Vinylpyrrolidone (NVP) is a colorless or light yellow transparent liquid with a slight odor at room temperature. It is easily soluble in water and a variety of organic solvents and is very easy to hydrolyze and polymerize. It is a key monomer for the synthesis of polymers such as polyvinylpyrrolidone (PVP).

Raw material properties, application scenarios and storage points

Core use: Vinyl pyrrolidone is a key raw material for the synthesis of polyvinyl pyrrolidone, which is widely used in many industries.
Multiple applications: Used in medicine to prepare drug adhesives and coating materials; in the cosmetics field as a raw material for hair spray, mousse and some skin care products; in industry, it can be used for acetylene and butadiene extraction, natural gas desulfurization, and can also serve as an insecticide component and pigment dispersant.
Storage points: It needs to be kept airtight, stored in a light-proof, low-temperature environment, and maintained in neutral or weakly alkaline conditions.
