Main product
Technical characteristics and application of N-Methyl-2-pyrrolidone (NMP) NMP is a five-membered nitrogen-containing heterocyclic compound, which has become a key solvent in the industrial field due to its unique physicochemical properties: Core characteristic Excellent solubility 1.1 Strong polar aprotic solvent, completely miscible with alcohol, ether, ketone, aromatic hydrocarbon, and other organic solvents 1.2 High solubility to unsaturated hydrocarbons, aromatics, resins, and inorganic salts (e.g. LiPF₆) Thermodynamic stability 2.1 High boiling point (204℃) and low freezing point (-24℃), suitable for a wide temperature range 2.2 Flashpoint up to 95℃ (closed cup), safety is better than DMF/DMSO and other polar solvents Operational safety 3.1 Strong chemical inertness, non-corrosive to metal 3.2 >99% by vacuum vacuum distillation (according to ISO 14040) Environmental compatibility 4.1 Biodegradable (OECD 301B test degradation rate >60%) 4.2 Comply with REACH Annex XVII and EPA 40 CFR Part 721 |
