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.
The sample is then heated to 180 °C to remove solvent residue. In the liquid exfoliation method, first reported by Brent et al. in 2014 [ 7 ] and modified by others, [ 8 ] bulk black phosphorus is first ground in a mortar and pestle and then sonicated in deoxygenated, anhydrous organic liquids such as NMP under an inert atmosphere using low ...
N-Methyl-2-pyrrolidone (NMP) is used as the reaction solvent because it is stable at the high temperatures required for the synthesis and it dissolves both the sulfiding agent and the oligomeric intermediates. Linear, high-molecular-weight PPS that is capable of being extruded into film or melt spun into fiber was invented by Robert W. Campbell ...
It is miscible with water and many organic solvents. [11] Dihydrolevoglucosenone has a boiling point of 226 °C at 101.325 kPa (vs 202 °C for NMP), and a vapor pressure of 12.98 Pa near room temperature (25 °C). [1] It has a comparatively high dynamic viscosity of 14.5 cP (for comparison DMF: 0.92 cP at 20 °C, NMP: 1.67 cP at 25 °C). [12]
