Frequently Asked Questions
What is the primary use of N-Methyl-2-Pyrrolidone?
The primary industrial use of N-Methyl-2-Pyrrolidone (NMP solvent) is as a powerful, highly selective polar solvent. It is widely used in lithium-ion battery manufacturing, photoresist stripping in electronics processing, industrial cleaning, petrochemical extraction, polymer synthesis, and as an ingredient in agrochemical formulations.
What is the molecular weight, chemical formula, and abbreviation of N-Methyl-2-Pyrrolidone?
The chemical formula for N-Methyl-2-Pyrrolidone is C5H9NO, and it is universally known by its abbreviation NMP. Its molecular weight (or molar mass) is approximately 99.13 g/mol. Comprehensive data profiles are also available under its N-Methyl-2-Pyrrolidone PubChem entry.
What is the N-Methyl-2-Pyrrolidone NMP CAS No and flash point?
The official N-Methyl-2-Pyrrolidone NMP CAS no is 872-50-4. The N-Methyl-2-Pyrrolidone flash point is approximately 91 °C (196 °F), making it a stable combustible liquid that requires standard controlled storage conditions.
What is the density of N-Methyl-2-Pyrrolidone and its key physical properties?
Key physical properties of high-purity N-Methyl-2-Pyrrolidone include a boiling point of 202 °C and a density of N-Methyl-2-Pyrrolidone of about 1.028 g/mL at 25 °C. It possesses a clear, colorless liquid appearance with a mild amine odor.
What are the key N-Methyl-2-Pyrrolidone hazards and health effects?
N-Methyl-2-Pyrrolidone hazards include skin, eye, and respiratory irritation. Long-term health effects are monitored because NMP is listed by authorities like ECHA as a substance of very high concern (SVHC) due to reproductive toxicity risk. Strict exposure limits, appropriate engineering controls, and suitable personal protective equipment (PPE) must always be applied during handling.
How is N-Methyl-2-Pyrrolidone produced or synthesized industrially?
Industrial N-Methyl-2-Pyrrolidone production or synthesis is carried out through the reaction of gamma-butyrolactone (GBL) with anhydrous methylamine under high pressure and temperature. This specialized synthesis of N-Methyl-2-Pyrrolidone yields high-purity NMP ideal for critical electronic applications.
Is there a safer N-Methyl-2-Pyrrolidone alternative available?
Depending on the cleaning or formulation process, an N-Methyl-2-Pyrrolidone alternative might include alternative high-boiling polar solvents such as dimethyl sulfoxide (DMSO), ethyl lactate, or propylene carbonate, particularly in systems where strict environmental and health regulations limit NMP usage.
