General description

1-Vinyl-2-pyrrolidinone is a colorless to yellow liquid, with a characteristic odor. Its melting point is around 13.5oC and boils at about 90-92oC. VP is completely miscible in water and in most organic solvents but partially miscible in aliphatic hydrocarbons. Industrial production of VP by reacting 2-pyrrolidone with acetylene at high pressure and temperature has been reported. The vinylation process proceeds in liquid phase and is catalyzed by 3-pyrrolidone -potassium hydroxide.

Application

1-Vinyl-2-pyrrolidinone (VP) is used in the study of macrophotoinitiator characteristics of poly (vinylchloride) type molecules. Also, used to study the genotoxicity of polyvinylpyrrolidone coated silver nanoparticles.

The manufacture of monomers for use in ophthalmic applications is driven by the need for higher purity, improved reliability of manufacturing supply, but ultimately by the need for the increased comfort, convenience, and safety of contact lens wearers. Daily wear contact lenses have the potential to fill this need for many customers; however, their widespread use is constrained by higher costs compared to weekly- or monthly-based lenses. New approaches that improve cost structure and result in higher quality raw materials are needed to help make contact lenses more affordable and accelerate growth of the contact lens market.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
