Does NMP react with water?

Does NMP react with water?

N-Methyl-2-pyrrolidone (NMP) is an organic compound consisting of a 5-membered lactam. It is a colorless liquid, although impure samples can appear yellow. It is miscible with water and with most common organic solvents.

Does NMP dissolve in water?

Product description. N-Methyl-2-Pyrrolidone (NMP) is a high boiling, polar aprotic, low viscosity liquid. NMP has a good solvency for a wide range of organic and inorganic compounds and it is miscible with water at all temperatures and has a high chemical and thermal stability.

Is NMP acidic or basic?

NMP is stable under neutral conditions, but it is easy to open loop under acidic or alkaline conditions to form acid and other products, and both alkali and temperature have effects on the hydrolysis of NMP[9].

What is N methyl pyrrolidone used for?

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 N-methyl-2-pyrrolidone polar?

Introduction. N-Methyl-2-pyrrolidone (NMP), C5H9NO, is a strongly polar (μ = 4.09 D) (1) aprotic solvent that is a liquid at room temperature. NMP (Figure 1) exhibits a unique combination of physicochemical properties that have led to its frequent use as a solvent in a range of industrial applications.

Is N methyl 2 pyrrolidone corrosive?

It is chemically and thermally stable, and not corrosive.

Is N methyl 2 pyrrolidone hazardous?

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.

Is NMP a ketone?

Category: Ketone.

What type of solvent is DMF?

aprotic solvent
DMF is a polar (hydrophilic) aprotic solvent with a high boiling point. It facilitates reactions that follow polar mechanisms, such as SN2 reactions.

Is there a microwave assisted synthesis of N-methyl pyrrolidone?

What does N-methyl 2 pyrrolidone look like?

N-methyl-2-pyrrolidone appears as a clear colorless liquid with a “fishlike” odor. Denser than water. Flash point 199°F. Contact may irritate skin, eyes and mucous membranes. May be toxic by ingestion.

How is NMP/N-methyl-2-pyrrolidone made?

Large-scale production of NMP /N-methyl-2-pyrrolidone/ is predominantly carried out by reacting gamma-butyrolactone with an excess of pure or aqueous methylamine in a high-pressure tube reactor (6-12 MPa). The reaction is exothermic and often run under adiabatic conditions with reactor temperatures in the range of 250-400 °C.
