Basic Information
Product Name: N-Vinylcaprolactam (NVCL)
CAS No.:2235-00-9
Molecular Formula: C8H18NO
Molecular Weight: 139.19 g/mol
Appearance: Colorless to light yellow liquid or white to light yellow powder.
Odor: Characteristic smell.
Melting Point: 35-38 °C (decomposes).
Boiling Point: 128 °C (21 mmHg) or 254.7 °C (at atmospheric pressure).
Density: 1.029 g/mL at 25 °C (liquid) / 1.05 g/cm³ (solid).
Flash Point: 112.5 °C (closed cup) or 214 °F.
Solubility: Partially soluble in water; soluble in common organic solvents (e.g., ethanol, acetone).
Chemical Properties
Stability: Stable under normal conditions, but flammable. Incompatible with strong oxidizing agents.
Reactivity: Contains a reactive vinyl double bond, enabling various transformations:
Polymerization: Undergoes radical polymerization (initiated by peroxides) to form poly(N-vinylcaprolactam), a temperature-sensitive polymer used in biomedical and smart material applications.
Hydrogenation: Can be hydrogenated to yield saturated derivatives under appropriate conditions.
Applications
Polymer Synthesis: A key monomer for producing thermoresponsive polymers (e.g., poly(N-vinylcaprolactam)), which exhibit lower critical solution temperature (LCST) behavior and find use in:
Biomedical fields (drug delivery systems, tissue engineering).
Smart materials (adhesives, sensors).
Plastics Modification: Improves the flexibility and toughness of polymers like PP, ABS, and PVC via copolymerization or grafting.
Coatings Industry: Reacts with diols or polyols to form ether linkages, yielding coatings with excellent weather resistance, gloss, and ductility.
Oilfield Applications: Serves as a fluid loss control agent, oil-water separation aid, or enhancer in drilling fluids due to its water solubility and surface activity.
Other Fields: Used in pharmaceuticals, pesticides, adhesives, plastic films, and textile printing/dyeing.
