Is N methyl pyrrolidone hazardous?
The European Chemicals Agency classifies NMP as a “Substance of Very High Concern” because of its toxicity to reproduction based on developmental toxicity.
Is NMP corrosive?
It is highly polar and miscible with most organic solvents (alcohols, ethers, ketones, aromatic hydrocarbons, chlorinated hydrocarbons, etc.). Organic and inorganic substances are highly soluble in it. It is chemically and thermally stable, and not corrosive.
What is N-methyl-2-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 NMP a VOC?
NMP is considered a volatile organic compound (VOC) and is a California Prop 65 substance.
What is pyrrolidone used for?
Specifically, it is used as a solvent for surface treatment of textiles, resins, and metal coated plastics or as a paint stripper. It is also used as a solvent in the commercial preparation of polyphenylene sulfide.
Is 2 pyrrolidone a VOC?
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). It is combustible, with a flash point of 199 F (93 C). Many oils become soluble in NMP only when the solvent is above 145 F (63 C).
Does NMP react with water?
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 methyl alcohol a VOC?
It is highly flammable. Methanol is used to dissolve other chemical substances and mixes readily with water and many organic liquids. Methanol is considered a volatile organic compound by the National Pollutant Inventory.

What is the solubility of N-methyl-2-pyrrolidone?
N-Methyl-2-pyrrolidone Version 1.0 Revision Date: 10/27/2014 MSDS Number: 100000004560 8 / 18 N-Methyl-2-pyrrolidone Solubility in other sol-vents : completely miscible Solvent: organic solvents Partition coefficient: n-octanol/water : log Pow: -0.46 @ 25 °C (77 °F) Auto-ignition temperature : 245 °C 760 mmHg Thermal decomposition :
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.
