Is NMP toxic?
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 polar solvent?
NMP (N-Methyl-2-Pyrrolidone) is a polar solvent with outstanding characteristics. It has a wide range of applications because it offers very high solvency, high boiling point, low freezing point, and ease of handling.
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.
How do you make methyl 2 pyrrolidone?
N-Methyl-2-pyrrolidone (NMP) is prepared by preparing a mixture comprising monomethylamine, dimethylamine and trimethylamine and ammonia in a first process step by reacting ammonia with methanol at elevated temperature in the presence of a catalyst, separating 10 off the ammonia, reacting the mixture comprising the …
