2-pyrrolidone

[¦tü pə′räl·ə‚dēn]
(organic chemistry)
C4H7ON Combustible, light-yellow liquid, boiling at 245°C; soluble in ethyl alcohol, water, chloroform, and carbon disulfide; used as a plasticizer and polymer solvent, in insecticides and specialty inks, and as a nylon-4 precursor.

Fourier transform infrared spectroscopy was used to investigate the interactions between [C.sub.60] and [C.sub.70] nanoparticles and 2-pyrrolidone (2-pyrrolidinone, [gamma]--lactam) in a toluene solvent environment.

This paper reports the results of an infrared spectroscopic study of the interactions between [C.sub.60] and [C.sub.70] nanoparticles and 2-pyrrolidone using toluene as a solvent environment (Aksenova et al.
The compound 2-pyrrolidone is a five-membered, cyclic amide sometimes referred to as gamma-lactam ([gamma]-lactam) or 2-pyrrolidinone.
Since the 2-pyrrolidone interaction with the nanoparticles is likely an equilibrium process involving both interacting and non-interacting 2-pyrrolidone, spectral collection was carried out over a broad concentration range (200 to 2 microliters ([micro]L) of 2-pyrrolidone per mL of toluene or toluene saturated with the nanoparticles) to determine the optimal concentrations to observe infrared spectral changes.
