Cyclization of GABA to 2-pyrrolidone and subsequent methylation of 2-pyrrolidone to NMP was achieved in a one-pot procedure, using methanol as the methylating agent and a halogen salt (i.e. ammonium bromide) as a catalyst. A selectivity above 90% was achieved, as …

Mar 28, 2014 · In this one-pot synthesis method, NMP serves as both dispersing and reducing agent for both the metal precursor and GO, facilitating the formation of monodisperse Pd nanoparticles on RGO...

Nov 22, 2018 · In this study, a green, efficient and low-cost process for the synthesis of N-methylpyrrolidine (NMPD) from 1,4-butanediol (BDO) and methylamine (MA) via a one-pot method was developed. Under the optimized reaction conditions, more than 90% yield of NMPD was achieved over a Cu and Ni modified ZSM-5 catalyst.

N-Methyl-2-pyrrolidone (NMP) is an organic compound consisting of a 5-membered lactam. It is a colorless liquid, although impure samples can appear yellow. It is miscible with water and with most common organic solvents. It also belongs to the class of dipolar aprotic solvents such as dimethylformamide and dimethyl sulfoxide.

Aug 3, 2010 · Cyclization of GABA to 2-pyrrolidone and subsequent methylation of 2-pyrrolidone to NMP was achieved in a one-pot procedure, using methanol as the methylating agent and a halogen salt (i.e....

Dec 10, 2023 · One-pot method for preparing electrode slurry is to combine graphite and PVDF into an NMP solution and mix it well with a high-speed homogenizer. Fig. 3 (a) shows the schematic diagram of the homogenizer device.

GABA can be used as a precursor to produce N-methyl pyrrolidone (NMP) by one-pot cyclization and a methylation reaction [13] (Table 2), which has high chemical and thermal stability making it...

A one-pot method to synthesise NMPD from BDO and MA over Cu-Ni/ZSM-5 was realized by virtue of the borrowing-hydrogen methodology. NMPD could be obtained with high efficiency (92% yield) over a 3%Cu–3%Ni/ZSM-5 catalyst at 300 °C for 6 h under 1 MPa pressure of H 2.

In the present study, we discovered a new N-methyl-2-pyrrolidone (NMP) pretreatment solvent with an excellent lignin solubility and preserved β-O-4 linkages available in the original lignin...

Apr 1, 2019 · N-methyl-2-pyrrolidone (NMP) is a chemical widely used as solvent in several industrial applications. However, many studies and regulations, including REACH, have indicated NMP as a potential toxic agent. Therefore, functional substitutes with …
