NMP is an extensively used petrochemical solvent owing to its chemical and thermal stability. It serves diverse industries in producing lithium batteries, paint strippers, cleaners, electronics and more. NMP's high velocity, low volatility and toxicity enable wide applicability.
NMP possesses excellent chemical and thermal stability while being fully miscible across all temperatures with water. It can co-solvate with water, alcohols, glycol ethers, ketones and aromatic/chlorinated hydrocarbons. NMP is readily recyclable by distillation and biodegradable.
NMP (N-Methyl-2-pyrrolidone) is a highly polar solvent with remarkable properties including superb solvency, high boiling point, low freezing point and easy handling. This versatility allows extensive industrial utilization.
Studies show NMP in solution starts evaporating around 50°C, well below its ~204°C boiling point. Nearly all NMP evaporates by 180°C, with over 90% disappearing within 100-170°C, elucidating its evaporation behavior.
Recommended NMP drying methods include stirring over CaH2 for 12 hours, distillation at its non-azeotropic 202°C boiling point, and storage over 4 angstrom molecular sieves. These effectively remove water contamination.
Workplace NMP exposure regulations were instituted in 2018, restricting manufacture, use and sale of products containing >0.3% NMP unless specific conditions are satisfied. The restrictions became effective in May 2020.
TOU (2,5,7,10-Tetraoxaundecane) makes an optimal NMP replacement with comparable boiling point, flash point and viscosity but lower surface tension. It demonstrates excellent solvency for diverse polymers and rubbers.
NMP is an extensively utilized solvent in paint/coating removal, petrochemicals, plastics, agrichemicals, electronics and industrial/domestic cleaning owing to its solvency strength.
NMP dissolves numerous coatings including acrylates, epoxies, polyurethanes, PVC, wire enamels, water-based coatings and printing inks, plus varnishes, lacquers and burnt-on carbon.
NMP is a clear, colorless liquid with a fish-like odor, denser than water. It exhibits a 199°F flash point and can irritate skin, eyes and mucous membranes upon contact.
