with water and most common organic solvents, and it belongs to the class of dipolar aprotic solvents such as dimethylformamide and dimethyl sulfoxide.

NMp is used in a variety of industries and applications, including:

  • paint and coating removal
  • petrochemical processing
  • Engineering plastics coatings
  • Agricultural chemicals
  • Electronic cleaning
  • Industrial/domestic cleaning
  • Semiconductor industry: As a degreaser, resist stripper, and solvent for phenolic die coat resins
  • Fluorinated coatings: As a solvent for dissolving binder resins, such as polyamide/imide (pAI) or polyethersulfone (PES)

NMp is chemically inactive and non-corrosive to other metals such as carbon steel and aluminum, except for copper.

NMp is a combustible liquid that produces poisonous gases in fire, including nitrogen oxides. Use dry chemicals, CO2, water spray, or alcohol-resistant foam as extinguishing agents. Vapors may travel to a source of ignition and flash back. Vapor is heavier than air and may travel a distance to cause a fire or explosion far from the source.

N-Methyl-2-Pyrrolidone (NMp): A Versatile Solvent with Potential Health Risks

1-Methyl-2-pyrrolidone (NMp) is chemically inactive and non-corrosive to metals such as carbon steel and aluminum, except for copper. It is miscible with water and most common organic solvents. NMp is also a dipolar aprotic solvent, like dimethyl sulfoxide and dimethylformamide.

NMp is used in the petrochemical, polymer, and battery industries as a solvent because of its nonvolatility and ability to dissolve various materials. It is also used to produce fine chemicals from mass-produced chemicals and in the electronics field. NMp can dissolve organic and inorganic compounds equally well or better than chlorofluorocarbon solvents.

NMp is toxic to the reproductive system of male and female test animals and harms the developing fetus when tested in pregnant animals. Based on the animal tests, NMp should be treated as a potential human reproductive hazard.

NMp decomposes on heating and burning, producing toxic fumes including nitrogen oxides and carbon monoxide. Vapor is heavier than air and may travel a distance to cause a fire or explosion far from the source. NMp is not compatible with oxidizing agents, strong acids, reducing agents, and strong bases.

I purchased this for a five-year-old child who enjoys building large Lego sets and tinkering with things in general and science in particular. He does, I believe, benefit from having a good attention span for a 5-year-old when it comes to toys of this kind. Regarding the toy itself, it is of the same excellent quality as other Osmo products; the only problem is keeping the toy pieces from becoming lost. About the games, before I "had" to take the course and learn how to code, I was a college engineering major with no prior coding experience. There aren't too many ways to expose young children who are interested in science, but I really believe it's a terrific concept. The child for whom I purchased this recently had his STEM coding summer camp canceled because of COVID-19. I truly value this product's objective.


This device truly is incredible. I enjoy mixing drinks for friends and myself and consider myself somewhat of an alcoholic. I can spend weeks without mixing a cocktail with freshly squeezed juice, so I don't really want to take the effort to pick up mixers and fruit now that my workload at work has risen and I'm getting home later. Before I can consume it all, the fruit spoils. I have so continued to drink my typical bourbon neat. This device is invaluable. I sampled the Long Island tea, and it was excellent at regular strength. I made my wife some beachside sex because she prefers a lighter drink. Additionally ideal. It's the greatest option if you can purchase the pods and have the necessary funds. I will amend the review if it begins to malfunction. Update, December 2: I've had the old fashioned and margarita now. Wow. Although it wasn't as tart as using fresh limes, the margarita wasn't overly sugary like the cheap mixers at the grocery store, and it was still the greatest margarita I've ever experienced.


I'm always cautious about the items I try, especially on my face, because I have really sensitive skin. Products that feel excessively greasy, are tested on animals, or contain odd compounds don't appeal to me. Fortunately, despite the eczema on my arms, neck, and legs, my face has typically remained clear. I want to look like I'm in my 20s even though I'm in my early 30s, so I never really established a regimen until recently. After looking at a tonne of goods for months, reading research and articles, and hearing dermatologists' opinions, I've come to the conclusion that a basic skin care regimen shouldn't need twelve steps or incredibly expensive items—that is, unless they are effective for you. Although I'm by no means an authority on the topic, your skin should be treated carefully; excessive use of harsh products is not necessary. Having said that, I have always relied on the CeraVe brand to treat my eczema flare-ups, and I'm glad to have discovered this wonderful vitamin C serum. In the morning, I utilize it.
