一般說明

1-乙烯基-2-吡咯烷酮是一种无色至黄色的液体，具有特征性的气味。它的熔点约为13.5oC而沸点约为90-92oC。VP与水以及大多数有机溶剂完全混溶，但在脂肪烃中是部分混溶的。在高压和高温下通过使2-吡咯烷酮与乙炔发生反应的VP工业生产已得到了报道。乙烯基化过程是在液相中进行的，并由3-吡咯烷酮-氢氧化钾催化。

應用

1-乙烯基-2-吡咯烷酮（VP）用于研究聚（氯乙烯）型分子的大分子光引发剂特性。此外，还用于研究聚乙烯吡咯烷酮包覆的银纳米粒子的遗传毒性。

Continuous Flow Manufacturing for Monomer Synthesis

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.
