Properties And Applications of N-Methyl-2-Pyrrolidone (NMp)

N-Methyl-2-pyrrolidone (NMp) is a solvent with high solvency for a wide range of organic and inorganic compounds. It is a colorless, high boiling liquid with a mild amine-like odor, low volatility, and high flash point. NMp is miscible with water at all temperatures and has high chemical and thermal stability.

NMp is used in many industries and applications, including:

  • Paint and coating removal
  • Petrochemical processing
  • Engineering plastics coatings
  • Agricultural chemicals
  • Electronic cleaning
  • Industrial/ domestic cleaning
  • Surface treatment of textiles, resins, and metal-coated plastics

NMp is the product of choice for paint strippers, agricultural chemicals, and process solvent applications due to its solvent power and exceptional performance.

NMp should be handled with specific safety protocols, including:

  • Wearing appropriate personal protective equipment (PPE), including gloves, goggles, and protective clothing, to avoid skin and eye contact
  • Working in well-ventilated areas to minimize inhalation risks
  • Using proper respirators if necessary

NMp can be absorbed into the body by inhalation, through the skin, and by ingestion. Exposure to NMp can cause:

  • Rapid, irregular respiration
  • Shortness of breath
  • Decreased pain reflex
  • Slight bloody nasal secretion
  • Headaches
  • Redness and pain
  • A burning sensation in the throat and chest
  • Acute solvent syndrome

Mechanisms of Action And Applications of N-Methyl-2-Pyrrolidone (NMP)

N-Methyl-2-pyrrolidone (NMp) is a polar solvent with high solvency for a wide range of organic and inorganic compounds. NMp is miscible with water at all temperatures and has high chemical and thermal stability. It has a selective affinity for unsaturated hydrocarbons, aromatics, and sulfur compounds. NMp can serve as a co-solvent with water, aromatic/chlorinated hydrocarbons, alcohols, glycol ethers, and ketones.

NMp is used in various industries and applications, such as:

  • Paint and coating removal
  • Petrochemical processing
  • Engineering plastics coatings
  • Agricultural chemicals
  • Electronic cleaning
  • Industrial/ domestic cleaning
  • Surface treatment of textiles, resins, and metal-coated plastics

NMp is a five-member-ring compound containing nitrogen. It has a high flash point compared to similar solvents, and a high boiling point and low freezing point. NMp is also chemically and thermally stable, and not corrosive.

NMp can be absorbed into the body by inhalation, through the skin, and by ingestion. Exposure to NMp can cause:

  • Rapid, irregular respiration
  • Shortness of breath
  • Decreased pain reflex
  • Slight bloody nasal secretion
  • Headaches
  • Redness and pain on skin
  • A burning sensation in the throat and chest
  • Acute solvent syndrome

Breathing excessive amounts for a short period can cause nausea, dizziness, clumsiness, and drowsiness.

PMMA Is More Durable Than Glass.

PMMA is a robust, durable, and light material. Its density, which is less than half that of glass, ranges between 1.17 and 1.20 g/cm3. Although PMMA's impact strength is higher than that of glass and polystyrene, it is still much less powerful than that of polycarbonate and some synthetic polymers.

Does DMSO Dissolve PDMS?

Other names for this product are Trimethylsiloxy-terminated polydimethylsiloxane (Sylgard 184), silicone, dimethicone, polymerized siloxane, PDMS, and silicone. Most chlorinated, hydrocarbon, or ethereal solvents are soluble. Insoluble in water, glycerol, MeOH, and EtOH. restricted soluble in DMSO and DMF.Sept. 15, 2011

How Harmful Is Methanol for Cancer?

There is no evidence that methanol causes cancer. Methanol exposure may be detrimental to development if it is chronic or repetitive. The possibility of reproductive damage from repeated or chronic exposure to methanol is unknown. Humans who use methanol may experience central nervous system birth abnormalities.

Does Olvent Temperature Have An Impact on Olubility?

More heat is introduced into the system as the temperature rises. By preventing the diolution reaction, the system will respond to this excess heat energy in accordance with Le Chatelier's Principle. Therefore, as the temperature rises, the substance becomes less soluble.

What Shade of Orange Is The NMP?

A 5-membered lactam makes up the chemical molecule N-Methyl-2-pyrrolidone (NMP). Although impure enough, it is a colored liquid that sometimes looks yellow. It is more easily targeted by water and by the most prevalent organic solvent.

What Is The NMP's Water Compatibility?

The water-soluble target N-methyl pyrrolidone (NMP) is an aprotic solvent with a log Kow of 0.54. According to reports (1-4), it increases the solubility and permeability of many drugs. Both parenterally and orally, it has a low level of toxicity (5).

How Are PVDF Binders Made?

PVDF is the primary binder material used in the creation and maintenance of the composite electrode in lithium-ion batteries. A solution of 1% to 2% PVDF is dissolved in a lithium storage substance such graphite, tin, or silicon. A conductive additive, like carbon fiber, was also added.

In What Manner Is N-Methyl-2-Pyrrolidone Made?

N-Methyl-2-pyrrolidone (NMP) is produced by reacting monomethylamine, dimethylamine, trimethylamine, and ammonia with methanol at an elevated temperature in the presence of a catalyst for the first time, then separating out 10% of the ammonia before reacting the mixture with the remaining ingredients.

What Is The Purpose of 2-Pyrrolidone?

The liquid form of 2-pyrrolidone is colorless to yellow and has a light, amine-like smell. It required an oily solvent and an aqueous coating. In floor paint, it served as an etting agent for acrylic emulsion and acrylic/tyrene copolymer. N-vinylpyrrolidone (NVP) is a precursor to 2-pyrrolidone.

Does Methanol Dissolve Methyl Methacrylate?

Introduction. At room temperature, poly(methyl methacrylate, or PMMA), which is soluble in water but not well soluble in methanol, became more soluble in the mixture of water and methanol that contained 80 to 95 weight percent of methanol.

Here is a comparison photo of my front hall before and after. 2.5 sponges and 30 minutes! The procedure: I prayed before wiping the drips off (so they don't turn into their own stains!) with a *MAGIC* sponge in one hand and a dry towel in the other. The Markers, Crayons, Pens, and Dry Erase Are The Stains! Abrasion and van der Waals forces are its mechanisms! I continued to wear gloves since I didn't want the vibrant drips (and possibly some wall paint) to get all over my hands. I was so upset trying to clean comparable walls with soap and water, cleaning supplies, and even stinky stuff like vinegar and isopropyl alcohol! This item truly does wonders! No scent, very quick, actually a...

This is a great purchase for the money, especially with the added benefit of savings from Subscribe and Save. I've frequently purchased these from various places, usually a grocery store, but this method I saved money. These are used to remove paint, stains, or other marks off wood cabinets without causing damage to the wood or finish. Use them to clean the walls, sinks, linoleum floors, appliances, and showers as well. Other than that, I haven't had any problems, and I'm frequently astonished at how much paint they manage to scrub off the walls if it's cheap paint. Even if they remove foreign material, even if it has been there for a while, they do not scratch surfaces. This home was purchased by us in 2015, and there...

I am currently unable to imagine life without this. I use this on my color pencil drawings to give them a more watercolor-painted appearance, although some artists use it for their oil paintings. It, in my opinion, truly allows the color to sink into the pages. ~~~~~~Some observations I would like to make ~~~~~ Use a soft color pencil if you want your color to spread out more like an oil pastel. Although a hard color pencil does merge into the paper, there is less pigment overall. You should also consider whether you need to use a brush for line textures depending on the object you are applying the distilled turpentine on (examples: tables, trees, long hair). Alternatively, use a cotton swab.
