N-Cyclohexyl-2-pyrrolidone Chemical Properties,Usage,Production
Uses
N-Cyclohexylpyrrolidone possesses excellent properties such as high boiling point, high solubility, and improved fabric leveling, and is safe and non-toxic to humans. Due to its superior performance, N-cyclohexylpyrrolidone products are widely used in fabric leveling agents, polymer solvents, and ink dispersants. Currently, N-cyclohexylpyrrolidone exhibits excellent leveling and dispersibility, strong solubility for polymers (especially polyimide compounds, mainly used as encapsulants for mobile phone screen protectors and high-speed rail motors), and can be used as a solvent during polymerization.
Chemical Properties
clear liquid
Safety Profile
Poison by ingestion. Moderately toxic by inhalation and slun contact. A severe skin and eye irritant. When heated to decomposition it emits toxic fumes of NOx.
Synthesis
1307661-20-6
6837-24-7
Bis[(4-chlorophenyl)methyl](4-chloro-3-butynyl)amine (5) (31.8 mg, 0.090 mmol) was used as a raw material and reacted with rhodium trifluoroacetate dimer (Rh2(tfa)4, 1.18 mg, 0.018 mmol) under argon protection in a mixed solvent of toluene (1.0 mL) and water (0.01 mL) at a heated reflux for 10 hr. After the reaction was completed, the mixture was cooled down. After completion of the reaction, the mixture was cooled to room temperature and filtered through a short diatomaceous earth pad assisted with ethyl acetate. The filtrates were combined and concentrated under reduced pressure to obtain the crude product. The crude product was purified by silica gel column chromatography (eluent: hexane-ethyl acetate mixed solvent) to give N-cyclohexylpyrrolidone (15.5 mg, 82% yield) as a final oil. The structure of the product was confirmed by 1H NMR, 13C NMR and IR: 1H NMR (δ, ppm): 2.01 (quintuple peak, J = 7.7 Hz, 2H), 2.45 (t, J = 7.7 Hz, 2H), 3.26 (t, J = 7.7 Hz, 2H), 4.42 (s, 2H), 7.18 (d, J = 8.4 Hz, 2H), 7.30 ( d, J = 8.4 Hz, 2H); 13C NMR (δ, ppm): 17.78, 30.81, 46.02, 66.60, 128.87 (2C), 129.51 (2C), 133.51, 135.22, 174.97; IR (pure, cm-1): 3060, 3049, 2926, 1682 (C=O) , 1493, 1093, 1016, 802.
