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.
This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.

1-Methylimidazole or N-methylimidazole is an aromatic heterocyclic organic compound with the formula CH 3 C 3 H 3 N 2. It is a colourless liquid that is used as a specialty solvent, a base, and as a precursor to some ionic liquids.
N-Vinylpyrrolidone (NVP) is an organic compound consisting of a 5-membered lactam ring linked to a (2 carbon) vinyl group. It is a colorless liquid although commercial samples can appear yellowish. It is produced industrially by vinylation of 2-pyrrolidone, i.e. the base-catalyzed reaction with acetylene. [2]
The amide group can be involved in hydrogen bonding to other nitrogen- and oxygen-containing species.. The predominant solid state form is 2-pyridone. This has been confirmed by X-ray crystallography which shows that the hydrogen in solid state is closer to the nitrogen than to the oxygen (because of the low electron density at the hydrogen the exact positioning is difficult), and IR ...
