The Low Viscosity Advantage of 1-Methyl-2-Pyrrolidone

1-Methyl-2-pyrrolidone, also known as N-Methyl-2-pyrrolidone (NMp), is a polar, low-viscosity liquid with a high boiling point. It is miscible

With water at all temperatures and has good chemical and thermal stability. NMp has good solvency for a wide range of organic and inorganic compounds and is colorless, low toxicity, and has good biocompatibility.

NMp has a dynamic viscosity of 1.661 mpa.s at 25 °C (77 °F). It has a density of 1.033 g/cm3 (20 C), a surface tension of 40.7 g/s2, and a critical temperature of 451°C.

NMp is used in many applications, including:

  • Electronics
  • Metal cleaning
  • Extract agent
  • Synthetic resin surface coating solvent
  • Reaction solvents
  • Equipment washing
  • Plastic lens manufacturing equipment cleaning
  • Pharmaceutical and agricultural chemicals

NMp is hygroscopic and a strong degreaser. It undergoes a hydrolysis reaction in an acidic environment with water to generate 4-methylaminobutyric acid, which is further decomposed into succinic acid semiamide. When NMp encounters air and water during use, it is prone to a decomposition reaction.

N-Methyl-2-Pyrrolidone (NMp): A Versatile And Environmentally-Friendly Solven

N-Methyl-2-pyrrolidone (NMp) is a colorless, low-viscosity solvent with a high boiling point, low toxicity, and good biocompatibility. It is miscible with water and most common organic solvents and is a member of the class of dipolar aprotic solvents such as dimethyl sulfoxide and dimethylformamide. NMp is also biodegradable, odorless, and resistant to chemical and thermal attacks.

NMp is used in the petrochemical, polymer, and battery industries as a solvent, exploiting its nonvolatility and ability to dissolve diverse materials. It is also used in chemical processing, paint thinners, and pharmaceutical applications. NMp's high polarity and high solvency power enable it to dissolve organic and inorganic compounds equally well or better than chlorofluorocarbon solvents. NMp is replacing 1,1,1-trichloroethane in metal cleaning applications due to the worldwide environmental pollution problems associated with chlorinated solvents.

NMp has a mild, fishy odor. It significantly decomposes when heated to a temperature at or above about 700° F. The presence of water has a significant effect on the solvent properties of NMp, particularly on its selectivity and efficiency in several processes.

Is 1-Methyl-2-Pyrrolidone Soluble in Water?

A 5-membered lactam makes up the chemical molecule N-Methyl-2-pyrrolidone (NMP). Even though impure samples can appear yellow, it is a colorless liquid. With water and the majority of typical organic solvents, it is miscible.

What Does NMP Solvent Drying Entail?

Positive electrode N-methylpyrrolidone (NMP) solvent has a boiling point as high as 204°C compared to graphite negative electrode solvent's 90–150°C drying temperature range [5, 6, 7].

Which Distillation Technique Is Better Suited to Distinguish Methanol from Ethanol?

Distillation is a better suggested method for methanol purification since the methanol dehydration process has a much lower separation factor value than ethanol dehydration.Nov. 16, 2020

Does Solubility Depend on The Type of Solvent?

Solutes often dissolve better in solvents that share the most molecular similarities, such as polar solutes in polar solvents and nonpolar solutes in nonpolar solvents. Additionally, if the solute's molecules are smaller than those of the solvent, the solute will be more soluble.

What Elements Affect A Drug's Solubility?

Drug solubility is influenced by the fluid's pH, temperature, volume, and constituents. A drug's lipophilicity and water solubility are connected. Food has the potential to change the rate and scope of absorption.

What Are The Ten Variables That Determine Solubility?

What Use Does The Methylcellulose Excipient Serve?

Methylcellulose is employed as a tablet binder, a viscosity-increasing agent, and a tablet and capsule disintegrant. It is a transparent gel that forms as it dissolves in cold water from a free-flowing white powder. The food, cosmetics, and pharmaceutical industries all use it.

What Function Does Methylcellulose Serve As An Excipient for?

Methylcellulose is widely utilized as an excipient, food ingredient, and formulation assistance for products administered by the oral, topical, and parenteral routes in the pharmaceutical, cosmetic, and food industries.

I read a little about ulcerative colitis. I picked zinc L-carnosine because it was suggested that it could aid in the development of the mucosal lining. I was already familiar with the brand. Most doctors treat Colitis using antibiotics, steroids, and biologics. While that is good for symptom relief, it doesn't tell you WHY the inflammation began. Instead of taking medication, I purchased a *GImap*, which tests for bacteria, fungus, yeast, and other organisms as well as signs of inflammation and intestinal permeability. It is AMAZING. I heartily endorse it. My test results revealed that I had acquired H Pylori, and my calprotectin marker was HIGH. I started the 5R procedure, which is composed of the following steps: remove, replace, reinoculate, repair, and rebalance (number 6 is to REJOICE when it...

I experienced so much acid reflux that I was unable to enumerate every issue it brought about. I used Nexium for about a year until it wasn't enough, at which point I switched to taking two pills a day for a few more years (during which time I still experienced persistent nausea and gas). I was advised to have surgery because my LES was (and possibly still is) pretty much wide open, but I thought it was foolish to go through with it when no doctor could figure out what was causing my acid reflux in the first place! My life was a misery due to acid reflux. I saw an integrative doctor and changed my diet to include more whole, organic foods and less processed foods; I also stopped using a wedge pillow when I slept, lost weight, practiced yoga, worked out several times a week, got tested for specific food allergies, had my DNA tested; took high-level probiotics (50–80 billion) and other supplements to help heal my intestines. In addition, I had 24 IV chelation treatments (not for the heavy metals) and was tested for them.

I don't usually write reviews, but I felt compelled to talk about my experience with this resin. I will now always use it for resin! I am astounded by the lack of bubbles and the mild odor. After curing, there is no tackiness, no dimpling, and no white film. The sheen is better. It seemed to cure sooner than all the other ones I had been using, and I had plenty of work time. My surrounding work space remained cleaner since I noticed that I was dripping less. I finished my assignment late last night, and by this morning at seven o'clock, they had fully recovered. From now on, this will be my only justification for purchases! My typical procedure is to clean my campus, coat everything in multiple coats of mod podge, and wait for it to completely dry before applying resin. I take precise measurements and utilize the container designated for one-to-one ratio boring. Using a drill equipped with a silicone string paddle—which is reasonably priced—is what I've discovered. ZOLSEM has also had a significant impact on the caliber of my argumentation. I usually work on multiple items at once.
