2025年1月1日 · N-methyl-2-pyrrolidone (NMP) is a typical N-heterocyclic compound, with the advantages of high polarity, low volatility, high water-miscibility, non-corrosiveness, and high chemical and thermal stability, compared with other organic solvents (Ghosh et al., 2006; Yu et al., 2023; Zhao et al., 2021).

2025年2月1日 · The NMP loss rates of the vacuum distillation, PV, and PV-A were 0.746%, 2.98%, and 0.3%, respectively. The NMP loss of vacuum distillation was mainly concentrated in the tower reactor of the refining tower, and a small amount of NMP entered the residual liquid recovery tank with high-boiling-point impurities.

N-methyl-2-pyrrolidone (commonly referred to as NMP or M-Pyrol) is used within the semiconductor industry as a degreaser, a resist stripper and as a solvent for phenolic die coat resins is known to cause skin irritation and to rapidly permeate through intact skin. The U.S. Environmental Protection Agency (EPA) in a final assessment document on ...

2022年7月15日 · The influence of NMP concentration on degradation (Fig. 3) was studied in the concentration range 10–50 mg/L. The concentration of PMS was kept constant at 100 mg/L. At 10 mg/L, the degradation of NMP was 84%; however, with an increase in concentration to 50 mg/L, the removal was decreased to 26%.

2014年4月1日 · Deformation curves of NMP slurries with NMC powder, PVDF binders and carbon black (arrows refer to existing yield points of the slurries). Download: Download full-size image; Fig. 10. Amplitude sweeps of NMP based slurries with NMC powder, PVDF binder and carbon black (angular frequency ω=10 s −1). Download: Download full-size image; Fig. 11.

2024年2月1日 · In the lithium-ion battery industry, n-methyl-2-pyrrolidone (NMP) is widely used as the solvent for cathode slurry, and polyvinylidene fluoride (PVDF) is used as the cathode binder. However, because of the harmful effect of NMP on the environment and human health, the use of NMP and PVDF for lithium-ion batteries will be highly regulated in the ...

2014年5月22日 · NMP’s capacity to combine CRBN-independent immunomodulatory activity with broad-spectrum BRD antagonism provides a unique therapeutic modality with predicted activity in the setting of IMiD-resistant MM. Additional therapeutic benefit may already be evident, because NMP (a potential component of orthopedic cement) was reported to augment bone ...

2012年2月1日 · The NMP–water/oxygen stress conditions do have a few limitations including a large solvent peak in the void when operating below 280 nm, an occasional reaction between NMP or an NMP degradation product (other than the hydroperoxide) and an API, peroxide buildup in old NMP, and inhibited formation of benzylic hydroperoxides when an API also ...

2020年10月1日 · Lithium metal remained stable against NMP solvent and no excessive byproducts formation was observed on the surface for several hours. Although there is a minor chemical reaction between NMP and lithium metal, the NPH-GPE has a satisfactory stability with lithium metal due to the introduction of PVDF-HFP chains and high concentration lithium salt.

The first involves the copper-catalyzed N-arylation of sulfonamide 151 in the presence of 2,2′-bipyridine and K 3 PO 4 in N-methyl-2-pyrrolidone (NMP) at 120 °C. A variety of aryl bromides/iodides and 2-chloro- and 2-bromopyridines react to …
