N-Methyl-2-Pyrrolidone also named 1-Methyl-2pyrrolidone is a powerful polar solvent with good chemical stability and broad solubility for resins and high chemical and thermal stability.NMP is completely soluble with water at all temperatures and is soluble with most organic solvents.These characteristics of the N-Methyl-2-Pyrrolidone are highly useful in a variety of chemical reactions where an inert medium is of concern.Despite the stability of NMP, it can also play an active role in a certain reactions:hydrolysis,oxidation,condensation,conversion with chlorinating agents,polymerization and o-alkylation’s,and related reactions.
